26 Ethernet Routing Switch 2500 Series hardware
The Console port is a DB-9, RS-232-D male serial port connector. You can
use this connector to connect a management station, console, or terminal to
the Ethernet Routing Switch 2500 Series by using a straight-through DB-9
to DB-9 standard serial port cable. You must use a VT100/ANSI-compatible
terminal (for cursor control and to activate cursor and functions keys) to
use the Console port.
The default settings of the Console port are:
•
•
•
•
9600 baud with eight data bits
one stop bit
no parity as the communications format
flow control set to disabled
Gigabit Interface Converter
Small Form Factor Pluggable Gigabit Interface Converters are
hot-swappable input and output enhancement components designed for
use with Nortel products to allow Gigabit Ethernet ports to link with fiber
optic networks.
SFP GBIC Support on the Ethernet Routing Switch 2500 Series
Small Form Factor Pluggable (SFP) transceivers are hot-swappable
input/output enhancement components designed for use with Nortel
products to allow Gigabit Ethernet ports to link with other Gigabit Ethernet
ports over various media types.
The Ethernet Routing Switch 2500 Series supports the following SFPs:
•
•
•
•
1000Base-SX SFP GBIC (mini-GBIC, connector type: LC)
1000Base-SX SFP GBIC (mini-GBIC, connector type: MT-RJ)
1000Base-LX SFP GBIC (mini-GBIC, connector type: LC)
CWDM SFPs
For more information about the SFP GBICs see Installing Gigabit Interface
Converters, SFPs, and CWDM SFP Gigabit Interface Converters (312865).
Port connectors
The Ethernet Routing Switch 2500 Series uses 10BASE-T/100BASE-TX
RJ-45 (8-pin modular) port connectors.
The Ethernet Routing Switch 2500 Series uses autosensing ports
designed to operate at 10 Mb/s (megabits per second) or at 100 Mb/s,
depending on the connecting device. These ports support the IEEE 802.3u
autonegotiation standard, which means that when a port is connected
to another device that also supports the IEEE 802.3u standard, the two
devices negotiate the best speed and duplex mode.

Hardware components of the Ethernet Routing Switch 2500 Series 27
The 10BASE-T/100BASE-TX switch ports also support half- and full-duplex
mode operation.
The 10BASE-T/100BASE-TX RJ-45 switch ports can connect to 10 Mb/s or
100 Mb/s Ethernet segments or nodes.
ATTENTION
Use only Category 5 copper Unshielded Twisted Pair (UTP) cable connections
when connecting 10BASE-T/100BASE-TX ports.
Auto-MDI/MDI-X
The 10/100BASE-TX port connectors support auto-MDI/MDI-X.
Typical MDI-X ports connect over straight-through cables to the Network
Interface Card (NIC) in a node or server, similar to a conventional Ethernet
repeater hub. However, with the auto-MDI/MDI-X feature, you can still use
straight-through cables while connecting to an Ethernet hub or switch.
The auto-MDI/MDI-X feature is dependent on the autonegotiation feature.
If autonegotiation is enabled on a port, the auto-MDI/MDI-X feature is
automatically enabled on the port as well. If autonegotiation is disabled on a
port, then the port operates as a standard MDI-X port.
Power over Ethernet on Ethernet Routing Switch 2526T-PWR
and 2550T-PWR
The Ethernet Routing Switch 2526T-PWR and 2550T-PWR provide IEEE
802.3af-compliant power over the PoE-labeled front-panel RJ-45 ports. The
switches provide power discovery and power management on each port
basis. You can use the PoE ports to provide power to network appliances,
such as IP Phones, wireless access points, and video devices.
You can enable or disable power to individual ports. For information about
configuring PoE, see "Power over Ethernet for the Ethernet Routing Switch

Nortel Ethernet Routing Switch 2500
Series stacking
This chapter includes information about the stacking features, such as stack
capabilities, stacking functionality delivery, stack configuration, and Auto Unit
Replacement. This chapter contains information about the following topics:
•

•
Stacking capabilities
The Nortel Ethernet Routing Switch 2500 Series contain two built-in rear
ports that can be used as stacking/cascade ports to enable a stack of up to
eight units.
A stack can consist of Nortel Ethernet Routing Switch 2526T, Nortel Ethernet
Routing Switch 2550T, Nortel Ethernet Routing Switch 2526T-PWR, and
Nortel Ethernet Routing Switch 2550T-PWR units.
The stack ports on ERS 2500 series switches provide 4Gbps (FDX) stack
bandwidth for an aggregate of up to 32Gbps for a stack of eight units.
A stack of Ethernet Routing Switch 2500 series switches can also consist of
a mix of stack pre-enabled units as well as non pre-enabled units. The non
pre-enabled units in a stack must meet the following requirements before
they are added into a stack configuration:
•
contain a valid license file (a license file contains the switch MAC
addresses)
•
Operational mode of rear ports operating in Stacking Mode

Stacking functionality delivery
The Nortel Ethernet Routing Switch 2500 series switches allow you to
stack multiple switches together to create a single virtual switch that can
be managed as a single device. Stacking functionality is delivered in
two distinctively different ways on Ethernet Routing Switch 2500 series
switches:
•
•
Through stack enabled units with order codes AL2515xxx-E6. The
rear ports of stack enabled ERS 2500 switch are factory pre-enabled,
configured, and operating in Stacking Mode by default and are ready
to stack. These units do not require or use the software licensing
mechanism.
Through software using a licensing mechanism for standalone units with
order codes AL2500xxx-E6. Standalone ERS 2500 switches require the
purchase of a Stacking License Kit for each license to create a license
file, which unlocks stacking capability on standalone units.
Stack enabled switches
The stack enabled unit rear ports are configured in Stacking Mode at
the factory and are ready for immediate use for connection in a stack
configuration. Stacking Mode is the default operating mode that cannot be
overridden by a factory default. Standalone Mode operation is still available
for configuration on the rear-ports of stack enabled units. For information
on adding or replacing a new unit, see "Adding/Replacing a stack unit"
All factory pre-enabled units are identifiable through CLI, Web UI, and
Device Manager with the text Stack Enabled included in the switch
description for identification purposes.
Standalone configuration with license files
Standalone units are not pre-enabled with stacking capability in the factory
and require the use of a software based licensing mechanism to unlock
stacking functionality for activation on the rear ports. Standalone units use
the GenLic engine for decryption of a license file. The license file must
contain the switch MAC address to unlock the stacking functionality.
Standalone units require the purchase of an Ethernet Routing Switch 2500
series Stacking License Kit, of which there are four types available. Each kit
contains a License Certificate with a License Authorization Code (LAC) that
enables a specific number of stacking licenses for one or multiple ERS 2500
series switches. Each ERS 2500 series switch requires one license file to
unlock stacking functionality. A single license file can contain up to 1000
switch MAC addresses for installation on multiple switches.

A Stacking License Certificate contains instructions on how to deposit
license entitlements into a license bank, enter switch MAC address(es),
create the license file, then download and copy the license file onto each
switch requiring stacking functionality. These instructions are carried out on
ATTENTION
Once a valid license file is downloaded on to an Nortel Ethernet Routing Switch
2500 Series switch, you can configure the operational mode of rear ports to
Stacking Mode. Although the rear ports are set to Stacking Mode, a reboot of the
switch is required to fully enable the stacking operation.
Working with license files using the CLI
With the following commands, you can copy the license file to your switch
and display or clear the existing license information:
•
•
•
copy tftp license command The copy tftp license command
copies the license file from a TFTP server to your switch. After you copy the
license to the switch, you need to perform a reboot to activate the license.
ATTENTION
The license is copied to NVRAM. If you reset the switch to default, this removes
the license from the switch. But the stacking feature is enabled until you configure
the switch to Standalone Mode.
The syntax for the copy tftp license command is:
copy tftp license <A.B.C.D> <WORD>
The copy tftp license command is executed in the Privileged EXEC
command mode.
"copy tftp license command parameters" (page 41) describes the
parameters and variables for the copy tftp license command.

48 Nortel Ethernet Routing Switch 2500 Series stacking
Cascade Down port
The Cascade Down port is used to connect this switch unit to the next unit
in the stack through a stack cable. A connection from this port must be
attached to the Cascade Up port of the next switch in the stack. A return
cable from the Cascade Down port of the last unit must be connected to
the Cascade Up port of the first unit to complete the stack connection.
ATTENTION
Each Nortel Ethernet Routing Switch 2500 series switch is supplied with one
46-cm stack cable to create a stack connection. For stacking three or more units
(maximum 8 units per stack), you need to order the 1.5 or 3 meters stack return
cable (order number AL2518002-E6 and AL2518003-E6, respectively).
Cascade Up port
The Cascade Up port is used to accept a stack cable connection from
an adjacent unit above. A return cable from the Cascade Up port of the
first unit must be connected to the Cascade Down port of the last unit to
complete a stack connection.
ATTENTION
Nortel Ethernet Routing Switch 2500 series switches use tested and certified
Category 5E UTP cables as stack cables. All Nortel branded ERS 2500 series
stack cables are for use with these switches. However, Cat 5E stack cable
connections of up to 100 meters is possible between each ERS 2500 switch but
not officially supported. Using non-Nortel tested and certified stack cables for
such configurations are solely the user’s responsibility should any stack operation
issues occur.
The following illustration demonstrates the proper stack cable crossover
configuration. Failure to use this configuration can result in loss of
connectivity. This example shows a cascade down configuration

Stack configuration 49
1. Base Unit
2. Cascade Cable
3. Cascade Cable (used for return)
Initial stack 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.
For example, when the stack is initially powered, the base unit becomes unit
1 and the unit that the base unit connects to (via the Cascade Down 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.
Stack MAC address
When a switch participates in a stack configuration, a stack MAC address is
automatically assigned during stack initialization. The stack MAC address is
the base unit MAC address plus 1. If another unit in the stack is assigned
as the base unit, the new stack MAC address is the MAC address of the
new base unit plus 1. The original stack IP address still applies to the new
base unit.
Stack configurations
Due to stack parameters being associated with the base unit, the physical
stack order depends on the base unit position and whether the stack is
configured cascade up (stack up) or cascade down (stack down). This
designation depends on the stack cabling arrangement.
The system automatically numbers the physical units based on the
designated base unit (Unit 1). In a cascade down configuration, the base
unit is physically located as the top unit in the stack. The cable connected to
the Cascade Down connector of the base unit terminates in the Cascade Up
connector on the next unit in the stack which is physically located below the
base unit. This next unit is designated Unit 2. The stack is wired downward
through the units and the system continues to number in this manner
throughout the stack. In this configuration, the base unit discovers the
stack in a cascade down (stack down) direction. The following illustration
demonstrates a cascade down (stack down) configuration.

ATTENTION
Many network management software packages assume a cascade down (stack
down) configuration, Nortel recommends the usage of this configuration.
Cascade down stack configuration
In a cascade up (stack up) configuration, the base unit is physically
located as the top unit in the stack. The cable connected to the Cascade
Down connector of the base unit terminates in the Cascade Up connector
physically located at the bottom of the stack. This next unit is designated Unit
2. The stack is wired upward through the units and the system continues to
number in this manner throughout the stack. In this configuration, the base
unit discovers the stack in a cascade up (stack up) direction. The following
illustration demonstrates a cascade up (stack up) configuration.

Stack configuration 51
Cascade up stack configuration
Regardless of stack configuration, the following applies:
•
•
•
When power is applied to the stack the base unit initializes, typically
within 60 seconds, and the entire stack powers up as a single logical unit.
A RS-232 communications cable can be attached to the console port of
any switch in the stack to establish a console connection.
A software upgrade can be performed on the stack from any switch using
the console interface, a Telnet session, the web-based management
interface, or any SNMP-based management software.
•
•
The stack can be managed using a Telnet session, web-based
management interface, or any SNMP-based management software
through any stack switch port.
When stacking two or more switches. use the 3 meters cascade
max-return cable (part number AL2518003-E6) to complete the link
from the last unit in the stack to the 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 unit LED display panel moving to a steady
amber state.

52 Nortel Ethernet Routing Switch 2500 Series stacking
This automatic failover is only a temporary safeguard. If the stack
configuration loses power, the temporary base unit cannot power up as
the base unit when power is restored. Also, if the original unit rejoins the
stack, it cannot resume base unit status. For this reason, always assign
the temporary base unit as the base unit until the failed unit is repaired
or replaced.
ATTENTION
If the temporary base unit is not assigned as the new base unit, and the temporary
base unit fails, the next unit in the stack order becomes the temporary base
unit. This process continues after successive failures until only two units are left
in the stack.
Redundant cascade stacking
The Nortel Ethernet Routing Switch 2500 Series allows a stack of up to 8
units into a dual-path cascade stack. If any single unit fails or if a cable is
accidently disconnected, other units in the stack remain operational without
interruption.
In addition to increasing bandwidth, the software uses the cables to provide
two paths between units. If one path breaks the data travels over the
remaining path with half the normal inter-switch bandwidth.
The following diagram shows an example of a stack configuration with a unit
failure in the stack. This illustrates:
•
Unit 3 becomes non-operational due to a unit failure, cable
disconnection, or a loss of power.
•
Units 2 and 4, directly upstream and downstream from Unit 3, sense
the loss of link signals from unit 3. The software causes all the data to
traverse the remaining path.
•
•
The Cascade Down LED for Unit 2 and the Cascade Up LED for Unit 4
turn amber to indicate an error has been detected.
The remaining stack units continue to be connected.

Removing a stack unit
If a unit is removed from the stack, the following switch configuration settings
revert to those configured before the unit became a member of the stack:
•
•
•
IP address
Console, Web, Telnet, and SNMP passwords
SNMP community strings
Adding/Replacing a stack unit
To replace a failed stack unit or insert a new unit into a stack, follow this
procedure:
Step Action
1
2
Upload a copy of the stack configuration file to a TFTP server.
Since unit failure is not a predictable situation, it is suggested that
the stack configuration file is backed up regularly to a TFTP server.
Obtain the new ERS 2500 switch.

Ensure that the new switch is set to factory default values. Then,
if the unit is a standalone ERS 2500 switch, ensure that a valid
stacking license.dat file is installed on the switch and the rear ports
are operating in Stacking Mode. If the unit is a Stack Enabled
ERS 2500 switch, then the unit is ready for adding or replacing.
For information on installing a stacking license, see "Standalone

Download the configuration file to the new unit.
Manually insert the new unit in the stack. Turn off the new unit
inserted into the stack and manually replace the failed unit in the
stack. Plug in the stack cables into the appropriate cascade ports.
Power up the new unit in the stack.
The new unit joins the stack and the configuration of the failed unit is
replicated onto it. Once the replication is completed, the new unit
is reset and rejoins the stack automatically.
—End—
If the base unit is being replaced, remember that the stack elected a
temporary base unit. The new unit cannot automatically resume operation
as the base unit even with the Unit Select switch set to Base. To restore the
stack to its original running state with the new unit set to Base using the
Unit Select switch, the switch stack must be reset.
Auto Unit Replacement
The Auto Unit Replacement (AUR) feature enables users to replace a unit
from a stack while retaining the configuration of the unit. This feature
requires the stack power to be on during the unit replacement.
The main feature of the AUR is the ability to retain the configuration (CFG)
image of a unit in a stack during a unit replacement. The retained CFG
image from the old unit is restored to the new unit. Because retained CFG
images are kept in the DRAM of the stack, the stack power must be kept on
during the procedure.
ATTENTION
In order for AUR to function properly, the new unit and the existing units in the
stack must all be running the same version of software (Release 4.1 software
or later).

Auto Unit Replacement 55
ATTENTION
AUR is intended for a stack configuration of two or more units. In a two-unit stack
configuration, if a unit fails, the remaining unit becomes a standalone switch. AUR
loads the configuration of the failed unit in the replacement of ERS 2500 Series
unit if the failed unit was a non-Base Unit.
AUR is not designed for the situation of removing and reinserting the same switch
(with the same MAC address).
Other information related to this feature:
•
•
•
The new unit must be the same hardware configuration as the old,
including the same number of ports.
If the administrator adds a new unit with a different hardware
configuration, the configuration of this unit is used.
If the administrator adds a new unit with the same hardware
configuration, the previous configuration of the new unit is lost. It is
overwritten with the restored configuration from the stack.
•
•
This feature can be disabled/enabled at any time using the CLI. The
default mode is ENABLE.
Customer log messages are provided.
ATTENTION
After booting a stack, use the CLI command show stack auto-unit-
replacement from a unit console to find out if that unit is ready for replacement.
AUR function
The CFG mirror image is a mirror of a CFG image (in FLASH) of a unit in
a stack. The mirror image does not reside in the same unit with the CFG
image. The unit that contains the CFG image is called the Associated Unit
(AU) of the CFG mirror image. The MAC Address of the AU is called the
Associated Mac Address (AMA) of the CFG mirror image.
An active CFG Mirror Image is a CFG mirror image that has its AU in the
stack. An INACTIVE CFG Mirror Image is a CFG mirror image for which
the associated AU has been removed from the stack. When a CFG mirror
image becomes INACTIVE, the INACTIVE CFG mirror image is copied
to another unit.
The stack always keeps two copies of an INACTIVE CFG mirror image in
the stack in case one unit is removed–the other unit can still provide the
backup INACTIVE CFG mirror image.

CFG mirror image process
The CFG mirror image process is triggered by specific events.
Power Cycle After a power cycle, all the CFG images in a stack are
mirrored.
Figure 15 "CFG mirror process in stack" (page 56) illustrates the CFG mirror
images in a three-unit stack after the stack is powered on. Unit 1 is the
Based Unit (BU) and all other units are Non-Based Units (NBU).
•
•
Unit 1 (BU) contains mirror images for unit 2 (CFG 2) and unit 3 (CFG 3).
Unit 2 (NBU), is the TEMP-BU. It contains a mirror image of unit 1 (CFG
1), in case the BU (unit 1) is removed from the stack.
•
•
•
All three mirror images (CFG 1, CFG 2, and CFG 3) are active.
Unit 2 is the Associated Unit of the CFG 2 mirror image.
The Mac Address 2 is the Associated Mac Address (AMA) of the CFG
2 mirror image.

Auto Unit Replacement 57
Adding a unit In a stack that does not have any INACTIVE CFG mirror
images, adding a new unit causes the CFG image of the new unit to be
mirrored in the stack. For example, in Figure 16 "CFG mirror images in the
stack after adding unit 4" (page 57), after adding unit 4 to the stack, the
CFG 4 mirror image is created in the BU (unit 1).
Figure 16
CFG mirror images in the stack after adding unit 4
Removing an NBU When an NBU is removed from a stack, the related
CFG mirror image in the stack becomes INACTIVE.
The AUR feature ensures that the stack always has two copies of an
INACTIVE CFG mirror image. These two copies must not reside in the
same unit in the stack.
For example, after the removal of unit 4 from the stack shown in Figure 16
mirror image becomes INACTIVE (see Figure 17 "CFG mirror images after
removing unit 4" (page 58)). Another copy of the INACTIVE CFG 4 mirror
image is also created in unit 2.

68 System configuration software features
For information about the security features on the switch, see Nortel
Ethernet Routing Switch 2500 Series Security — Configuration and
Management (NN47215-505).
Autosave feature
By default, every 60 seconds the Ethernet Routing Switch checks whether
a configuration change has occurred, or if a log message is written to
nonvolatile storage. If one of these two events has occurred, the system
automatically saves its configuration and the nonvolatile log to flash memory.
Also, the system automatically saves the configuration file if a system reset
command is invoked by the user.
ATTENTION
Do not power off the switch within 60 seconds of changing any configuration
parameters. Doing so causes loss of changes in the configuration parameters.
You can enable or disable the autosave feature using the autosave enable
and no autosave enable commands.
You can use the CLI command copy config nvram to force a manual save of
the configuration when the autosave feature is disabled.
Using SNTP
The Simple Network Time Protocol (SNTP) feature synchronizes the
Universal Coordinated Time (UTC) to an accuracy within 1 second. This
feature adheres to the IEEE RFC 2030 (MIB is the s5agent). With this
feature, the system can obtain the time from any RFC 2030-compliant
NTP/SNTP server.
ATTENTION
If you have trouble using this feature, try other NTP servers. Some NTP servers
can be overloaded or currently inoperable.
The system attempts to connect to the NTP server at least three times, with
five minutes duration between each retry. If the connection fails after three
attempts, the system waits for the next synchronization time (the default is
24 hours) and begins the process again.
The SNTP provides a real-time timestamp for the software, shown as
Greenwich Mean Time (GMT).
If the SNTP is enabled (the default value is disabled), the system
synchronizes with the configured NTP server at bootup and at
user-configurable periods thereafter (the default sync interval is 24 hours).
The first synchronization is not performed until network connectivity is
established.

force a synchronization.
—End—
Setting local time zone
The SNTP uses Universal Coordinated Time (UTC) for all time
synchronizations so it is not affected by different time zones. For the switch
to report the correct time for your local time zone and daylight savings time,
you must use the following commands:
•
•
•
•
•
•
Using DNS to ping and Telnet
You can use the DNS client to ping or Telnet to a host server or to a host
by name.
To use this feature, you must configure at least one Domain Name Server
(DNS). You can also configure a default domain name. If you configure
a default domain name, that name is appended to host names that do
not contain a dot. The default domain name and addresses are saved in
NVRAM.

BootP automatic IP configuration/MAC address
The Ethernet Routing Switch 2500 Series has a unique 48-bit hardware
address, or MAC address, that is printed on a label on the back panel. You
can use this MAC address when you configure the network BootP server
to recognize the Ethernet Routing Switch 2500 Series BootP requests. A
properly configured BootP server lets the switch automatically learn its
assigned IP address, subnet mask, IP address of the default router (default
gateway), and software image file name.
For more information and an example of a BootP configuration file, see
Choosing a BootP request mode
The BootP Request Mode field in the IP Configuration window lets you
choose which method the switch uses to broadcast BootP requests:
•
•
•
BootP or Default IP
BootP Always
BootP Disabled

BootP or Last Address
ATTENTION
Whenever the switch is broadcasting BootP requests, the BootP process
eventually times out if a reply is not received. When the process times out, the
BootP request mode automatically changes to BootP Disabled mode. To restart
the BootP process, change the BootP request mode to any of the three following
modes:
•
•
•
BootP or Default IP
BootP Always
BootP or Last Address
BootP or Default IP
The Ethernet Routing Switch 2500 Series operates in the BootP or Default
IP mode (the default mode) as follows:
•
•
After the switch is reset or power cycled, if the switch has a configured
IP address other than 0.0.0.0 or the default IP address, then the switch
uses the configured IP address.
If the configured IP address is 0.0.0.0 or the default IP address
(192.168.1.1/24), then the switch attempts BootP for 1 minute.
•
•
If BootP succeeds, then the switch uses the IP information provided.
If BootP fails and the configured IP address is the default, then the
switch uses the default IP address (192.168.1.1/24).
•
If BootP fails and the configured IP address is 0.0.0.0, then the switch
retains this address.
BootP Always
This option lets you manage the switch that is configured with the IP address
obtained from the BootP server. The Ethernet Routing Switch 2500 Series
operates in the BootP Always mode 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 BootP server is not reachable, you cannot change the in-band
IP address until the BootP mode is set to BootP Disabled. However,
after a period of a few minutes (appoximately 10 minutes), the switch
automatically enters the BootP Disabled mode. You can then configure
the IP address using the CLI.

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 Disabled
This option lets you manage the switch by using the IP address set from the
console terminal. The Ethernet Routing Switch 2500 Series operates in the
BootP Disabled mode as described in the following steps:
•
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 switch IP address
set from the console terminal.
BootP or Last Address
This option lets you manage the switch even if a BootP server is not
reachable. The Ethernet Routing Switch 2500 Series operates in the BootP
or Last Address mode as described in the following steps:
•
When you specify the IP data from the console terminal, the IP address
becomes the in-band address of the switch. BootP requests are not
broadcast. You can manage the switch using this in-band IP address.
•
When you do not specify the in-band IP address 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 the IP address specified as the in-band 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.
Default BootP setting
With Release 4.1 software, the default operational mode for BootP on the
switch is BootP or Default IP. The switch requests an IP address from
BootP only if one is not already set from the console terminal (or if the IP
address is the default IP address: 192.168.1.1).
Flash memory storage
Switch software image storage
The Ethernet Routing Switch 2500 Series uses flash memory to store the
switch software image. The flash memory lets you update the software
image with a newer version without changing the switch hardware (see
switch and the TFTP load host is required to download the software image.

Link Layer Discovery Protocol (IEEE 802.1ab)
Release 4.1 software supports the Link Layer Discovery Protocol (LLDP)
(IEEE 802.1ab), which lets stations connected to a LAN to advertise their
capabilities to each other, enabling the discovery of physical topology
information for network management. LLDP-compatible stations can
consist of any interconnection device including PCs, IP Phones, switches,
and routers. Each LLDP station stores LLDP information in a standard
Management Information Base (MIB), making it possible for the information
to be accessed by a network management system (NMS) or application.
Each LLDP station:
•
advertises connectivity and management information about the local
station to adjacent stations on the same 802 LAN (802.3 Ethernet with
Ethernet Routing Switch 2500)
•
receives network management information from adjacent stations on
the same LAN
ATTENTION
LLDP works in stack mode.
LLDP makes it possible to discover certain configuration inconsistencies or
malfunctions that can result in impaired communications at higher layers.
For example, it can be used to discover duplex mismatches between an IP
Phone and the connected switch.
LLDP is compatible with IETF PROTO MIB (IETF RFC 2922).
Figure 22 "How LLDP works" (page 75) shows an example of how LLDP
works in a network.

Figure 22
How LLDP works
1. The Ethernet Routing Switch and router advertise chassis or port IDs
and system descriptions to each other.
2. The devices store the information about each other in local MIB
databases, accessible using SNMP.
3. A network management system retrieves the data stored by each device
and builds a network topology map.
LLDP operational modes
LLDP is a one-way protocol. An LLDP agent can transmit information
about the capabilities and current status of the system associated with its
MAC service access point (MSAP) identifier. The LLDP agent can also
receive information about the capabilities and current status of the system
associated with a remote MSAP identifier. However, LLDP agents cannot
solicit information from each other.
You can set the local LLDP agent to transmit only, receive only, or to both
transmit and receive LLDP information. You can configure the state for
LLDP reception and transmission using SNMP or CLI commands.
Connectivity and management information
The information fields in each LLDP frame are contained in a Link Layer
Discovery Protocol Data Unit (LLDPDU) as a sequence of short, variable
length, information elements known as type, length, value (TLV). Each
LLDPDU includes the following four mandatory TLVs:
•
chassis ID TLV

76 System configuration software features
•
•
•
port ID TLV
Time to Live TLV
End Of LLDPDU TLV
The chassis ID and the port ID values are concatenated to form a logical
MSAP identifier that is used by the recipient to identify the sending LLDP
agent and port.
A non-zero value in the Time to Live (TTL) field of the TTL TLV indicates
to the receiving LLDP agent how long the LLDPDU information from the
MSAP identifier remains valid. All LLDPDU information is automatically
discarded by the receiving LLDP agent if the sender fails to update it
in a timely manner. A zero value in TTL field of Time To Live TLV tells
the receiving LLDP agent to discard the information associated with the
LLDPDU MSAP identifier.
In addition to the four mandatory TLVs, Release 4.1 software supports the
basic management TLV set. You can specify which of these optional TLVs
to include in the transmitted LLDPDUs for each port.
The optional management TLVs are as follows:
•
•
•
•
Port Description TLV
System Name TLV
System Description TLV
System Capabilities TLV (indicates both the system supported
capabilities and enabled capabilities, such as end station, bridge, or
router)
•
Management Address TLV
Transmitting LLDPDUs When a transmit cycle is initiated, the LLDP
manager extracts the managed objects from the LLDP local system MIB
and formats this information into TLVs. The TLVs are then inserted into
the LLDPDU.
LLDPDUs are regularly transmitted at a user-configurable transmit interval
(tx-delay), or when any of the variables contained in the LLPDU are
modified on the local system (such as system name or management
address). Tx-delay is the minimum delay between successive LLDP frame
transmissions.
TLV system MIBs The LLDP local system MIB stores the information for
constructing the various TLVs to be sent. The LLDP remote system MIB
stores the information received from remote LLDP agents.

Ethernet port management features
Autosensing and autonegotiation
The Ethernet Routing Switch 2500 Series is an autosensing and
autonegotiating device:
•
The term autosense refers to the ability of a port 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. Autonegotiation
lets the switch select the best of speed and duplex modes.
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 standard. In this case, because it is not possible to
sense the duplex mode of the attached device, the Ethernet Routing Switch
2500 Series reverts to half-duplex mode.
When autonegotiation-capable devices are attached to the Ethernet Routing
Switch 2500 Series, the ports negotiate down from 100 Mb/s speed and
full-duplex mode until the attached device acknowledges a supported speed
and duplex mode.
Custom Autonegotiation Advertisements
Custom Autonegotiation Advertisements (CANA) lets you customize
the capabilities that you advertise. For example, if a port is capable of
10/100/1000 full duplex operation, the port can be configured to only
advertise 10 half-duplex capabilities.
CANA lets you control the capabilities that are advertised by the Ethernet
switches as part of the autonegotiation process. In the current software
releases, autonegotiation can either be enabled or disabled.
When autonegotiation is disabled, the hardware is configured for a single
(fixed) speed and duplex value. When autonegotiation is enabled, the
advertisement made by the product is a constant value based upon all
speed and duplex modes supported by the hardware.

78 System configuration software features
When autonegotiating, the switch selects the highest common operating
mode supported between the switch and its link partner.
In certain situations, it is useful to autonegotiate a specific speed and
duplex value. In these situations, the switch can allow for attachment at an
operating mode other than its highest supported value.
For example, if the switch advertises only a 100 Mbps full-duplex capability
on a specific link, the link goes active only if the neighboring device is also
capable of autonegotiating a 100 Mbps full-duplex capability. This prevents
mismatched speed and duplex modes if customers disable autonegotiation
on the neighboring device.
ATTENTION
The CANA feature is available only for built-in 10/100 Ethernet ports and combo
ports (not available for rear ports).
You can only enable CANA through the CLI. When CANA is enabled on a port,
autonegotiation status is displayed as Custom in the web-based management
interface.
High speed flow control
The high speed flow control feature lets you control traffic and avoid
congestion on the gigabit full-duplex link. If the receive port buffer becomes
full, the Ethernet Routing Switch 2500 Series 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.
High speed flow control cannot be configured unless you set Autonegotiation
to Disabled on the port and the speed/duplex is at 1000/full.
Two high speed flow control modes are available:
Symmetric mode
This mode lets both GBIC port and its link partner to send flow control
pause frames to each other.
When a pause frame is received (by either the GBIC 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.

Other features 79
Asymmetric mode
This mode lets the link partner send flow control pause frames to the
GBIC 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 GBIC port is disabled from transmitting pause frames to its
link partner. Use this mode when the GBIC port is connected to a buffered
repeater device.
You can choose a high speed flow control mode using CLI commands. For
more information about the commands see "Enabling flow control" (page
Rate Limiting Configuration
The Rate Limiting feature lets you configure the threshold limits for broadcast
and multicast packets ingressing on a port for a given time interval. The
Ethernet Routing Switch 2500 Series drops any packets received above the
threshold value if the traffic ingressing on the port exceeds the threshold.
The hardware restrictions on this platform do not allow you to determine if
the traffic from a port is the cause of excess broadcast or multicast traffic.
Consequently you cannot perform port specific actions such as disabling
a port. You can generate a trap to detect the excess traffic or you can
configure the switch to store a message in the system log when the traffic
on the port exceeds the threshold value. This message in the system log
conveys that some traffic to the switch is dropped.
When the volume of either packet type is high, placing severe strain on
the network (often referred to as a "storm"), you can set the forwarding
rate of those packet types to not exceed a specified percentage of the total
available bandwidth. The pps (Packets Per Second) value you set is a small
amount of the maximum value of pps for the maximum available bandwidth
that is 262143 pps.
ATTENTION
All Rate Limiting configuration settings are applied across the entire unit. You
cannot set some ports in the unit to limit broadcast traffic with a value of X pps
and some other ports in the same to limit multicast traffic with a value of Y pps.

82 CLI Basics
CLI command modes
Most CLI commands are available only under a certain command mode.
The Ethernet Routing Switch 2500 Series has the following four command
modes:
•
•
•
•
User EXEC
Privileged EXEC
Global Configuration
Interface Configuration
The User EXEC mode is the default mode; it is also referred to as exec.
This command mode is the initial mode of access on powering-up the
Ethernet Routing Switch 2500 Series. In this command mode, the user can
access only a subset of the total CLI commands; however, the commands
in this mode are available while the user is in any of the other four modes.
The commands in this mode are those you would generally need, such
as ping and logout.
Commands in the Privileged EXEC mode are available to all other modes
but the User EXEC mode. The commands in this mode allow you to perform
basic switch-level management tasks, such as downloading the software
image, setting passwords, and booting the Ethernet Routing Switch 2500
Series. The Privileged EXEC mode is also referred to as privExec mode.
The Global Configuration mode and the Interface Configuration mode allow
you to change the configuration of the Ethernet Routing Switch 2500 Series.
Changes made in these command modes are immediately applied to the
switch configuration and saved to NVRAM.
The Global Configuration commands allow you to set and display general
configurations for the switch, such as the IP address, SNMP parameters,
the Telnet access, and VLANs. The Global Configuration mode is also
referred to as config mode.
The Interface Configuration commands allow you to configure parameters
for each port, such as speed and duplex mode. The Interface Configuration
mode is also referred to as config-if mode.

Port numbering 85
•
If you have logged into the CLI with read-write access, you enter the
CLI in privExec mode and use the commands to move to the other
command modes.
Port numbering
The port numbering for different versions of Ethernet switches are listed as
follows:
•
Ethernet Routing Switch 2526 has 24 10/100 Mb/s ports on the front, as
well as two combo ports, which includes two GBIC or two copper ports
at 10/100/1000Mbps. The switch also provides two 1000 Mb/s ports on
the rear panel.
•
Ethernet Routing Switch 2550 has 48 10/100 ports on the front, as well
as two combo ports, which includes two GBIC or two copper ports at
10/100/1000Mbps. The switch also provides two 1000 Mb/s ports on
the rear panel.
The CLI uses the variable <portlist> when a command specifies one or
more ports for the command.
Port numbering in Standalone Mode
In a Standalone Mode, the port number variable is an integer between 1 and
52 for Ethernet Routing Switch 2550 and 1 to 28 for Ethernet Routing Switch
2526. You can use the <portlist> variable in the following formats:
•
A single port number— a integer between 1 and 52.
— Example: 7 means port 7
•
A range of port numbers— a pair of port numbers between 1 and 52
separated by a dash.
— Example: 1-3 means ports 1, 2, and 3
— Example: 5-24 means all ports from port 5 through port 24
•
A list of port numbers and/or port ranges, separated by commas.
— Example: 1,3,7 means ports 1, 3, and 7
— Example: 1-3,9-11 means ports 1, 2, 3, 9, 10, and 11
— Example: 1,3-5,9-11,15 means ports 1, 3, 4, 5, 9, 10, 11, and 15
•
•

General navigation commands
When you enter "?" at any point in the CLI session, the system retrieves
help information for whatever portion of the command you entered thus far.
The system records the last command in a CLI session. However, the last
command is not saved across reboots.
Add the word no to the beginning of most CLI configuration commands to
clear or remove the parameters of the actual command. For example, when
you enter the command ip address 192.32.154.126, you set the IP
address. However, when you enter no ip address, the system returns
alphabetical list of no commands.
Add the word default to the beginning of most CLI configuration
commands to set the parameters of the command to the factory default
default commands.
When you enter a portion of the command and press the [Tab] key, the
system finds the first unambiguous match of a command and displays that
command. For example, if you enter down+[Tab], the system displays
download.

exit
The exit command has no parameters or variables.
reload command
The reload command provides you with a configuration rollback
mechanism to prevent loss of connectivity to a switch, typically for remote
configurations. The reload command lets you temporarily disable the
autosave feature for a specified time period (1 to 60 minutes), allowing you
to make a number of configuration changes on remote switches without
affecting the current saved configuration.
During the interval in which the autosave feature is disabled by the reload
command, you must use the copy config nvram, write memory, or
save config command to force a manual save of your configurations.
Once the reload timer expires, the switch reloads the last saved
configuration. To abort the switch reload before the timer expires, you must
enter the reload cancel command.
The reload command provides you with a safeguard against any
misconfigurations when you perform dynamic configuration changes on
a remote switch.
The following example describes how you can use the reload command
to prevent connectivity loss to a remote switch.
Step Action
1
Enter the CLI command reload force 30. This instructs the
switch to reboot in 30 minutes, loading the configuration from
NVRAM.
During this 30-minute period, autosave of the configuration to
NVRAM is disabled.

5
Execute dynamic switch configuration commands, which take effect
immediately. These configurations are not saved to NVRAM.
If the configurations cause no problems and switch connectivity is
maintained, you can perform the following:
Save the current running configuration using the copy config
nvram, write memory, or save config command.
Since the new configuration is working properly, cancel the reload
using the reload cancel command.

94 CLI Basics
If you make an error when performing configurations in Step 2 that results in
the loss of switch connectivity (for example, an error in the IP address mask,
MLT configuration, or VLAN trunking), the reload command provides you
with a safeguard: when the reload timer expires, the switch reboots to the
last saved configuration, and connectivity is re-established. Therefore, you
do not have to travel to the remote site to reconfigure the switch.
Initiate the reload command before you start the switch configuration
commands. Once you initiate the command in the CLI, the following
message appears:
Reload (y/n) ?
Enter yes at this prompt to set the switch reload.
The following warning message then appears:
Warning the switch has been set to reload in <xx> minutes.
Current configuration has NOT been saved. Configuration must
be explicitly saved.
Once the reload timer expires, the switch resets, reloads the last saved
configuration, and re-enables the autosave feature.

The reload command is executed in the Privileged EXEC command mode.
shutdown command
The shutdown command lets you safely shut down and power off the
switch. Once the shutdown command is initiated, the switch saves the
current configuration and instructs users to power off the switch within the
specified time period (1 to 60 minutes); otherwise, the switch performs a
reset.

subsequent CLI sessions display the following message:
The shutdown process is in progress. It is safe to poweroff
the stack. Configuration changes will not be saved.
Shutdown has blocked the flash. Autoreset in <xxxx> seconds.
ATTENTION
You can disable switch ports that are trunk members, if you choose to disable
them one by one. If you choose to disable all ports of the unit or stack, the
changes cannot have effect on the ports belonging to MLTs.

Getting Started with Device Manager
The Java Device Manager (JDM) software is a Graphical User Interface
(GUI) that lets you manage the switch. JDM (also referred to as Device
Manager) provides options found in other management tools such as
management of VLANs and MultiLink Trunks, and displaying and printing
of statistics in graph format.
To use Device Manager, you must have network connectivity to a
management station running Device Manager on one of the supported
platforms. You must also assign an IP address to the switch.
This chapter contains information on the following topics:
•
•
Installing Device Manager
The JDM software is provided on the device software CD as a self-extracting
executable file, and is also available from the Nortel web site. This chapter
provides instructions for installing the JDM software in a Windows*, UNIX*,
or Linux* environment.
The Java Runtime Environment (JRE) is bundled with the JDM software and
does not require a separate installation.
For details on installing Device Manager, see the following sections:

102 Getting Started with Device Manager
JDM installation precautions
The following warnings apply to Device Manager on all operating
environments:
•
•
•
The JDM and Ethernet Routing Switch software versions must match for
the correct dialog boxes and information to be shown and accessible.
Please see the Release Notes for a complete compatibility list.
If you want to use JDM to support multiple Nortel switches in your
network, ensure that the JDM version you use supports each version of
software running on each Nortel device in your network.
Prior to upgrading JDM, either uninstall your previous version of the
Device Manager software, or install the new software to a different
directory. (You can have multiple versions of Device Manager stored on
your Windows, UNIX, or Linux machine, provided that each version
is stored in a separate directory.)
ATTENTION
Do not install the JDM to a directory where a previous version of Device
Manager software already exists.
•
•
JDM saves the IP addresses that are visited to a settings file. A JDM
uninstall operation does not remove this settings file.
— In a Windows environment, the settings file is dm.xml, and is created
in the jdm folder, under window user profile directory.
— In a UNIX environment, the settings file is ~/.jdm/dm.xml.
— In a Linux environment, the settings file is ~/.jdm/dm.xml.
The dm.xml file containing IP addresses visited from a previous JDM.
Installing the Device Manager software
Device Manager software can be installed in Windows, UNIX, or Linux
environment. The following sections provide information on the system
requirements and installation procedures to install Device Manager software
in Windows, UNIX, and Linux environments.

JDM can exist on one system, as long as each version is in a separate location.
If you decide to allow previous versions of JDM to remain, then you must choose
a different folder to use during the installation process.
Remove existing versions of Device Manager software by using the Uninstall
DM option that was created in the Windows Start menu during installation.
For example, to remove Device Manager from a Windows XP system using
the default program group, choose the following option from the Windows
Start menu: All Programs>Nortel>Java Device Manager>Uninstall DM.

Power over Ethernet for the Ethernet
Routing Switch 2526T-PWR and
2550T-PWR
The Ethernet Routing Switch 2550T-PWR and 2526T-PWR provide IEEE
802.3af-compliant power over half of the front-panel RJ-45 ports, located on
the left-hand side of the front panel. The switch provides power discovery,
power management, and statistics on power use on each port and each
switch basis. You can use the Ethernet Routing Switch 2500 Series to
provide power to network appliances, such as IP telephones, wireless
access points, and video devices.
The Ethernet Routing Switch 2526T-PWR and 2550T-PWR provide Power
over Ethernet for 12 and 24 ports with respectively. The switches only
support PoE on the lower-numbered ports (identified by a red border). The
switches provide a maximum of 168 Watts of power to PoE ports. Adequate
power is available to supply, on average, 7 Watts for each port on the
2550T-PWR, and 14 Watts for each port on the 2526T-PWR. A maximum of
15.4 Watts is available on any port for any given device.
The Ethernet Routing Switch 2550T-PWR and 2526T-PWR supply data
terminal equipment (DTE) power only on signal pins.
By default, power is allocated based on real time measurements. If the total
Ethernet power budget for the switch is exceeded, the switch sheds load
by shutting down power to ports.
You configure the Power over Ethernet (PoE) parameters on the PoE ports
using the Command Line Interface (CLI), the web-based management
system, or Device Manager (JDM).

Classifica-
tion
Classification is a way to tag different terminals on the power over LAN network
according to their power consumption. Devices such as IP telephones, WLAN
access points, and others are classified according to their power requirements.
The meaning of the classification labels is defined in the IEEE 802.3af
specification.
This parameter is valid only while a device is being powered.
Limit (Watt)
Priority
Sets the maximum amount of power supplied to that port.
The range for Ethernet Routing Switch 2500 Series is 3W to 16W. The default
value is 16W.
Priority is used to determine which port(s) are shut down when the total power
of the Ethernet Routing Switch 2500 Series exceeds the power budget for
that switch (or available DTE power). The lower priority ports are shut down
in favor of higher priority ports.
The range is low, high, and critical. The default value is low.
ATTENTION
When two ports have the same priority and one must be shut down, the port
with the higher port number is shut down first.

ASCII Configuration Generator
The primary goal of the ASCII Configuration Generator (ACG) is to provide
the users of the Ethernet Routing Switch 2500 Series with a tool that lets
them easily modify configuration of a particular switch or stack.
ACG generates an ASCII configuration file which reproduces the behavior of
the current binary configuration file. The user can also rely on this function
to maintain backup configurations, as well as use it as a reliable method for
debugging the current configuration of a switch.
ATTENTION
When you are connected to a stack form the console port, ensure that the console
is on the base unit before downloading an ASCII file.
The Ethernet Routing Switch 2500 Series can download an editable ASCII
configuration file from the TFTP server. You can load the ASCII configuration
file automatically at boot time or on demand using console menus or CLI.
Once downloaded, the configuration file automatically configures the switch
according to the Command Line Interface (CLI) commands in the file. The
maximum size for an ASCII configuration file is 100 KBs; larger configuration
files must be split into multiple files.
For more information on loading the ASCII configuration file automatically,
The commands that are associated with ACG are:

disabled, the hardware is configured for a single (fixed) speed and duplex
value. When auto-negotiation is enabled, the advertisement made by
the switch is a constant value based upon all speed and duplex modes
supported by the hardware. When auto-negotiating, the switch selects the
highest common operating mode supported between it and its link partner.

Working with SNTP
The Simple Network Time Protocol (SNTP) feature synchronizes the
Universal Coordinated Time (UTC) to an accuracy within 1 second. This
feature adheres to the IEEE RFC 2030 (MIB is the s5agent). With this
feature, the system can obtain the time from any RFC 2030-compliant
NTP/SNTP server.
The system retries connecting with the NTP server a maximum of 3 times,
with 5 minutes between each retry. If the connection fails after the 3
attempts, the system waits for the next synchronization time (the default is
24 hours) and begins the process again.
Configuring SNTP
The SNTP_Clock dialog box contains the parameters for configuring Simple
Network Time Protocol (SNTP).
To open the SNTP_clock dialog box, use the following procedure:
Step Action

LLDP Globals tab fields
Field
Description
lldpMessageTxInterval
The interval (in seconds) at which LLDP
frames are transmitted on behalf of this
LLDP agent.
lldpMessageTx
HoldMultiplier
The time-to-live value expressed as
a multiple of the object. The actual
time-to-live value used in LLDP frames,
transmitted on behalf of this LLDP agent,
is expressed by the following formula:
TTL = min(65535, (lldpMessageTxInterval
*lldpMessageTxHoldMultiplier))
For example, if the value of
lldpMessageTxInterval is 30, and
the value of lldpMessageTxHoldMultiplier
is 4, the value 120 is encoded in the TTL
field in the LLDP header.
lldpReinitDelay
lldpTxDelay
The lldpReinitDelay indicates the delay
(in seconds) from when the LLDP Port
AdminStatus of a particular port is disabled
until reinitialization begins.
The lldpTxDelay indicates the delay (in
seconds) between successive LLDP
frame transmissions initiated by value or
status changes in the LLDP local systems
MIB. The recommended value for the
lldpTxDelay is set by the following formula:
1 <= lldpTxDelay <= (0.25 *
lldpMessageTxInterval)
lldpNotificationInterval
This object controls the transmission
of LLDP notifications. The agent
must not generate more than one
lldpRemTablesChange notification-event
in the indicated period, where a
notification-event is the "transmission of
a single notification PDU type to a list
of notification destinations." If additional
changes in lldpRemoteSystemsData
object groups occur within the indicated
throttling period, these trap-events must
be suppressed by the agent. An NMS
must periodically check the value of
lldpStatsRemTableLastChangeTime to
detect any missed lldpRemTablesChange
notification-events, for example, due to
throttling or transmission loss. If notification

RemTablesLast
ChangeTime
The value of the sysUpTime object
(defined in IETF RFC 3418) at the
time an entry is created, modified, or
deleted in tables associated with the
lldpRemoteSystemsData objects, and
all LLDP extension objects associated
with remote systems. An NMS can
use this object to reduce polling of the
lldpRemoteSystemsData objects.
RemTablesInserts
The number of times the complete
set of information advertised by a
particular MSAP is inserted into tables
contained in lldpRemoteSystemsData and
lldpExtensions objects. The complete set
of information received from a particular
MSAP is inserted into related tables. If
partial information cannot be inserted
for a reason such as lack of resources,
all of the complete set of information is
removed. This counter is incremented only
once after the complete set of information
is successfully recorded in all related
tables. Any failures occurring during
insertion of the information set, which
result in deletion of previously inserted
information, do not trigger any changes
in lldpStatsRemTablesInserts because
the insert is not completed yet or in
lldpStatsRemTablesDeletes, because the
deletion is only a partial deletion. If the
failure is the result of a lack of resources,
the lldpStatsRemTablesDrops counter is
incremented once.

Field
Description
RemTablesDeletes
The number of times the complete
set of information advertised by a
particular MSAP is deleted from tables
contained in lldpRemoteSystemsData and
lldpExtensions objects. This counter is
incremented only once when the complete
set of information is completely deleted
from all related tables. Partial deletions,
such as a deletion of rows associated
with a particular MSAP, from some tables,
but not from all tables, are not allowed,
and thus, do not change the value of this
counter.
RemTablesDrops
The number of times the complete set
of information advertised by a particular
MSAP can not be entered into tables
contained in lldpRemoteSystemsData
and lldpExtensions objects because of
insufficient resources.
RemTablesAgeouts
The number of times the complete
set of information advertised by a
particular MSAP is deleted from tables
contained in lldpRemoteSystemsData
and lldpExtensions objects because the
information timeliness interval has expired.
This counter is incremented only once
when the complete set of information is
completely invalidated (aged out) from all
related tables. Partial aging, similar to
deletion case, is not allowed, and thus,
does not change the value of this counter.

Field
Description
FramesErrors
The number of invalid LLDP frames
received on the port, while the LLDP agent
is enabled.
FramesTotal
The number of valid LLDP frames received
on the port, while the LLDP agent is
enabled.
TLVsDiscardedTotal
The number of LLDP TLVs discarded for
any reason.
TLVsUnrecognizedTotal
The number of LLDP TLVs received on
a given port that are not recognized by
this LLDP agent on the indicated port.
An unrecognized TLV is referred to as
the TLV whose type value is in the range
of reserved TLV types (000 1001 - 111
1110) in Table 9.1 of IEEE 802.1AB-2004.
An unrecognized TLV can be a basic
management TLV from a later LLDP
version.
AgeoutsTotal
This counter represents the number of
age-outs that occurred on a given port.
An age-out is "the number of times the
complete set of information advertised by
a particular MSAP is deleted from tables
contained in lldpRemoteSystemsData
and lldpExtensions objects because
the information timeliness interval has
expired." This counter is similar to
lldpStatsRemTablesAgeouts, except that
it is on a per-port basis. This enables
NMS to poll tables associated with the
lldpRemoteSystemsData objects and all
LLDP extension objects associated with
remote systems on the indicated port only.
This counter is set to zero during agent
initialization. When the admin status for
a port changes from disabled to rxOnly,
txOnly or txAndRx, the counter associated
with the same port is reset to 0. The agent
also flushes all remote system information
associated with the same port. This
counter is incremented only once when the
complete set of information is invalidated
(aged out) from all related tables on a
particular port. Partial aging is not allowed,
and thus, does not change the value of
this counter.

Requirements for storing and retrieving configuration parameters on a
TFTP server
The following requirements apply when storing and retrieving configuration
parameters on a TFTP server:
•
The Configuration File feature can only be used to copy standalone
switch configuration parameters to other standalone switches.
•
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.
•
•
The configuration file also duplicates any settings that exist for any GBIC
that is installed in the donor switch.
If you use the configuration file to configure another switch that has
the same GBIC model installed, the configuration file settings can also
apply to and override the existing GBIC settings.

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. After the self-test, the remaining port LEDs indicate their operational
status, as described in the following table.

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.
Autonegotiation modes
Port connection problems can occur when a port (or station) is connected
to another port (or station) that is not operating in a compatible mode (for
example, connecting a full-duplex port on one station to a half-duplex port
on another station).
