Comm Port  
The Comm Port (also referred to as the Console/Comm Port) allows you to access  
the console interface (CI) screens and customize your network using the supplied  
menus and screens (see Chapter 3, Using the Console Interface).  
The Console/Comm Port is a DB-9, RS-232-D male serial port connector. You can  
use this connector to connect a management station or console/terminal to the  
switch by using a straight-through DB-9 to DB-9 standard serial port cable (see  
Console/Comm Porton page 2-10).

Introduction to the BayStack 410-24T Switch  
Note: The Console/Comm Port is configured as a data communications  
equipment (DCE) connector. Ensure that your RS-232 cable pinouts are  
configured for DCE connections (see DB-9 (RS-232-D) Console/Comm Port  
Connectoron page D-5).  
The console port default settings are: 9600 baud with eight data bits, one stop bit,  
and no parity as the communications format, with flow control set to Xon/Xoff.  
Uplink/Expansion Slot  
The Uplink/Expansion slot allows you to attach optional media dependent  
adapters (MDAs) that support a range of media types (see Appendix B, Media  
Dependent Adaptersfor more information about MDA types available from  
Nortel Networks).  
10BASE-T Port Connectors  
The BayStack 410-24T switch uses 10BASE-T (8-pin modular) port connectors.  
All BayStack 410-24T switches are shipped with port connectors configured as  
MDI-X (media-dependent interface-crossover). These ports connect over straight  
cables to the network interface controller (NIC) card in a node or server, similar to  
hub or Ethernet switch, you need a crossover cable unless an MDI connection  
exists on the associated port of the attached device (see MDI and MDI-X  
Deviceson page D-2).  
The switch ports also support half- and full-duplex mode operation (see also  
Connecting 10BASE-T Ports and 10/100 MDA Portson page 2-8).  
The switch uses RJ-45 port connectors to connect to 10BASE-T Ethernet  
segments or nodes.  
Note: 10BASE-T/100BASE-TX MDA ports (optional) must use Category 5  
UTP cable to accommodate the 100BASE-TX functionality.  
See Appendix D, Connectors and Pin Assignmentsfor more information about  
the RJ-45 port connectors.

Using the BayStack 410-24T 10BASE-T Switch  
RPSU Connector  
The RPSU connector allows you to connect a backup power supply unit to the  
switch. Nortel Networks provides an (optional) high-power redundant power  
supply unit (HRPSU) for this purpose. The HRPSU is a hot-swappable power  
supply unit that provides uninterrupted operation to up to four BayStack 410-24T  
switches in the event that any of the switch power supplies fail.  
Nortel Networks provides the HRPSU power rack (Order No. AA0002001) with  
four slots for power supply modules (Order No. AA0005003). Each HRPSU can  
support up to four BayStack 410-24T switches. Installation instructions are  
provided with the HRPSU.  
Contact your Nortel Networks sales representative for more information about the  
HRPSU.  
Cascade Module Slot  
The Cascade Module slot allows you to attach an optional BayStack 400-ST1  
Cascade Module to the switch (see Stack Operationon page 1-27).  
You can connect up to eight BayStack 410-24T switches into a redundant stack  
configuration. BayStack 410-24T switches use a fail-safe cascade stacking  
architecture which, in the unlikely event of a switch failure, maintains the integrity  
of the remaining stack: all signals are looped back at the point of failure. Because  
each unit in the stack has a full copy of the stack configuration, operation of the  
stack continues without affecting application connectivity.  
Any mix of up to eight BayStack 410-24T switches and BayStack 450 switches  
can be stacked to provide a total of 224 ports (when all MDA slots are configured  
with the maximum port availability).  
Installation instructions are provided with each BayStack 400-ST1 Cascade  
Module (see Installing the BayStack 400-ST1 Cascade Module). See your Nortel  
Networks sales representative for ordering information.  
Cooling Fans  
The variable-speed cooling fans (not shown) are located on one side of the switch  
to provide cooling for the internal components. When you install the switch, be  
sure to allow enough space on both sides of the switch for adequate air flow.

Using the BayStack 410-24T 10BASE-T Switch  
Virtual Local Area Networks (VLANs)  
In a traditional shared-media network, traffic generated by a station is propagated  
to all other stations on the local segment. Therefore, for any given station on the  
shared Ethernet, the local segment is the collision domain because traffic on the  
segment has the potential to cause an Ethernet collision. The local segment is also  
the broadcast domain because any broadcast is sent to all stations on the local  
segment. Although Ethernet switches and bridges divide a network into smaller  
collision domains, they do not affect the broadcast domain. In simple terms, a  
virtual local area network provides a mechanism to fine-tune broadcast domains.  
Your BayStack 410-24T switch allows you to create two types of VLANs:  
Port-based VLANs  
A port-based VLAN is a VLAN in which the ports are explicitly configured to  
be in the VLAN. When you create a port-based VLAN, you assign a Port  
VLAN Identifier (PVID) and specify which ports belong to the VLAN. The  
PVID is used to coordinate VLANs across multiple switches.  
Protocol-based VLANs  
A protocol-based VLAN is a VLAN in which you assign your switch ports as  
members of a broadcast domain, based on the protocol information within the  
packet. Protocol-based VLANs can localize broadcast traffic and assure that  
only the protocol-based VLAN ports are flooded with the specified protocol  
type packets.  
Your switch ports can be members of multiple protocol-based VLANs that are  
not based on the same protocol. Only tagged ports can be members of  
multiple protocol-based VLANs that are based on the same protocol.  
BayStack 410-24T switches support up to 64 port-based or protocol-based  
VLANs. When a switch port is configured to be a member of a VLAN, it is added  
to a group of ports (workgroup) that belong to one broadcast domain. You can  
assign different ports (and therefore the devices attached to these ports) to  
different broadcast domains. This feature allows network flexibility because you  
can reassign VLANs to accommodate network moves, additions, and changes,  
eliminating the need to change physical cabling.  
For more information about VLANs, see IEEE 802.1Q VLAN Workgroupson  
page 1-36.

Introduction to the BayStack 410-24T Switch  
Security  
Your BayStack 410-24T switch security feature can provide two levels of security  
for your local area network (LAN):  
RADIUS-based security -- Limits administrative access to the switch through  
user authentication.  
MAC address-based security -- Limits access to the switch based on allowed  
source MAC addresses.  
Figure 1-5 shows a typical campus configuration using the BayStack 410-24T  
switch security features. This example assumes that the switch, the teachers’  
offices and classrooms, and the library are physically secured. The student  
dormitory may (or may not be) physically secure.

Using the BayStack 410-24T 10BASE-T Switch  
In this configuration example, the following security measures are implemented:  
The switch  
-- RADIUS-based security is used to limit administrative access to the switch  
through user authentication (see RADIUS-Based Network Securityon  
page 1-15).  
-- MAC address-based security is used to allow up to 448 authorized stations  
(MAC addresses) access to one or more switch ports  
(see MAC Address-Based Securityon page 1-15).  
-- The switch is located in a locked closet, accessible only by authorized  
Technical Services personnel.  
Student dormitory  
Dormitory rooms are typically occupied by two students and have been  
prewired with two RJ-45 jacks. Only students who are authorized (as  
specified by the MAC address-based security feature) can access the switch  
on the secured ports.  
Teachersoffices and classrooms  
The PCs that are located in the teachersoffices and in the classrooms are  
assigned MAC address-based security that is specific for each classroom and  
office location. The security feature logically locks each wall jack to the  
specified station and prevents unauthorized access to the switch should  
someone attempt to connect a personal laptop PC into the wall jack. The  
printer is assigned as a single station and is allowed full bandwidth on that  
switch port.  
It is assumed that all PCs are password protected and that the classrooms and  
offices are physically secured.  
Library  
The wall jacks in the library are set up so that the PCs can be connected to any  
wall jack in the room. This allows the PCs to be moved anywhere in the room.  
The exception is the printer, which is assigned as a single station with full  
bandwidth to that port.  
It is assumed that all PCs are password protected and that access to the library  
is physically secured.

Introduction to the BayStack 410-24T Switch  
RADIUS-Based Network Security  
The RADIUS-based security feature allows you to set up network access control,  
using the RADIUS (Remote Authentication Dial-In User Services) security  
protocol. The RADIUS-based security feature uses the RADIUS protocol to  
authenticate local console and TELNET logins.  
You will need to set up specific user accounts (user names and passwords, and  
Service-Type attributes) on your RADIUS server before the authentication  
process can be initiated. To provide each user with appropriate levels of access to  
the switch, set the following username attributes on your RADIUS server:  
Read-write access -- Set the Service-Type field value to Administrative.  
For detailed instructions about setting up your RADIUS server, refer to your  
RADIUS server documentation.  
For instructions on using the console interface (CI) to set up the Radius-based  
security feature, see Console/Comm Port Configurationon page 3-82.  
MAC Address-Based Security  
The MAC address-based security feature allows you to set up network access  
control, based on source MAC addresses of authorized stations.  
You can:  
Create a list of up to 448 MAC addresses and specify which addresses are  
authorized to connect to your switch or stack configuration. The 448 MAC  
addresses can be configured within a single standalone switch or they can be  
distributed in any order among the units in a single stack configuration.  
Specify which of your switch ports each MAC address is allowed to access.  
The options for allowed port access include: NONE, ALL, and single or  
multiple ports that are specified in a list, for example, 1/1-4,1/6,2/9 (see Port  
List Syntaxon page 3-33).  
Specify optional actions to be exercised by your switch if the software detects  
a security violation.  
The response can be to send a trap, turn on destination address (DA) filtering,  
disable the specific port, or any combination of these three options.

For instructions on using the console interface (CI) to set up network access  
control, see MAC Address-Based Securityon page 3-22.  
The MAC address-based security feature is based on Nortel Networks  
BaySecureLAN Access for Ethernet, a real-time security system that safeguards  
Ethernet networks from unauthorized surveillance and intrusion.  
To learn more about the Nortel Networks BaySecure LAN Access for Ethernet,  
refer to the Bay Networks Guide to Implementing BaySecure LAN Access for  
Ethernet (Part number 345-1106A).  
The BayStack 410-24T switch can prioritize the order in which packets are  
forwarded, on a per-port basis.  
For more information about the IEEE 802.1p prioritizing feature, see IEEE  
802.1p Prioritizingon page 1-57.  
For conserving bandwidth and controlling IP Multicast, the IGMP snooping  
feature can provide the same benefit as IP Multicast routers, but in the local area.  
For more information about the IGMP snooping feature, see IGMP Snoopingon  
page 1-52.  
Configuration and Switch Management  
The BayStack 410-24T switch is shipped directly from the factory ready to  
operate in any 10BASE-T network. Optional MDAs are available for connecting  
to 100BASE-T networks. You can manage the switch using the Nortel Networks  
Optivity® network management software, Nortel Networks Device Manager  
Software, or any generic SNMP-based network management software; however,  
you must assign an IP address to the switch or stack, depending on the mode of  
operation. You can set both addresses by using the Console/Comm Port or BootP,  
which resides on the switch. For more information about using the Console/  
Comm Port to configure the switch, see Chapter 3, Using the Console Interface.”

Introduction to the BayStack 410-24T Switch  
Flash Memory Storage  
The following two sections describe switch parameters that are stored in flash  
memory.  
Switch Software Image  
Your switchs software image is stored in flash memory. The flash memory allows  
you to update your switch software image with a newer version, without changing  
the switch hardware (see Software Downloadon page 3-102). An in-band  
connection between the switch and the TFTP load host is required to download  
the software image.  
If a BootP server is set up properly on the network and the BayStack 410-24T  
switch detects a corrupted software image during the self-test, the switch  
automatically uses TFTP to download a new software image.  
Configuration Parameters  
Certain configuration parameters, including the system characteristics strings,  
some VLAN parameters, IGMP configuration parameters, and the MultiLink  
Trunk names are stored in flash memory. These parameters are updated every 10  
minutes or whenever you issue the Reset command.  
Note: Do not power off the switch within ten minutes of changing any  
configuration parameters, unless you first issue the Reset command. Powering  
down the switch within 10 minutes of changing configuration parameters  
(without resetting) can cause the changed configuration parameters to be lost.

Using the BayStack 410-24T 10BASE-T Switch  
Autosensing and Autonegotiation  
BayStack 410-24T switches are autosensing and autonegotiating devices. The  
term autosense refers to a ports ability to sense the speed of an attached device.  
The term autonegotiation refers to a standardized protocol (IEEE 802.3u) that  
exists between two IEEE 802.3u-capable devices.  
Because the BayStack 410-24T switch uses fixed 10BASE-T ports, the  
autonegotiation feature does not negotiate the port speed when connecting to  
another IEEE 802.3u-capable device. The BayStack 410-24T switch only  
negotiates the best duplex mode.  
When an optional 10/100 BASE-T MDA is installed, the autonegotiation feature  
selects the best of both speed and duplex modes for that connection. The MDA  
ports negotiate down from 100 Mb/s speed and full-duplex mode until a supported  
speed and duplex mode is acknowledged by the attached device.  
Autosensing is used when the attached device is not capable of autonegotiation or  
is using a form of autonegotiation that is not compatible with the IEEE 802.3u  
autonegotiation standard. In this case, because it is not possible to sense the  
duplex mode of the attached device, the BayStack 410-24T switch reverts to  
half-duplex mode.  
For more information about autosensing and autonegotiation modes, see  
Autonegotiation Modeson page 4-7.  
MultiLink Trunking  
The MultiLink Trunking feature allows you to group multiple ports (up to four)  
together when forming a link to another switch or server, thus increasing  
aggregate throughput of the interconnection between two devices (up to 800 Mb/s  
in full-duplex mode when an optional 100BASE-T MDA is installed). BayStack  
410-24T switches can be configured with up to six MultiLink Trunks. The trunk  
members can be configured within a single unit in the stack or distributed between  
any of the units within the stack configuration (distributed trunking).  
For more information about the MultiLink Trunking feature, see MultiLink  
Trunkson page 1-61.

Introduction to the BayStack 410-24T Switch  
IEEE 802.1Q VLANs  
BayStack 410-24T switches support up to 64 port-based VLANs with IEEE  
802.1Q tagging available per port.  
When a switch port is configured to be a member of a VLAN, it is added to a  
group of ports (workgroup) that belong to one broadcast domain. You can assign  
different ports (and therefore the devices attached to these ports) to different  
broadcast domains.  
This feature allows network flexibility because you can reassign VLANs to  
accommodate network moves, additions, and changes, eliminating the need to  
change physical cabling.  
For more information about 802.1Q VLANs, see IEEE 802.1Q VLAN  
Workgroupson page 1-36.  
Port Mirroring  
The port mirroring feature (sometimes referred to as conversation steering) allows  
a user to designate a single switch port as a traffic monitor for up to two specified  
ports or two media access control (MAC) addresses.  
You can specify Port-Based monitoring, where all traffic on specified ports is  
monitored, or Address-Based monitoring, where traffic between specified MAC  
You can attach a probe device (such as a Nortel Networks StackProbe, or  
equivalent) to the designated monitor port.  
For more information about the port mirroring feature, see Port Mirroring  
(Conversation Steering)on page 1-80.

Using the BayStack 410-24T 10BASE-T Switch  
BootP Automatic IP Configuration/MAC Address  
The BayStack 410-24T switch has a unique 48-bit hardware address, or MAC  
address, that is printed on a label on the back panel. You use this MAC address  
when you configure the network BootP server to recognize the BayStack 410-24T  
switch BootP requests.  
A properly configured BootP server enables the switch to automatically learn its  
assigned IP address, subnet mask, IP address of the default router (default  
gateway), and software image file name.  
When the switch is participating in a stack configuration, a Stack MAC address is  
automatically assigned during the stack initialization. The base units MAC  
address, with a software offset, is used for the Stack MAC address.  
For example, if the base units MAC address is:  
00-00-82-99-44-00  
and the Stack software offset is:  
1F  
then the Stack MAC address becomes:  
00-00-82-99-44-1F  
If another unit in the stack is assigned as the base unit, the MAC address of the  
new base unit (with offset) now applies to the stack configuration. The original  
stack IP address still applies to the new base unit.  
For an example of a BootP configuration file, see Appendix F, Sample BootP  
Configuration File.”

High-Density Switched Workgroup Application  
Figure 1-8 shows a BayStack 410-24T switch using an (optional) 400-4TX MDA  
to connect to a BayStack 450 switch. The Baystack 450 switch provides a  
high-speed connection to a Nortel Networks Accelar1100 switch. BayStack 303  
and 304 switches are also shown in this high-density workgroup example.  
The Accelar 1100 switch is used as a backbone switch, connecting to the  
BayStack 450 switch configured with a gigabit (1000BASE-SX) MDA for  
maximum bandwidth. The BayStack 303 and 304 switches have 100 Mb/s  
connections to the BayStack 410-24T switch, a 100BASE-TX hub, and a  
100 Mb/s server and 10 Mb/s connections to DTE (data terminal equipment).  
See the Nortel Networks library Web page: support.baynetworks.com/library/ for

Figure 1-9 shows eight switches (a single BayStack 450 switch and seven  
BayStack 410-24T switches) that are stacked together as a single managed unit. If  
any unit in the stack fails, the remaining stack remains operational.  
As shown in Figure 1-9, an Accelar 1100 switch is used as a backbone switch,  
connecting to a BayStack 450 switch with an optional gigabit 1000BASE-SX  
MDA for maximum bandwidth (the BayStack 410-24T switch does not support  
gigabit MDAs).  
This configuration uses optional BayStack 400-ST1 Cascade Modules to connect  
the switches in the fail-safe stack. For an overview of the fail-safe stacking feature

Introduction to the BayStack 410-24T Switch  
Stack Operation  
BayStack 410-24T switches provide fail-safe stacking when you install the  
optional BayStack 400-ST1 Cascade Module (see Fail-Safe Stack Application”  
on page 1-26). You can connect up to eight switches to provide uninterrupted  
connectivity for up to 224 ports. The entire stack is manageable as a single unit.  
Installation instructions are provided with the BayStack 400-ST1 Cascade Module  
(see your Nortel Networks sales representative for ordering information).  
BayStack 400-ST1 Cascade Module  
The front panel components of the BayStack 400-ST1 Cascade Module are shown

configuration (see Initial Installationon page 1-29). The Unit Select switch  
status is displayed on the BayStack 410-24T switch LED display panel. When the  
Unit Select switch is in the Base (up) position, all other Unit Select switches in the  
stack configuration must be set to Off (down).  
Cascade A In Connector  
Provides an attachment point for accepting a cascade cable connection from an  
adjacent unit in the stack. A return cable from this units Cascade A Out connector  
to the adjacent units Cascade A In connector completes the stack connection (see

Introduction to the BayStack 410-24T Switch  
Note: For stacking three or more units (maximum 8 units per stack), order the  
optional 1 meter (3.28 ft.) cascade return cable (Order No. AL2018001).  
Base Unit  
The base unit is the unique stack unit that is configured by the Unit Select switch  
on the front panel of the 400-ST1 cascade module. One unit in the stack must be  
configured as the base unit; all other units in the stack must have their Unit Select  
switch set to Off (see Unit Select Switchon page 1-28). Any single unit in the  
stack can be assigned as the base unit.  
Note: Although any single unit in the stack can be assigned as the base unit,  
when mixing BayStack models in a single stack, Nortel Networks  
recommends that you assign the unit with the highest bandwidth as the base  
unit. The additional workload of the base unit is optimized by using the higher  
bandwidth model switch.  
The physical ordering of all of the other units in the stack is determined by the  
position of the base unit within the stack. This is important for management  
applications that view the physical ordering of the units within the stack.  
Some characteristics of the base unit are described in the following sections.  
Initial Installation  
During the initial installation of the stack, the software automatically determines  
the physical order of all units in the stack according to the position of the base unit  
within the stack. Thereafter, the individual units maintain their original unit  
numbering, even if the position of one or more units in the stack is changed (you  
can renumber the units using the Renumber Stack Units screen; see Renumber  
Stack Unitson page 3-89).  
For example, when the stack is initially powered up, the base unit becomes unit 1  
and the unit that the base unit connects to (via the Cascade A Out cable) becomes  
unit 2 (and the next unit is unit 3 and so on), until the maximum stack  
configuration (up to 8 units) is reached. If the base unit is changed to another unit  
in the stack, the new base unit keeps its original unit number in the stack.

Using the BayStack 410-24T 10BASE-T Switch  
Stack MAC Address  
The Stack MAC address is automatically assigned during the stack initialization.  
The base units MAC address, with a software offset, is used for the Stack MAC  
address.  
For example, if the base units MAC address is:  
00-00-82-99-44-00  
and the Stack software offset is: 1F  
then the Stack MAC address becomes:  
00-00-82-99-44-1F  
If another unit in the stack is assigned as the base unit, the MAC address of the  
new base unit (with offset) now applies to the stack configuration. The original  
stack IP address still applies to the new base unit.  
Temporary Base Unit  
If an assigned base unit fails, the next unit in the stack order automatically  
becomes the new temporary base unit. This change is indicated by the Base LED  
on the temporary base units LED display panel turning on (yellow). For detailed  
information about the base LED, see Table 1-1 on page 1-4.  
This automatic process is a temporary safeguard only. If the stack configuration  
loses power, the temporary base unit will not power up as the base unit when  
power is restored. For this reason, you should always assign the temporary base  
unit as the base unit (set the Unit Select switch to Base) until the failed unit is  
repaired or replaced.  
Note: If you do not reassign the temporary base unit as the new base unit, and  
the temporary base unit fails, the next unit directly downstream from this unit  
becomes the new temporary base unit. This process can continue until there  
are only two units left in the stack configuration.

Introduction to the BayStack 410-24T Switch  
Removing a Unit from the Stack  
If a unit is removed from the stack (therefore operating in standalone mode), the  
following switch configuration settings revert back to the settings configured  
before the unit became a member of the stack:  
IP address  
Console password  
TELNET password  
SNMP community strings  
Stack Configurations  
As shown in Figure 1-12, the cascade connectors and cables on the 400-ST1 front  
panel provide the ability to stack up to eight BayStack switches. With 400-4TX  
MDAs installed in each switch, the stack can accommodate a maximum of 224  
switch ports.  
Because stack parameters are associated with the base unit (see Initial  
Installationon page 1-29), the physical stack order depends on the base units  
position and whether the stack is configured stack up or stack down.

Stack Down Configuration Example  
Certain network management station (NMS) applications assume a stack-down  
configuration for the graphical user interface (GUI) that represents the stack (see  
Figure 1-13 on page 1-33). For this reason, Nortel Networks recommends that you  
always configure the top unit in the stack as the base unit.  
In any stack configuration, the following applies:  
The entire stack powers up as a single logical unit within 30 seconds after the  
base unit initialization.  
You can attach an RS-232 communications cable to the Console/Comm port  
of any switch in the stack.

Using the BayStack 410-24T 10BASE-T Switch  
You can downline upgrade the entire stack from any switch in the stack.  
You can access and manage the stack using a TELNET connection or any  
generic SNMP management tool through any switch port that is part of the  
stack configuration.  
When stacking three or more switches, use the longer (1-meter) cascade  
max-return cable (PN 303979-A) to complete the link from the last unit in the  
stack to the base unit.  
Redundant Cascade Stacking Feature  
BayStack 410-24T Switches allow you to connect up to 8 units into a redundant  
cascade stack. If any single unit fails or if a cable is accidently disconnected, other  
units in the stack remain operational, without interruption.  
Figure 1-14 shows an example of how a stack configuration reacts to a failed or  
powered-down unit in the stack configuration:  
1. As shown in Figure 1-14, unit 3 is not operational.  
This can be the result of a failed unit, or simply because the unit was powered  
down.  
2. Unit 2 and unit 4, directly upstream and downstream from unit 3, sense the  
loss of link signals from unit 3.  
Unit 2 and unit 4 automatically loop their internal stack signals (A and B).  
The Cas Up LED for unit 2 and the Cas Dwn LED for unit 4 turn on  
(yellow) to indicate that the stack signals are looped.  
3. The remaining stack units remain connected.  
Although the example shown in Figure 1-14 shows a failed unit causing the stack  
to loop signals at the points of failure (A and B), the system reacts the same way if  
a cable is removed.

IEEE 802.1Q VLAN Workgroups  
BayStack 410-24T switches support up to 64 VLANs with 802.1Q tagging  
available per port. Ports are grouped into broadcast domains by assigning them to  
the same VLAN. Frames received in one VLAN can only be forwarded within  
that VLAN, and IP Multicast frames and unknown unicast frames are flooded  
only to ports in the same VLAN.  
Setting up virtual LANs (VLANs) is a way to segment networks to increase  
network capacity and performance without changing the physical network  
topology (Figure 1-15). With network segmentation, each switch port connects to  
a segment that is a single broadcast domain. When a switch port is configured to  
be a member of a VLAN, it is added to a group of ports (workgroup) that belong  
to one broadcast domain.  
The BayStack 410-24T switch allows you to assign ports to VLANs using the  
console, TELNET, or any generic SNMP-based network management software.  
You can assign different ports (and therefore the devices attached to these ports) to  
different broadcast domains. This feature allows network flexibility because you  
can reassign VLANs to accommodate network moves, additions, and changes,  
eliminating the need to change physical cabling.

Introduction to the BayStack 410-24T Switch  
IEEE 802.1Q Tagging  
BayStack 410-24T switches operate in accordance with the IEEE 802.1Q tagging  
rules. Important terms used with the 802.1Q tagging feature are:  
VLAN identifier (VID) -- the 12-bit portion of the VLAN tag in the frame  
header that identifies an explicit VLAN.  
Port VLAN identifier (PVID) -- a classification mechanism that associates a  
port with a specific VLAN (see Figures 1-17 to 1-20).  
Tagged frame -- the 32-bit field (VLAN tag) in the frame header that  
identifies the frame as belonging to a specific VLAN. Untagged frames are  
marked (tagged) with this classification as they leave the switch through a port  
that is configured as a tagged port.  
Untagged frame -- a frame that does not carry any VLAN tagging  
information in the frame header.  
VLAN port members -- a set of ports that form a broadcast domain for a  
specific VLAN. A port can be a member of one or more VLANs.  
Untagged member -- a port that has been configured as an untagged member  
of a specific VLAN. When an untagged frame exits the switch through an  
untagged member port, the frame header remains unchanged. When a tagged  
frame exits the switch through an untagged member port, the tag is stripped  
and the tagged frame is changed to an untagged frame.  
Tagged member -- a port that has been configured as a member of a specific  
VLAN. When an untagged frame exits the switch through a tagged member  
port, the frame header is modified to include the 32-bit tag associated with the  
VLAN assigned to that frame. When a tagged frame exits the switch through a  
tagged member port, the frame header remains unchanged (original VID  
remains).  
User_priority -- a three-bit field in the header of a tagged frame. The field is  
interpreted as a binary number, therefore has a value of 0 - 7. This field allows  
the tagged frame to carry the user-priority across bridged LANs where the  
individual LAN segments may be unable to signal priority information.  
Port priority -- the priority level assigned to untagged frames received on a  
port. This value becomes the user_priority for the frame. Tagged packets get  
their user_priority from the value contained in the 802.1Q frame header.  
Unregistered packet -- a tagged frame which contains a VID where the  
receiving port is not a member of that VLAN.

Using the BayStack 410-24T 10BASE-T Switch  
Filtering database identifier (FID) -- the specific filtering/forwarding database  
within the BayStack 410-24T switch that is assigned to each VLAN. The  
current version of software assigns all VLANs to the same FID. This is  
referred to as Shared VLAN Learning in the IEEE 802.1Q specification.  
The default configuration settings for BayStack 410-24T switches have all ports  
set as untagged members of VLAN 1 with all ports configured as PVID = 1. Every  
VLAN is assigned a unique VLAN identifier (VID) which distinguishes it from  
all other VLANs. In the default configuration example shown in Figure 1-16, all  
incoming packets are assigned to VLAN 1 by the default port VLAN identifier  
(PVID =1). Untagged packets enter and leave the switch unchanged.

Introduction to the BayStack 410-24T Switch  
VLANs Spanning Multiple Switches  
You can use VLANs to segment a network within a switch. When connecting  
multiple switches, it is possible to connect users of one VLAN with users of that  
same VLAN in another switch. However, the configuration guidelines depend on  
whether both switches support 802.1Q tagging.  
With 802.1Q tagging enabled on a port for a VLAN, all frames leaving the port for  
that VLAN are marked as belonging to that specific VLAN. Users can assign  
specific switch ports as members of one or more VLANs that span multiple  
switches, without interfering with the spanning tree protocol.  
VLANs Spanning Multiple 802.1Q Tagged Switches  
Figure 1-21 shows VLANs spanning two BayStack 410-24T switches. 802.1Q  
tagging is enabled on S1, port 2 and on S2, port 1 for VLAN 1 and VLAN 2. Both  
ports are tagged members of VLAN 1 and VLAN 2.

Using the BayStack 410-24T 10BASE-T Switch  
Because there is only one link between the two switches, the Spanning Tree  
Protocol (STP) treats this configuration as any other switch-to-switch connection.  
For this configuration to work properly, both switches must support the 802.1Q  
tagging protocol.  
VLANs Spanning Multiple Untagged Switches  
Figure 1-22 shows VLANs spanning multiple untagged switches. In this  
configuration switch S2 does not support 802.1Q tagging and a single switch port  
on each switch must be used for each VLAN.  
For this configuration to work properly, spanning tree participation must be set to  
Disabled because the STP is not supported across multiple LANs.

VLANs Spanning Multiple Untagged Switches  
When the STP is enabled on these switches, only one link between each pair of  
switches will be forwarding traffic. Because each port belongs to only one VLAN  
at a time, connectivity on the other VLAN will be lost. Exercise care when  
configuring the switches to ensure that the VLAN configuration does not conflict  
with spanning tree configuration.

Introduction to the BayStack 410-24T Switch  
To connect multiple VLANs across switches with redundant links, the STP must  
be disabled on all participating switch ports. Figure 1-23 shows possible  
consequences of enabling the STP when using VLANs between untagged  
(non-802.1Q tagged) switches.

Possible Problems with VLANs and Spanning Tree Protocol  
As shown in Figure 1-23, with STP enabled, only one connection between S1 and  
S2 is forwarding at any time. Communications failure occurs between VLAN 2 of  
S1 and VLAN 2 of S2, blocking communications between Stations A and B.  
The link connecting VLAN 1 on Switches S1 and S2 is selected as the forwarding  
link based on port speed, duplex mode, and port priority. Because the other link  
connecting VLAN 2 is placed into Blocking mode, stations on VLAN 2 in switch  
S1 cannot communicate with stations in VLAN 2 on switch S2. With multiple  
links only one link will be forwarding.

Using the BayStack 410-24T 10BASE-T Switch  
BayStack 410-24T switches allow ports to exist in multiple VLANs for shared  
resources, such as servers, printers, and switch-to-switch connections. It is also  
possible to have resources exist in multiple VLANs on one switch as shown in  
Figure 1-24.  
In this example, clients on different broadcast domains share resources. The  
broadcasts from ports configured in VLAN 3 can be seen by all VLAN port  
members of VLAN 3.

In order for the above configuration to operate as described, the ports have to be  
set to participate as VLAN port members. When this is done, the switch  
establishes the appropriate broadcast domains within the switch (see Figure 1-25).

VLAN Broadcast Domains Within the Switch  
The broadcast domain for each of the VLANs shown in Figure 1-25 is created by  
configuring VLAN port memberships for each VLAN and then configuring each  
of the ports with the appropriate PVID/VLAN association:  
Ports 8, 6, and 11 are untagged members of VLAN 1.  
The PVID/VLAN association for ports 6 and 11 is: PVID = 1.  
Ports 2, 4, 10, and 8 are untagged members of VLAN 2.  
The PVID/VLAN association for ports 2, 4, and 10 is: PVID = 2.  
Ports 2, 4, 10, 8, 6, and 11 are untagged members of VLAN 3.  
The PVID/VLAN association for port 8 is: PVID = 3.  
The following steps show how to use the VLAN configuration screens to  
configure the VLAN 3 broadcast domain shown in Figure 1-25.

VLAN Workgroup Summary  
This section summarizes the VLAN workgroup examples discussed in the  
previous sections of this chapter.  
As shown in Figure 1-30, switch S1 (a BayStack 410-24T switch) is configured  
with multiple VLANs:  
Ports 1, 6, 11, and 12 are in VLAN 1.  
Port 8 is in VLAN 3.  
Because switch S4 does not support 802.1Q tagging, a single switch port on each  
switch must be used for each VLAN (see VLANs Spanning Multiple Untagged  
Switcheson page 1-42).

Introduction to the BayStack 410-24T Switch  
VLAN Configuration Rules  
VLANs operate according to specific configuration rules. When creating VLANs,  
consider the following rules that determine how the configured VLAN reacts in  
any network topology:  
All ports that are involved in port mirroring must have memberships in the  
same VLANs. If a port is configured for port mirroring, the ports VLAN  
membership cannot be changed.  
If a port is a trunk group member, all trunk members are added or deleted  
from the VLAN.  
All ports involved in trunking and port mirroring must have the same VLAN  
configuration. If a port is on a trunk with a mirroring port, the VLAN  
configuration cannot be changed.  
VLANs are not dependent on rate limiting settings.  
If a port is an IGMP member on any VLAN, and is removed from a VLAN,  
the ports IGMP membership is also removed.  
When you add a port to a different VLAN, and it is already configured as a  
static router port, the port is configured as an IGMP member on that specific  
VLAN.  
For more information about configuring VLANs, see VLAN Configuration  
Menuon page 3-38.  
See also Appendix C, Quick Steps to Featuresfor configuration flowcharts that  
can help you use this feature.

Using the BayStack 410-24T 10BASE-T Switch  
IGMP Snooping  
BayStack 410-24T switches can sense IGMP host membership reports from  
attached stations and use this information to set up a dedicated path between the  
requesting station and a local IP Multicast router. After the pathway is established,  
the BayStack 410-24T switch blocks the IP Multicast stream from exiting any  
other port that does not connect to another host member, thus conserving  
bandwidth. The following discussion describes how BayStack 410-24T switches  
provide the same benefit as IP Multicast routers, but in the local area.  
Internet Group Management Protocol (IGMP), is used by IP Multicast routers to  
learn about the existence of host group members on their directly attached subnets  
(see RFC 2236). The IP Multicast routers get this information by broadcasting  
IGMP queries and listening for IP hosts reporting their host group memberships.  
This process is used to set up a client/server relationship between an IP Multicast  
source that provides the data streams and the clients that want to receive the data.  
Figure 1-31 shows how IGMP is used to set up the path between the client and  
server. As shown in this example, the IGMP host provides an IP Multicast stream  
to designated routers which forward the IP Multicast stream on their local network  
only if there is a recipient.  
The client/server path is set up as follows:  
1. The designated router sends out a host membership query to the subnet and  
receives host membership reports from end stations on the subnet.  
2. The designated routers then set up a path between the IP Multicast stream  
source and the end stations.  
3. Periodically, the router continues to query end stations on whether to continue  
participation.  
4. As long as any client continues to participate, all clients, including  
nonparticipating end stations on that subnet, receive the IP Multicast stream.  
Note: Although the nonparticipating end stations can filter the IP Multicast  
traffic, the IP Multicast still exists on the subnet and consumes bandwidth.  
IP Multicast can be optimized in a LAN by using IP Multicast filtering switches,  
such as the BayStack 410-24T switch.

IP Multicast Propagation With IGMP Routing  
The BayStack 410-24T switch can automatically set up IP Multicast filters so the  
IP Multicast traffic is only directed to the participating end nodes (see  
Figure 1-32).  
In Figure 1-32, switches S1 to S4 represent a LAN connected to a IP Multicast  
router. The router periodically sends Host Membership Queries to the LAN and  
listens for a response from end stations. All of the clients connected to switches  
S1 to S4 are aware of the queries from the router.

Using the BayStack 410-24T 10BASE-T Switch  
One client, connected to S2, responds with a host membership report. Switch S2  
intercepts the report from that port, and generates a proxy report to its upstream  
neighbor, S1. Also, two clients connected to S4 respond with host membership  
reports, causing S4 to intercept the reports and to generate a consolidated proxy  
report to its upstream neighbor, S1.

Switch S1 treats the consolidated proxy reports from S2 and S4 as if they were  
reports from any client connected to its ports, and generates a consolidated proxy  
report to the designated router. In this way, the router receives a single  
consolidated report from that entire subnet.

Introduction to the BayStack 410-24T Switch  
After the switches learn which ports are requesting access to the IP Multicast  
stream, all other ports not responding to the queries are blocked from receiving the

IGMP Snooping Configuration Rules  
The IGMP snooping feature operates according to specific configuration rules.  
When configuring your switch for IGMP snooping, consider the following rules  
that determine how the configuration reacts in any network topology:  
A port that is configured for port mirroring cannot be configured as a static  
router port.  
If a MultiLink Trunk member is configured as a static router port, all of the  
MultiLink Trunk members are configured as static router ports. Also, if a  
static router port is removed, and it is a MultiLink Trunk member, all  
MultiLink Trunk members are removed as static router port members,  
automatically.  
Static router ports must be port members of at least one VLAN.  
If a port is configured as a static router port, it is configured as a static router  
port for all VLANs on that port. The IGMP configuration is propagated  
through all VLANs of that port.  
If a static router port is removed, the membership for that port is removed  
from all VLANs of that port.  
The IGMP snooping feature is not STP dependent.  
The IGMP snooping feature is not rate-limiting dependent.  
The snooping field must be enabled for the proxy field to have any valid  
meaning.  
Static router ports are configured per VLAN and per IGMP Version.  
Note: Because IGMP snooping is set up per VLAN, all IGMP changes are  
implemented according to the VLAN configuration for the specified ports.  
For more information about using the IGMP snooping feature, see IGMP  
Configuration Menuon page 3-71.

can help you use this feature.

IEEE 802.1p Prioritizing  
You can use the VLAN Configuration screens to prioritize the order in which the  
switch forwards packets, on a per-port basis. For example, if messages from a  
specific segment are crucial to your operation, you can set the switch port  
connected to that segment to a higher priority level (by default, all switch ports are  
set to Low priority). Untagged packets received by the switch on that port are  
tagged according to the priority level you assign to the port (see Figure 1-34).

Port Transmit Queue  
As shown in Figure 1-35, the switch provides two transmission queues, a High  
transmission queue and a Low transmission queue, for any given port. Frames are  
assigned to one of these queues on the basis of user_priority using a traffic class  
table. This table is managed by using the Traffic Class Configuration screen  
(Figure 1-36). The table indicates the corresponding traffic class that is assigned  
to the frame, for each possible user_priority value. If the frame leaves the switch  
formatted as a tagged packet, the traffic class assigned to the frame is carried  
forward to the next 802.1p capable switch. This allows the packet to carry the  
assigned traffic class priority through the network until it reaches its destination.  
The following steps show how to use the Traffic Class Configuration screen to  
configure the port priority level shown in the example Figure 1-34.  
For more information about using the Traffic Class Configuration screen, see  
VLAN Configurationon page 3-40.

Introduction to the BayStack 410-24T Switch  
MultiLink Trunks  
A MultiLink Trunk (MLT)1 allows you to group up to four switch ports together to  
form a link to another switch or server, thus increasing aggregate throughput of  
the interconnection between the devices (up to 800 Mb/s in full-duplex mode with  
optional 100BASE-T/F MDAs installed). You can configure up to six MultiLink  
Trunks. The MLT members can reside on a single unit or on multiple units within  
the same stack configuration as a distributed trunk. MLT software detects  
misconfigured (or broken) trunk links and redirects traffic on the misconfigured or  
broken trunk link to other trunk members within that MLT.  
You can use the MultiLink Trunk Configuration screen to create switch-to-switch  
and switch-to-server MLT links (see Figure 1-38 and Figure 1-39).  
Figure 1-38 shows two trunks (T1 and T2) connecting switch S1 to switches S2  
and S3.

Using the BayStack 410-24T 10BASE-T Switch  
Each of the trunks shown in Figure 1-38 can be configured with up to four switch  
ports to provide maximum aggregate bandwidth through each trunk, in full-duplex  
mode. As shown in this example, when traffic between switch-to-switch  
connections approaches single port bandwidth limitations, creating a MultiLink  
Trunk can supply the additional bandwidth required to improve the performance.  
Figure 1-39 shows a typical switch-to-server trunk configuration. In this example,  
file server FS1 uses dual MAC addresses, using one MAC address for each  
network interface controller (NIC). For this reason, FS1 does not require a trunk  
assignment. FS2 is a single MAC server (with a four-port NIC) and is set up as  
trunk configuration T1.

client/server configuration. In this example, both servers are connected directly to  
switch S1. FS2 is connected through a trunk configuration (T1). The  
switch-to-switch connections are through trunks (T2, T3, T4, and T5).

Introduction to the BayStack 410-24T Switch  
Clients accessing data from the servers (FS1 and FS2) are provided with  
maximized bandwidth through trunks T1, T2, T3, T4, and T5. Trunk members  
can be selected randomly, as shown by T5.  
With spanning tree enabled, one of the trunks (T2 or T3) acts as a redundant  
(backup) trunk to switch S2. With spanning tree disabled, trunks T2 and T3 must  
be configured into separate VLANs for this configuration to function properly  
(see IEEE 802.1Q VLAN Workgroupson page 1-36).

Switch S4 is configured as follows:  
Trunk (read only) indicates the trunk (1 to 6) that corresponds to the switch  
ports specified in the Trunk Members fields.  
Trunk Members (Unit/Port) indicates the ports that can be configured, in  
each row, to create the corresponding trunk:  
Ports 5 and 11 are assigned as trunk members of trunk T1.  
STP Learning indicates the spanning tree participation setting for each of the  
trunks:  
Trunk 1 is enabled for Normal STP Learning.  
Trunk Mode (read only) indicates the Trunk Mode for each of the trunks:  
The Trunk Mode field value for trunk 1 is set to Basic. Source MAC addresses  
are statically assigned to specific trunk members for flooding and forwarding.  
This allows the switch to stabilize and distribute the data streams of source  
addresses across the trunk members.  
Trunk Status indicates the Trunk Status for each of the trunks. When it is set  
to Enabled, the configuration settings for that specific trunk are activated.  
Trunk Name indicates optional fields for assigning names to the  
corresponding configured trunks.  
The names chosen for this example provide meaningful information to the  
user (for example, S4:T5 to S1 indicates that Trunk 1, in switch S4, connects  
to Switch 1).

Introduction to the BayStack 410-24T Switch  
Before Configuring Trunks  
When you create and enable a trunk, the trunk members (switch ports) take on  
certain settings necessary for correct operation of the MultiLink Trunking feature.  
These settings, along with specific configuration rules, must be considered before  
configuring your MultiLink Trunk.  
Before configuring any MultiLink Trunk:  
1. Read the configuration rules provided in the next section, “MultiLink  
Trunking Configuration Rules.”  
2. Determine which switch ports (up to four) are to become trunk members  
(the specific ports making up the trunk):  
a. A minimum of two ports are required for each trunk.  
b. Ensure that the chosen switch ports are set to Enabled, using the Port  
Configuration screen (see “Port Configuration” on page 3-52) or  
through network management.  
c. Trunk member ports must have the same VLAN configuration.  
3. All network cabling should be complete and stable before configuring any  
trunks, to avoid configuration errors.  
4. Consider how the existing spanning tree will react to the new trunk  
configuration (see “Spanning Tree Considerations for MultiLink Trunks”  
on page 1-76).  
5. Consider how existing VLANs will be affected by the addition of a trunk.  
6. After completing the above steps, see “MultiLink Trunk Configuration”  
on page 3-57 for screen examples and field descriptions that will help you  
configure your MultiLink Trunks.  
MultiLink Trunking Configuration Rules  
The MultiLink Trunking feature is deterministic; that is, it operates according to  
specific configuration rules. When creating trunks, consider the following rules  
that determine how the MultiLink Trunk reacts in any network topology:  
Any port that participates in MultiLink Trunking must be an active port (set to  
Enabled via the Port Configuration screen or through network management).

Using the BayStack 410-24T 10BASE-T Switch  
All trunk members must have the same VLAN configuration before the Trunk  
Configuration screens Trunk Status field can be set to Enabled (see VLAN  
Configurationon page 3-40).  
When an active port is configured in a trunk, the port becomes a trunk member  
is set to Enabled, the spanning tree parameters for the port will change to  
reflect the new trunk settings.  
If spanning tree participation of any trunk member is changed (enabled or  
disabled), the spanning tree participation of all members of that trunk is  
changed similarly (see Spanning Tree Considerations for MultiLink Trunks”  
on page 1-76).  
When a trunk is enabled, the trunk spanning tree participation setting takes  
precedence over that of any trunk member. When a trunk is active, the trunk  
STP setting can be changed from either the Trunk Configuration screen or the  
Spanning Tree Configuration screen.  
If the VLAN settings of any trunk member are changed, the VLAN settings of  
all members of that trunk are changed similarly.  
When any trunk member is set to Disabled (not active) through the Port  
Configuration screen or through network management, the trunk member is  
removed from the trunk. The removed trunk member has to be reconfigured  
through the Trunk Configuration screen to rejoin the trunk. A screen prompt  
trunk members on the trunk.  
A trunk member cannot be configured as a monitor port (see Port Mirroring  
Configurationon page 3-64).  
Trunks cannot be monitored by a monitor port; however, trunk members can  
be monitored (see Port-Based Mirroring Configurationon page 1-81).  
All trunk members must have identical IGMP configurations.  
If the IGMP snooping configuration for any trunk member is changed, the  
IGMP snooping settings for all trunk members are changed.

How the MultiLink Trunk Reacts to Losing Distributed Trunk Members  
If your MultiLink Trunk (Figure 1-46) spans separate units in a stack  
configuration and any of those units (or trunked MDAs) becomes inactive from a  
loss of power or unit failure, the unaffected trunk members remain operational.

Spanning Tree Considerations for MultiLink Trunks  
The spanning tree Path Cost parameter is recalculated based on the aggregate  
bandwidth of the trunk. For example, Figure 1-47 shows a four-port trunk (T1)  
with two port members operating at 100 Mb/s and two at 10 Mb/s. Trunk T1  
provides an aggregate bandwidth of 220 Mb/s. The Path Cost for T1 is 4 (Path  
Cost = 1000/LAN speed, in Mb/s). Another three-port trunk (T2) is configured  
with an aggregate bandwidth of 210 Mb/s and a comparable Path Cost of 4. When  
the Path Cost calculations for both trunks are equal, the software chooses the trunk  
with the larger aggregate bandwidth (T1) to determine the most efficient path.

The switch can also detect trunk member ports that are physically misconfigured.  
For example, in Figure 1-48, trunk member ports 2, 4, and 6 of switch S1 are  
configured correctly to trunk member ports 7, 9, and 11 of switch S2. The  
Spanning Tree Port Configuration screen for each switch shows the port state field  
for each port in the Forwarding state.

Introduction to the BayStack 410-24T Switch  
Additional Tips About the MultiLink Trunking Feature  
When you create a MultiLink Trunk, the individual trunk members (the specific  
ports that make up the trunk) are logically connected and react as a single entity.  
For example, if you change spanning tree parameters for any trunk member, the  
spanning tree parameters for all trunk members are changed.  
All configured trunks are indicated in the Spanning Tree Configuration screen.  
The screens Trunk field lists the active trunks, adjacent to the port numbers that  
correspond to the specific trunk member for that trunk.  
When a trunk is active you can disable spanning tree participation using the Trunk  
Configuration screen or using the Spanning Tree Configuration screen.  
When a trunk is not active, the spanning tree participation setting in the Trunk  
Configuration screen does not take effect until the Trunk Status field is set to  
Enabled.  
The trunk is also viewed by management stations as a single spanning tree port.  
The spanning tree port is represented by the trunk member with the lowest port  
number. For example, if ports 13, 14, 15, and 16 are trunk members of trunk T1,  
the management station views trunk T1 as spanning tree port 13.  
For more information about using the MultiLink Trunking feature, see MultiLink  
Trunk Configurationon page 3-57.  
See also Appendix C, Quick Steps to Features,for configuration flowcharts that  
can help you use this feature.

Port Mirroring (Conversation Steering)  
You can designate one of your switch ports to monitor traffic on any two specified  
switch ports (port-based) or to monitor traffic to or from any two specified  
addresses that the switch has learned (address-based).  
Note: A probe device, such as the Nortel Networks StackProbeor  
equivalent, must be connected to the designated monitor port to use this feature  
(contact your Nortel Networks sales agent for details about the StackProbe).  
The following sections provide example configurations for both monitoring  
modes available with the port mirroring feature:  
Port-based mirroring  
Address-based mirroring  
A sample of the Port Mirroring Configuration screen is provided with each of the  
examples to support the network configuration example.  
Note that in the following examples, the displayed screens do not show all of the  
screen prompts that precede some actions. For example, when you configure a  
switch for port mirroring or when you modify an existing port mirroring  
configuration, the new configuration does not take effect until you respond [Yes]  
to the following screen prompt:  
Is your port mirroring configuration complete?  
[ Yes ]

Port Mirroring Configuration Rules  
The following configuration rules apply to any port mirroring configuration:  
A monitor port cannot be configured as a trunk member or IGMP member,  
and cannot be used for normal switch functions.  
When a port is configured and enabled as a monitor port, the port is  
automatically disabled from participating in the spanning tree. When the port  
is reconfigured as a standard switch port (no longer a monitor port), the port  
becomes enabled for spanning tree participation.  
When creating a port-based port mirroring configuration, be sure that the  
monitor port and both of the mirrored ports, port X and port Y, have the same  
configuration. Use the VLAN Configuration screen to configure the VLAN  
(see VLAN Configurationon page 3-40).  
VLAN configuration settings for any ports configured for port-based  
mirroring cannot be changed. Use the Port Mirroring Configuration screen to  
disable port mirroring (or reconfigure the port mirroring ports), then change  
the VLAN configuration settings.  
For port-based monitoring of traffic, use one of the following modes for  
monitoring broadcast, IP Multicast, or unknown DA frames:  
-- Monitor all traffic transmitted by port X.  
-- Monitor all traffic received and transmitted by port X.  
For more information about using the Port Mirroring feature, see Port Mirroring

Attaching Devices to the BayStack 410-24T Switch  
This section describes how to attach devices to the BayStack 410-24T switch ports  
and how to connect a console terminal to the switch Console/Comm port. You can  
use the console terminal to observe the power on self-test results and set up the  
switch, if required, as described later in this chapter.  
The BayStack 410-24T switch has an Uplink/Expansion slot that allows you to  
attach optional media dependent adapters (MDAs). The MDAs support a range of  
media types (see Appendix B, Media Dependent Adaptersfor more information  
about MDA types available from Nortel Networks). Refer to the documentation  
that came with your specific MDA for information about its cabling and LED  
indications.  
BayStack 410-24T switches provide Fail-Safe stackability when you install the  
optional BayStack 400-ST1 Cascade Module to your switches. Installation  
instructions are provided with the cascade module.  
Depending on your network configuration requirements, connect the RJ-45 port  
cables, the console port, and any optional MDA port cables as described in the  
following sections. After attaching the devices to the BayStack 410-24T switch,  
proceed to Connecting Poweron page 2-12 to connect the AC power cord and  
power up the switch.  
You can connect the BayStack 410-24T switch to any equipment that conforms to  
the IEEE 802.3 standard, such as the following devices:

Connecting 10BASE-T Ports and 10/100 MDA Ports  
Connect devices to the 10BASE-T ports and to the (optional) 10/100 MDA ports  
as shown in Figure 2-5.  
The 10BASE-T switch ports and the 10/100 MDA ports are configured with RJ-45  
connectors that are wired as MDI-X ports. As in conventional Ethernet repeater  
hubs, the BayStack 410-24T switch ports connect via straight-through cables to  
the network interface card (NIC) in a node or server. When connecting to an  
Ethernet hub or to another switch, you must use a crossover cable. See  
Appendix D, Connectors and Pin Assignments,for more information.  
A standard RJ-45 connection is provided to connect devices to the switch through  
the 10BASE-T ports and to the 10/100 MDA ports.  
Note: The 10/100 MDA ports must use Category 5 UTP cable to  
accommodate the 100BASE-TX functionality.  
To connect the RJ-45 port cables, insert the cable plug into the appropriate port  
connector until the release tab snaps into the locked position (Figure 2-5).

Installing the BayStack 410-24T Switch  
Initial Setup  
The BayStack 410-24T switch is designed for plug-and-playoperation; in most  
cases the switch can be installed and made operational using the system default  
settings (see Appendix E, Default Settings,for a list of default settings for the  
BayStack 410-24T switch).  
However, for the switch management function to become fully operational, certain  
parameters must be configured. A minimal configuration is required when you  
plan on remote management or TFTP operations.  
If you are configuring your BayStack 410-24T switches into a stack configuration,  
you will need to supply additional parameters to properly setup the stack.  
This section includes the following information:  
Instructions for the initial (standalone) switch setup  
Instructions for the initial stack setup  
After setting up your switch or stack configuration as described in the following  
sections, proceed to Chapter 3, Using the Console Interface,for detailed  
descriptions of the menus and screens you can use to customize your  
configuration.  
Standalone Switch Setup  
For the initial setup of a standalone switch, you need to enter the IP address of the  
switch, the subnet mask, and the gateway address (refer to Chapter 3, Using the  
Console Interface,for more information about configuring your BayStack  
410-24T switch).  
To set the IP address, subnet mask, and gateway address for the switch:  
1. Apply power to the switch.  
2. After the Nortel Networks logo screen appears, press [Ctrl]-Y.  
The Main Menu is displayed (Figure 2-13). The Main Menu hierarchy is

You can also manage the BayStack 410-24T switch using Bay Networks Optivity  
network management software or any generic SNMP-based management  
software; however, certain parameters such as the switch IP address, or stack IP  
address, if configured, must be supplied for the switch management function to  
become fully operational (see Initial Setupon page page 2-17).  
Note: If you have a properly configured BootP server in your network, it will  
detect the IP address; you will not need to configure the IP address.  
For information about SNMP, see your network management documentation.

Using the Console Interface  
BootP Disabled  
Allows the switch to be managed only by using the IP address set from the  
console terminal (this is the default mode for your switch).  
When selected, this mode operates as follows:  
The switch does not broadcast BootP requests, regardless of whether an IP  
address is set from the console terminal.  
The switch can be managed only by using the in-band IP address set from the  
console terminal.  
These actions take effect after the switch is reset or power cycled, even if an IP  
address is not currently in use.  
BootP or Last Address  
Allows the switch to be managed even if a BootP server is not reachable.  
When selected, this mode operates as follows:  
When the IP data is entered from the console terminal, the data becomes the  
in-band address of the switch and BootP requests are not broadcast. The  
switch can be managed using this in-band IP address.  
When the in-band IP address is not set from the console terminal, the switch  
broadcasts BootP requests until it receives a BootP reply containing an  
in-band IP address. If the switch does not receive a BootP reply that contains  
an in-band IP address within 10 minutes, the switch uses the last in-band IP  
address it received from a BootP server. This IP information is displayed in  
the Last BootP column.  
If an IP address is not currently in use, these actions take effect immediately. If an  
IP address is currently in use, these actions take effect only after the switch is reset  
or power cycled.

BootP When Needed  
Allows the switch to request an IP address if one has not already been set from the  
console terminal.  
When selected, this mode operates as follows:  
When the IP data is entered from the console terminal, the data becomes the  
in-band address of the switch and BootP requests are not broadcast. The  
switch can be managed using this in-band IP address.  
When the in-band IP address is not set from the console terminal, the switch  
broadcasts BootP requests until it receives a BootP reply containing an IP  
address. If the switch does not receive a BootP reply that contains an IP  
address, the switch cannot be managed in-band.  
If an IP address is not currently in use, these actions take effect immediately. If an  
IP address is currently in use, these actions take effect only after the switch is reset  
or power cycled.  
BootP Always  
Allows the switch to be managed only when configured with the IP address  
obtained from the BootP server.  
When selected, this mode operates as follows:  
The switch continues to broadcast BootP requests, regardless of whether an  
in-band IP address is set from the console terminal.  
If the switch receives a BootP reply that contains an in-band IP address, the  
switch uses this new in-band IP address.  
If the switch does not receive a BootP reply, the switch cannot be managed  
using the in-band IP address set from the console terminal.  
If an IP address is not currently in use, these actions take effect immediately. If an  
IP address is currently in use, these actions take effect only after the switch is reset  
or power cycled.

Using the Console Interface  
Port List Syntax  
When you enter a port list in a stack configuration, you must specify either a  
unit/port number list, NONE, or ALL. In a stack configuration, ALL indicates all  
of the stack ports; in a standalone switch, ALL indicates all of the switch ports.  
Note: NONE and ALL must be entered in uppercase characters as shown in  
the screen prompt.  
A unit/port number list is composed of one or more list items, each of which can  
be a single number or a range of numbers (where the number represents one or  
more ports). If a list item is preceded by a number and then a slash (/), the number  
represents a stack unit.  
For example, 1/1-7,2/1-7,2/9,3/1-4,4/12 is a valid unit/port number list (see entry  
S1 in Figure 3-13 on page 3-32).  
It represents the following port order:  
Unit 1: ports 1 to 7  
Unit 2: ports 1 to 7 and port 9  
Unit 3: ports 1 to 4  
Unit 4: port 12.  
See Accelerator Keys for Repetitive Tasksfollowing this section for more  
information about creating port lists.  
Accelerator Keys for Repetitive Tasks  
You can use certain keystrokes as accelerator keysto help speed up repetitive  
tasks. For example, suppose you want to modify the Port List field in the MAC  
Address Security Port List screen (Figure 3-13 on page 3-32). You can modify the  
port list in any of the following ways:

Adding a New Port to an Existing Port Number List:  
In the example shown in Figure 3-13 on page 3-32, S3 shows the Port List field  
values as:  
1/3,2/7,3/1-4  
If you want to add another port (for example, port 2/9) to the existing port number  
list, you could highlight the field and then type another port list, including the new  
port number: 1/3,2/7,2/9, 3/1-4 [Enter].  
This works but is quite time consuming.  
Instead, you can highlight the field, and then enter +2/9 [Enter]. The existing field  
keeps the previous list, and adds the new port number (2/9) between ports  
2/7 and 3/14.  
(If you had chosen to add port 2/8 to the existing port number list, the field accepts  
the new port 2/8 but shows the new port number list field as: 1/3,2/7-8,3/1-4.)  
Removing a Port from an Existing Port Number List:  
To remove a port from the port number list, use the minus sign (-) character  
instead of the plus sign (+) character as described above.  
Copying an Existing Field into an Adjacent Field:  
You can use the period (.) character to copy a previously entered field value into  
the field directly next to it. For example, to copy the Allowed Source S3 (shown in  
Figure 3-15 on page 3-36) into the next field (entry 6):  
1. Enter a MAC address into the next MAC Address field.  
2. Highlight the (blank) Allowed Source field.  
3. Enter the period character (.) and press [Enter].  
The port number list from the previous entry is copied into the new field.

MAC Address Security Table  
The MAC Address Security Table screen allows you to specify the ports that each  
MAC address is allowed to access. You must also include the MAC addresses of  
any routers and switches that are connected to any secure ports.  
There are 16 available MAC Address Security Table screens you can use to create  
as many as 448 MAC address entries. Twenty-eight MAC address entries are  
displayed on each screen (see Figure 3-14).

Find an Address  
Allows you to search for a specific MAC address that is used in any of the  
MAC Address Security Table screens.  
MAC Address  
Allows you to specify up to 448 MAC addresses that are authorized to access  
the switch. You can specify the ports that each MAC address is allowed to  
access using the Allowed Source field (see next field description). The  
specified MAC address does not take effect until the Allowed Source field is  
set to some value (a single unit/port number or a port list value that you  
previously configured in the MAC Address Security Port Lists screen). You can  
clear an existing MAC address field by entering zero (0) in the field and  
pressing [Enter].  
Default  
Range

A range of 6 Hex Octets, separated by dashes (multicast1 and  
broadcast addresses are not allowed).  
Allowed Source  
Allows you to specify the ports that each MAC address is allowed to access.  
The options for the Allowed Source field include a single unit/port number or a  
port list value that you have previously configured in the MAC Address  
Security Port Lists screen.  
Default  
Range  
- (Blank field)  
A single unit/port or a port list value (for example, 1/3, 1/6,  
3/4, S1, S5, etc.).  
1 Multicast address -- Note that the first octet of any Multicast address will always be an odd number.

Using the BayStack 410-24T 10BASE-T Switch  
VLAN Configuration Menu  
The VLAN Configuration Menu screen (Figure 3-16) allows you to select the  
appropriate screen to configure up to 64 VLANs (VLAN 1 is port-based, by  
default). You can configure as many as 63 protocol-based VLANs, with up to 15  
different protocols. The number of different protocols you can configure depends  
on the number of hexidecimal values (PID values) associated with the protocol  
page 3-44).  
Note: The BayStack 410-24T switch ports do not have the ability to assign  
incoming untagged frames to a protocol-based VLAN (see Gigabit Ports and  
BayStack 410-24T Switch Ports Restrictionon page 3-46).  
When you create VLANs, you can assign various ports (and therefore the devices  
attached to these ports) to different broadcast domains. Creating VLANs increases  
network flexibility by allowing you to reassign devices to accommodate network  
moves, additions, and changes, eliminating the need to change physical cabling.  
See IEEE 802.1Q VLAN Workgroupson page 1-36 for detailed information  
about configuring VLANs.  
Choose VLAN Configuration (or press v) from the Switch Configuration Menu  
screen to open the VLAN Configuration Menu.

Using the BayStack 410-24T 10BASE-T Switch  
VLAN Configuration  
The VLAN Configuration screen (Figure 3-17) allows you to assign VLAN port  
memberships to standalone or stacked unit ports. You can also create port-based  
VLANs and protocol-based VLANs:  
Port-based VLANs allow you to explicitly configure switch ports as VLAN  
port members.  
Protocol-based VLANs allow you to configure your switch ports as members  
of a broadcast domain, based on the protocol information within a packet.  
Protocol-based VLANs can localize broadcast traffic and assure that only the  
protocol-based VLAN ports are flooded with the specified protocol-type  
packets.  
When you configure ports as VLAN port members, they become part of a set of  
ports that form a broadcast domain for a specific VLAN. You can assign switch  
ports, whether standalone or stacked unit ports, as VLAN port members of one or  
more VLANs.  
You can assign VLAN port members attributes that allow the individual ports to  
operate in accordance with the IEEE 802.1Q tagging rules. You can define each of  
the VLAN port members as tagged or untagged (see IEEE 802.1Q Taggingon  
page 1-37 for a description of important terms used with 802.1Q VLANs).  
You can also use this screen to create and to delete specific VLANs, to assign  
VLAN names, and to assign any VLAN as the management VLAN.  
Choose VLAN Configuration (or press v) from the VLAN Configuration Menu  
screen to open the VLAN Configuration screen.

VLAN Configuration Screen Fields (continued)  
Field  
Description  
User-defined PID  
Allows you to create your own user-defined protocol-based VLAN where you specify  
the Protocol Identifier (PID) for the VLAN. To set this field, the VLAN State field must  
be set to Inactive (some restrictions apply, see User-Defined Protocol Identifier  
(PID) Descriptionon page 3-45).  
Default  
Range  
0x0000  
Any 4-bit hexadecimal value (for example, 0xABCD)  
VLAN State  
Allows you to activate your newly created VLAN.  
The following associated field values: VLAN Type, Protocol Id (PID), and  
User-defined PID must be configured appropriately before this field can be set to  
Active.  
After you set the VLAN State field value to Active, you cannot change the VLAN  
Type, Protocol Id, or User-defined PID field values, unless you delete the VLAN.  
If you delete a VLAN, all configuration parameters that are associated with that  
VLAN are deleted also.  
Default  
Range  
Inactive  
Inactive, Active  
Port Membership  
Allows you to assign VLAN port memberships to standalone or stacked unit ports.  
The ports can be configured in one or more VLANs. To set this field, you must Set  
the VLAN State field value to Active. Certain restrictions apply for gigabit ports and  
when using the BayStack 410-24T switch ports as participants of Protocol-based  
VLANs (see Gigabit Ports and BayStack 410-24T Switch Ports Restrictionon  
page 3-46).  
This field is dependent on the Tagging field value in the VLAN Port Configuration  
screen (see the Tagging field description in Table 3-16 on page 3-47).  
For example:  
When the Tagging field is set to Untagged Access, you can set the Port  
Membership field as an untagged port member (U) or as a non-VLAN port  
member (-).  
When the Tagging field is set to Tagged Trunk, you can set the Port Membership  
field as a tagged port member (T) or as a non-VLAN port  
member (-).  
The Port Membership fields are displayed in six-port groups (for example, 1-6, 7-12,  
13-18). The number of ports displayed depends on the switch model or type of  
optional MDA installed in the Uplink Module slot.  
Default  
Range  
U (All ports are assigned as untagged members of VLAN 1.)  
U, T, and -

(RARP):  
RARP is a protocol used by some old  
diskless devices to obtain IP addresses by  
providing the MAC layer address. When you  
create a VLAN based on RARP, you can  
limit the RARP broadcasts to the ports that  
lead to the RARP server.

User-Defined Protocol Identifier (PID) Description  
In addition to the standard predefined protocols, user-defined protocol-based  
VLANs are supported. For user-defined protocol-based VLANs, you specify the  
Protocol Identifier (PID) for the VLAN. Any frames that match the specified PID  
in any of the following ways are assigned to that user-defined VLAN:  
The ethertype for Ethernet Type 2 frames  
The PID in Ethernet SNAP frames  
The DSAP or SSAP value in Ethernet 802.2 frames  
The following PIDs (see Table 3-15) are reserved and are not available for

Gigabit Ports and BayStack 410-24T Switch Ports Restriction  
Gigabit ports and the BayStack 410-24T switch ports do not have the ability to  
assign incoming untagged frames to a protocol-based VLAN.  
To allow Gigabit ports and BayStack 410-24T switch ports to participate in  
protocol-based VLANs, you must set the Tagging field value in the VLAN Port  
Configuration screen to Tagged Trunk.  
VLAN Port Configuration  
The VLAN Port Configuration screen (Figure 3-18) allows you to configure  
specified switch ports with the appropriate PVID/VLAN association that enables  
the creation of VLAN broadcast domains (see Shared Serverson page 1-44 for  
more information about setting up VLAN broadcast domains).  
You can configure specified switch ports to filter (discard) all received tagged  
frames, untagged frames, or unregistered frames (see IEEE 802.1Q Taggingon  
page 1-37).  
You can also prioritize the order in which the switch forwards packets, on a  
per-port basis (see IEEE 802.1p Prioritizingon page 1-57).  
Choose VLAN Port Configuration (or press c) from the VLAN Configuration  
Menu screen to open the VLAN Port Configuration screen.

Port Configuration  
The Port Configuration screen (Figure 3-21 and Figure 3-22) allows you to  
configure specific switch ports or all switch ports. You can enable or disable the  
port status of specified switch ports, set (optional) MDA ports to autonegotiate for  
the highest available speed of the connected station, and you can set the duplex  
mode for specific ports (autonegotiation is not supported on fiber optic ports).  
You can disable switch ports that are trunk members; however, the screen prompts  
for verification of the request before completing the action. Choosing [Yes]  
disables the port and removes it from the trunk.  
Note: The Autonegotiation fields, the Link Trap, the Speed fields, and the  
Duplex fields are independent of MultiLink trunking, rate limiting, VLANs,  
IGMP Snooping, and the STP.

Choosing a High Speed Flow Control Mode  
The High Speed Flow Control feature allows you to control traffic and avoid  
congestion on the gigabit full-duplex link. If the receive port buffer becomes full,  
the BayStack 410-24T switch issues a flow-control signal to the device at the  
other end of the link to suspend transmission. When the receive buffer is no longer  
full, the switch issues a signal to resume the transmission. You can choose  
Symmetric or Asymmetric flow-control mode:  
Symmetric Mode  
This mode allows both the gigabit MDA port and its link partner to send  
flow-control pause frames to each other. When a pause frame is received (by  
either the gigabit MDA port or its link partner), the port suspends transmission of  
frames for a number of slot times specified in the control frame or until a  
pause-release control frame is received. Both devices on the link must support this  
mode when it is selected.

Using the Console Interface  
Asymmetric  
This mode allows the link partner to send flow control pause frames to the gigabit  
MDA port. When a pause frame is received, the receiving port suspends  
transmission of frames for a number of slot times specified in the control frame or  
until a pause-release control frame is received.  
In this mode the gigabit MDA port is disabled from transmitting pause frames to  
its link partner. Use this mode when the gigabit MDA port is connected to a  
buffered repeater device.  
MultiLink Trunk Configuration  
The MultiLink Trunk Configuration Menu screen (Figure 3-24) allows you to  
select the appropriate screen to configure up to six MultiLink trunks (you can  
group up to four switch ports together to form each trunk).  
You can configure up to six MultiLink trunks in each stack, with trunk members in  
either a single unit or distributed between units within the stack configuration  
(distributed trunking).  
You can monitor the bandwidth usage for the trunk member ports within each  
trunk. For more information about configuring MultiLink Trunks, see MultiLink  
Trunkson page 1-61.  
Note: When a trunk is not active (Trunk Status field set to Disabled),  
configuration changes do not take effect until you set the Trunk Status field to  
Enabled.

The MultiLink Trunk Configuration screen (Figure 3-25) allows you to configure  
up to six trunks in a standalone switch or stack. In a stack configuration, trunk  
members can be distributed between any of the units within the same stack  
configuration.  
Any mix of up to eight BayStack 410-24T switches and BayStack 450 switches  
can be stacked to provide a total of 224 ports (when all MDA slots are configured  
with the maximum port availability).  
Figure 3-25 shows six trunks in a stack configuration:  
Trunk 1 has four trunk members in unit 3.  
Trunks 2, 3, 4, and 5 each have two trunk members in individual units.  
Trunk 6 has four trunk members distributed into four separate units of the  
stack.  
When the trunks are enabled, the trunk members take on default settings necessary  
for correct operation of the MultiLink Trunking feature. These default settings can  
affect the correct operation of your configured network. If you disable a trunk, you  
may need to reconfigure the specific trunk members switch ports to return to the  
previous switch configuration. See MultiLink Trunkson page 1-64 for more  
information.  
Choose Trunk Configuration (or press t) from the MultiLink Trunk Configuration  
Menu screen to open the MultiLink Trunk Configuration screen.

Trunk  
Column header for the read-only fields in this screen. The read-only data displayed in the  
Trunk column indicates the trunk (1 to 6) that corresponds to the switch ports specified in  
the user-configurable Trunk Members fields.  
Trunk Members The Trunk Members column contains fields in each row that can be configured to create  
(Unit/Port)  
the corresponding trunk. The Unit value in the (Unit/Port) field is configurable only when  
the switch (unit) is part of a stack configuration. It indicates that the trunk members in  
this row are associated with the specified unit number configured in the Unit field. Each  
switch port can only be a member of a single trunk. The appropriate trunk number for  
each trunk member configured within this field is shown adjacent to the corresponding  
switch port in the following screens: Port Configuration screen, and Spanning Tree  
Configuration screen.

Field  
Description  
STP Learning  
The STP Learning column contains a single field for each row that, when enabled, allows  
the specified trunk to participate in the spanning tree. This setting overrides those of the  
individual trunk members.  
Fast is the same as Normal, except that the state transition timer is shortened to two  
seconds.  
Default Value  
Range  
Normal  
Normal, Fast, Disabled  
Trunk Mode  
The Trunk Mode column contains a single read-only field for each row that indicates the  
default operating mode for the switch.  
Basic: Basic mode is the default mode for the switch. When in this mode, source MAC  
addresses are dynamically assigned to specific trunk members for flooding and  
forwarding. This allows the switch to stabilize and distribute the data streams of source  
addresses across the trunk members.  
Trunk Status  
Trunk Name  
The Trunk Status column contains a single field for each row that allows users to enable  
or disable any of the trunks.  
Default Value  
Range  
Disabled  
Enabled, Disabled  
The Trunk Name column contains a single optional field in each row that can be used to  
assign names to the corresponding configured trunks. The names chosen for this  
example can provide meaningful information to the user (for example, S1:T1 to FS2  
indicates Trunk 1 in switch S1 connects to File Server 2).  
MultiLink Trunk Utilization Screen  
The MultiLink Trunk Utilization screen (Figure 3-26 and Figure 3-27) allows you  
to monitor the percentage of bandwidth used by configured trunk members. You  
can choose the type of traffic to monitor.  
Figure 3-26 shows an example of bandwidth utilization rates for the trunk member  
ports configured in Figure 3-25. Because two screens are required to show all of  
the configured trunks (up to six), the screen prompts users to Press [Ctrl]-N to  
view trunks five and six.  
Choose MultiLink Trunk Utilization (or press u) from the MultiLink Trunk  
Configuration Menu screen to open the MultiLink Trunk Utilization screen.

Static Router Ports Allows you to assign switch ports to receive all IP multicast-related traffic. When the  
unit is part of a stack configuration, the screen displays the unit numbers of the  
switches configured in the stack, along with the corresponding ports.  
The configured ports do not filter any IP multicast traffic. The Static Router Ports  
fields are displayed in six-port groups (for example, 1-6, 7-12, 13-18). The number  
of ports displayed depends on the switch model or type of optional MDA that is  
installed in the Uplink Module slot.  
This field affects all VLANs (for example, if you assign a port as a static router port in  
this screen, the port becomes a static router port for the VLAN specified in the  
screens VLAN field, and also for any other VLAN where this port is a member).  
See also Configuring Ports as Static Router Portsfollowing this table.  
Default Value

Configuring Ports as Static Router Ports  
If you specify a port as a Static Router Port in the IGMP Configuration screen,  
that port will receive all the IP Multicast-related information (such as, Host  
Membership Report, Host Membership Query, and IP Multicast UDP data).  
This feature is provided for certain legacy routers that are unable to  
periodically generate a Host Membership Query. If you configure a port as a  
static router port, the IP Multicast traffic can still be forwarded to any  
dynamically detected IGMP routers.

Using the BayStack 410-24T 10BASE-T Switch  
If you are absolutely sure that it is required for your particular legacy router,  
configure only the ports that are towards the legacy router as the static router  
ports. This action will avoid misconfigurations which can prevent you from  
receiving IGMP multicast traffic.  
Note: In most cases, configuring ports as Static Router Ports is not necessary  
and can prevent you from receiving IGMP multicast traffic. You should  
configure a static router port only if you are certain that it is required for your  
particular router. Most routers will be dynamically detected as IGMP routers,  
in which case no configuration is required.  
Multicast Group Membership  
The Multicast Group Membership screen allows you to view configured IP  
multicast group addresses for specific VLANs. The screen displays the IP  
multicast group addresses associated with ports that are configured within a  
standalone switch or a stack of switches.  
Note: The Multicast Group Membership screen will not display any entries if  
the Snooping field value is set to Disabled in the IGMP Configuration screen  
(see IGMP Configurationon page 3-72).  
The displayed addresses are dynamic and can change as clients join, or leave, the  
various IP multicast groups. You can view changes by refreshing the screen (press  
[Ctrl]-P to refresh the screen).  
Choose Display Multicast Group Membership (or press d) from the IGMP  
Configuration Menu screen to open the Multicast Group Membership screen.

Port Statistics  
The Port Statistics screen (Figure 3-34) allows you to view detailed information  
about any switch port in a stacked or standalone configuration. The screen is  
divided into two sections (Received and Transmitted) so that you can compare and  
evaluate throughput or other port parameters. All screen data is updated  
approximately every 2 seconds.  
You can use the Port Statistics screen to clear (reset to zero) port counters for a  
specific port. Alternatively, you can use the Clear All Port Statistics option to clear  
port counters for all ports (see Switch Configurationon page 3-18).  
Choose Display Port Statistics (or press d) from the Switch Configuration Menu

Participation  
Allows you to configure any (or all) of the switch ports for Spanning tree participation.  
When an individual port is a trunk member (see Trunk field), changing this setting for one  
of the trunk members changes the setting for all members of that trunk. You should  
consider how this can change your network topology before you change this setting (see  
MultiLink Trunking Configuration Ruleson page 1-73).

Normal Learning, Fast Learning, Disabled  
Priority  
This read-only field is a bridge spanning tree parameter that prioritizes the ports lowest  
path cost to the root. When one or more ports have the same path cost, the STA selects  
the path with the highest priority (lowest numerical value). See also Path Cost.  
Default Value  
Range

Path Cost  
This read-only field is a bridge spanning tree parameter that determines the lowest path  
cost to the root.  
Default Value  
10 or 100  
Path Cost = 1000/LAN speed (in Mb/s)  
The higher the LAN speed, the lower the path cost.  
See also Priority.  
Range  
1 to 65535  
State  
This read-only field indicates the current port state within the spanning tree network.  
Each port can transition to various states, as determined by the Participation field setting.  
For example, when the Participation field is set to Disabled, the port does not participate  
in the STA and transitions to the Forwarding state (the default). When the Participation  
field is set to Enabled, the port transitions from the Disabled state through the Blocking,  
Listening, and Learning states before entering the Forwarding state.  
Default Value  
Range

Using the BayStack 410-24T 10BASE-T Switch  
A configuration file obtained from a standalone switch can only be used to  
configure other standalone switches that have the same firmware revision and  
model type as the donor standalone switch.  
A configuration file obtained from a stack unit can only be used to configure  
other stacks that have the same number of switches, firmware version, model  
types, and physical IDs as the stack the donor stack unit resides in.  
Reconfigured stacks are configured according to the unit order number of the  
donor unit. For example, the configuration file parameters from a donor unit  
with physical ID x are used to reconfigure the unit with physical ID x.  
The configuration file also duplicates any settings that exist for any MDA that  
is installed in the donor switch.  
If you use the configuration file to configure another switch that has the same  
MDA model installed, the configuration file settings will also apply to and  
override the existing MDA settings.

Troubleshooting  
This chapter describes how to isolate and diagnose problems with your  
BayStack 410-24T switch.  
This chapter covers the following topics:  
Interpreting the LEDs  
Diagnosing and correcting the problem  
-- Normal power-up sequence  
-- Port connection problems  
Software download error codes  
The chapter topics lead you through a logical process for troubleshooting the  
BayStack 410-24T switch. For example, because LEDs provide visual indications  
of certain problems, refer to Interpreting the LEDson page 4-2 to understand  
the various states (see Table 4-1) that your switch LEDs can exhibit during normal  
operation.  
For more help in determining the problem, Diagnosing and Correcting the  
Problemon page 4-4 describes symptoms and corrective actions (see Table 4-2)  
you can perform to resolve specific problems. Subsequent sections give  
step-by-step procedures to correct the problems.

the BayStack 410-24T switch (disconnect and then reconnect the AC power cord);  
then, verify that the switch follows the normal power-up sequence.  
Warning: To avoid bodily injury from hazardous electrical current, never  
remove the top cover of the device. There are no user-serviceable components

Normal Power-Up Sequence  
In a normal power-up sequence, the LEDs appear as follows:  
1. After power is applied to the switch, the Pwr (Power) LED turns on within 5  
seconds.  
2. The switch initiates a self-test, during which the port LEDs display various  
patterns to indicate the progress of the self-test.  
3. Upon successful completion of the self-test (within 10 seconds after power is  
applied), the Status LED turns on.  
4. The remaining port LEDs indicate their operational status, as described in  
Table 4-2.

Port Connection Problems  
You can usually trace port connection problems to either a poor cable connection  
or an improper connection of the port cables at either end of the link. To remedy  
these types of problems, make sure that the cable connections are secure and that  
the cables connect to the correct ports at both ends of the link.  
Port connection problems are also traceable to the autonegotiation mode or the  
port interface.

Troubleshooting  
Autonegotiation Modes  
Port connection problems can occur when a port is connected to a station that is  
not operating in a compatible mode (for example, connecting a full-duplex port to  
a half-duplex port). The BayStack 410-24T switch negotiates port speeds  
according to the IEEE 802.3u autonegotiating standard. The switch adjusts  
(autonegotiates) the port speed and duplex mode to match the best service  
provided by the connected station, up to 100 Mb/s in full-duplex mode with an  
optional 100BASE-T MDA installed.  
If the connected station uses a form of autonegotiation that is not compatible  
with the IEEE 802.3u autonegotiating standard, the BayStack 410-24T switch  
cannot negotiate a compatible mode for correct operation.  
If the autonegotiation feature is not present or not enabled at the connected  
station, the BayStack 410-24T switch may not be able to determine the correct  
duplex mode.  
In both situations, the BayStack 410-24T switch autosensesthe speed of the  
connected station and, by default, reverts to half-duplex mode. If the connected  
station is operating in full-duplex mode, it cannot communicate with the switch.  
To correct this mode mismatch problem:  
1. Use the Port Configuration screen to disable autonegotiation for the  
suspect port (see Port Configurationon page 3-52).  
2. Manually set the Speed/Duplex field to match the speed/duplex mode of  
the connected station (see Table 3-19 on page 3-53).  
You may have to try several settings before you find the correct speed/duplex  
mode of the connected station.  
If the problem persists:  
1. Disable the autonegotiation feature at the connected station.  
2. Manually set the speed/duplex mode of the connected station to the same  
speed/duplex mode you have manually set for the BayStack 410-24T  
switch port.  
Port Interface  
Ensure that the devices are connected using the appropriate crossover or  
straight-through cable (see Appendix D, Connectors and Pin Assignments).

Media Dependent Adapters  
The RJ-45 ports are configured as media-dependent interface-crossover (MDI-X)  
connectors. These ports connect over straight cables to the network interface  
controller (NIC) card in a node or server, similar to a conventional Ethernet  
repeater hub. If you are connecting to another Ethernet hub or Ethernet switch,  
you need a crossover cable unless an MDI connection exists on the associated port  
of the attached device.  
The 400-4TX MDA can operate at either 10 Mb/s or 100 Mb/s. The speed is  
determined through autonegotiation with its connecting device.  
For installation instructions, see Installing an MDAon page B-6.  
100BASE-FX MDAs  
Warning: Fiber optic equipment can emit laser or infrared light that can  
injure your eyes. Never look into an optical fiber or connector port. Always

Using the BayStack 410-24T 10BASE-T Switch  
Installing an MDA  
The Uplink Module slot on the BayStack 450 switches accommodates a single  
MDA. The connection can be either a 10/100BASE-TX MDA with an RJ-45  
connector or a (fiber) 100BASE-FX MDA with an SC or MT-RJ connector.  
Note: The MDA is not hot-swappable. Power down the switch before  
installing or removing an MDA.  
To install an MDA into the Uplink Module slot:  
1. Unplug the AC power cord from the back of the switch.  
2. Loosen the thumb screws and remove the filler panel (or previously  
installed MDA) from the Uplink Module slot.  
Note: If you are replacing an installed MDA with another type of MDA, see  
Replacing an MDA with a Different Modelon page B-7.  
3. Insert the MDA into the Uplink Module slot guides (Figure B-3).  
Make sure the MDA slides in on the guides provided. Failure to align the  
guides could result in bent and broken pins  
BS41048A

Connectors and Pin Assignments  
This appendix describes the BayStack 410-24T switch port connectors and pin  
assignments.  
RJ-45 (10BASE-T/100BASE-TX) Port Connectors  
The RJ-45 port connectors (Figure D-1) are wired as MDI-X ports to connect end  
stations without using crossover cables. (See MDI and MDI-X Deviceson  
page D-2 for information about MDI-X ports.)  
For 10BASE-T connections, use Category 3 (or higher) UTP cable. When using  
10BASE-T/100BASE-TX MDAs, use only Category 5 UTP cable.

MDI and MDI-X Devices  
Media dependent interface (MDI) is the IEEE standard for the interface to  
unshielded twisted pair (UTP) cable.  
For two devices to communicate, the transmitter of one device must connect to the  
receiver of the other device. The connection is established through a crossover  
function, which can be a crossover cable or a port that implements the crossover  
function internally.  
Ports that implement the crossover function internally are known as MDI-X ports,  
where X refers to the crossover function.  
Note: For the transmitter of one device to connect to the receiver of another  
device, the total number of crossovers must always be an odd number.  
The following sections describe the use of straight-through and crossover cables  
for connecting MDI and MDI-X devices.

Appendix F  
Sample BootP Configuration File  
This appendix provides a sample BootP configuration file. The BootP server  
searches for this file, called bootptab (or BOOTPTAB.TXT, depending on your  
operating system), which contains the site-specific information (including IP  
addresses) needed to perform the software download and configuration. You can  
modify this sample BootP configuration file or create one of your own.  
A sample BootP configuration file follows:  
# The following is a sample of a BootP configuration file that was extracted  
# from a Bay Networks EZ LAN network management application. Note that other  
# BootP daemons can use a configuration file with a different format.  
#
# Before using your switch BootP facility, you must customize your BootP  
# configuration file with the appropriate data.  
#
# Blank lines and lines beginning with '#' are ignored.  
#
# Legend:  
#
#
#
first field -- hostname  
ht -- hardware type  
#
#
#
ha -- host hardware address  
tc -- template host (points to similar host entry)  
ip -- host IP address  
#
#
hd -- bootfile home directory  
bf -- bootfile  
# EZ  
# EZ  
# EZ  
#
dt -- device type  
fv -- firmware version  
av -- agent version  
# Fields are separated with a pipe (|) symbol. Forward slashes (/) are  
# required to indicate that an entry is continued to the next line.

Using the BayStack 410-24T 10BASE-T Switch  
# Caution  
#
#
#
#
#
#
Omitting a Forward slash (/) when the entry is continued to the next  
line, can cause the interruption of the booting process or the  
incorrect image file to download. Always include forward slashes  
where needed.  
# Important Note:  
#
#
#
#
#
#
#
If a leading zero (0) is used in the IP address it is calculated as an  
octal number. If the leading character is "x" (upper or lower case),  
it is calculated as a hexadecimal number. For example, if an IP address  
with a base 10 number of 45 is written as .045 in the BOOTPTAB.TXT file,  
the Bootp protocol assigns .037 to the client.  
# Global entries are defined that specify the parameters used by every device.  
# Note that hardware type (ht) is specified first in the global entry.  
#
# The following global entry is defined for an Ethernet device. Note that this  
# is where a client's subnet mask (sm) and default gateway (gw) are defined.  
#
global1|/  
|ht=ethernet|/  
|hd=c:\opt\images|/  
|sm=255.255.255.0|/  
|gw=192.0.1.0|

# The following sample entry describes a BootP client:
