Download from Www.Somanuals.com. All Manuals Search And Download.
Console and Telnet Management
Console Management is done through the RS-232 Console Port. Managing the
MIL-S3580 in this method requires a direct connection between a PC and the
MIL-S3580. Telnet management is done over the network. Once the MIL-S3580
has an IP and is on the network, you can use Telnet to log in and change or view
the configuration.
SNMP Network Management
SNMP (Simple Network Management Protocol) provides a means to monitor and
control network devices, and to manage configurations, statistic collection,
performance, and security.
Data is passed from SNMP agents. SNMP agents are hardware & software
processes reporting activity in each network device to the workstation console.
The agent return information is contained in a MIB (Management Information
Base), which is a data structure that defines what is obtainable from the device and
what can be controlled.

Device Control Menu contains 15 submenus where you can add and modify
functions and features of the switch.
3.1. Switch Device Configuration
Figure 3-16. Switch Device Configuration Menu
Use <Space Bar> to toggle the Enable/Disable field and type in the appropriate
value in the Time and Priority fields.
Spanning Tree Enable State is disabled by default on the MIL-S3580. The
switch uses the IEEE802.1D Spanning Tree Protocol (STP), when enabled,
to ensure that only one path at a time is active between any two nodes on the
network.
Dynamic Entry Aging Time - This is the time, in seconds, that the switch
keeps an address of a device in the MAC address table. 300 seconds or 5
minutes is the default. The time can be set from 5 seconds to 999 seconds or
16.65 hours. A MAC address can also be entered in the static address table
to prevent aging out.
Broadcast Storm Prevention can be set to 6%, 20% or Disabled. The
percentage indicates the allowance against the capacity. When disabled,
there is no limitation on the incoming rate of broadcast/multicast traffic,
otherwise limitation on broadcast traffic will be set to the configured
percentage.

Ingress Filtering examines the tagged header of each tagged frame that
enters a port and determines whether the tagged frame and the port that
received the frame are members of the same VLAN. If they belong to the same
VLAN, the port accepts the frame. If they belong to different VLANs, the port
discards the frame. If Ingress filtering is disabled, any tagged frame is
accepted on any port on the switch. It does not matter whether the frame and
port belong to the same or different VLANs.
Per-Port Priority allows port-based priorities. You can designate the priority
for the receiving port so that any frame received will be transmitted to the
destination port with the programmed priority. However, if the received frame
has a layer 3 priority (TOS or DiffServ), it will have precedence over
port-based priority. When set, all ports by default have the lowest priority
possible. If a priority different from lowest is wanted, the priority must be
changed for each individual port in the Port Configuration Menu.
HOLB Prevention - Head Of Line Blocking occurs when many ports send
frames to the same output port. This puts the frames in contention for output
port and all frames must wait behind, thus the head of the line goes first. The
shared memory switching fabric architecture eliminates any possibility of
head-of-line blocking when this feature is enabled.
When QoS is enabled, you can map the Type of Service of your choice
(according to IEEE 802.1p) to the 4 priority levels provided.
There are 3 different modes of VLANs supported in this switch, 802.1Q,
Port-Based VLANs and MTU/MDU. The choice you make here will
ultimately decide the VLAN mode and function for the entire switch. If one
mode is selected, the other two VLAN modes will have no effect on the
switch.
GVRP Enable State is used with IEEE 802.1Q VLANs. GVRP enables the
switch to dynamically create 802.1Q compliant VLAN links with other
switches running GVRP. This reduces the chance for errors in VLAN
configuration by automatically providing VLAN ID (VID) consistency across
the network. You can use GVRP to propagate VLANs to other GVRP
switches instead of manually having to set up VLANs in each switch. In order
to activate GVRP without overlapping VLANs, follow these steps:
1. Assign static VLANs.
2. Take out ports that belong to assigned VLANs from Default VLAN.
3. Assign those ports to Local VID in Switch Port Configuration Menu.
4. Tag the uplink port in the Untagged Configuration Menu.
5. Turn on STP in Switch Configuration Menu.

IGMP Snooping relates to the protocol IGMP. IGMP enables routers to
create lists of devices that are members of multicast groups. A multicast
group might consist of all users that want to see the company yearly meeting
on video. Video is a multicast application. IGMP Snooping enables the
switch to monitor the flow of queries from the devices and the routers. IGMP
Snooping improves the switch's performance by restricting the flow of
multicast packets to only those switch ports, which have devices receiving the
multicast (video).
IGMP Snooping Table Aging Time is the time the switch will maintain its
multicast group(s). The time controls how frequently the switch expects to
see information from devices that want to stay members of multicast groups
and process leaving requests.
3.1. Switch Port Configuration
Figure 3-17. Switch Port Configuration Menu
The ports on this menu are divided and displayed in three separate pages. Twelve
ports are displayed on each of the first two menus, with the two modular uplink
ports displayed on the third page. Use PREV PAGE, NEXT PAGE to list desired
port range. To select a port, highlight that port using <Tab> or arrow keys, and
press <Enter>

3.2. Individual Port Configuration
Figure 3-18. Switch Port Configuration Menu
In Switch Port Configuration Menu, you can configure basic characteristics such as
speed, flow control, and VLAN ID as well as the following features supported by the
switch:
Port Description - Sixteen characters can be entered to identify the port.
Admin State - When set to Disable, the port is inoperable and no devices can
access the switch through the port. The administrator must then enable the
port in order for a link to be established.
Speed and Duplex - There are five different settings that can be set for each
port: Half-duplex-10Mbps, Full-duplex-10Mbps, Half-duplex-100Mbps,
Full-duplex-100Mbps and Auto-negotiation.
Flow Control - When enabled, pause frame is utilized for full duplex
operations and backpressure flow control is utilized for half duplex. By
default, it is enabled.
Per-Port Priority – Four levels of priority (High, Medium, Low and Lowest)
can be set to each individual port. However, the priority level set through QoS
or TOS will have higher precedence.
Bandwidth Management - Eight levels of speed control facilitate the
management of bandwidth. Configuration of receive and transmit control of
each port is independent. You can set the port to transmit and/or receive at

3.5. Spanning Tree Protocol Configuration
Figure 3-23. Spanning Tree Protocol (STP) Configuration Menu
29
Download from Www.Somanuals.com. All Manuals Search And Download.
By default, Spanning Tree is disabled on the MIL-S3580. The switch uses the
IEEE802.1D Spanning Tree Protocol (STP), when enabled, to ensure that only one
path at a time is active between any two nodes on the network. In networks where
there is more than one physical path between any two nodes, STP ensures a single
active path between them by blocking all redundant paths. Having more than one
path between a pair of nodes causes loops in the network, which result in
duplication of messages, leading to "broadcast storms".
As recommended in the IEEE 802.1Q VLAN standard, the MIL-S3580 uses a
single-instance STP, regardless of whether VLANs are configured on the switch.
The Spanning Tree status can be changed with the <Space Bar>. If you enable the
spanning tree protocol, you must complete the Priority and Time fields with
appropriate values. Note that you can choose to leave a menu screen without
applying any changes you had made at any time by pressing <Esc> and then
confirm with <Enter>.
STP Bridge Priority - The range is 0 to 65535. This range specifies the priority
value used along with the switch’s MAC address to determine which device in
the network is root for all the spanning tree switches. The lower a priority value,
the higher the priority. The default is 32768.
STP Bridge Max Age - The range is 6 to 40 seconds. This range specifies the
maximum received message age the switch allows for STP information before
discarding the message. The default is 20 seconds.
STP Bridge Hello Time - The range is 1 to 10 seconds. This is the time
between messages transmitted when the switch is the root. The default is 2
seconds.
STP Bridge Forward Delay - The range is 4 to 30 seconds. This is the time
the switch waits before transitioning from the listening to the learning state and
between the learning state to forwarding state. The default is 15 seconds.

Figure 3-24. Spanning Tree Protocol Port Configuration Menu
In this menu, you can assign spanning priority and path cost to any port. A port with
higher priority and lower path cost is less likely to be blocked if Spanning Tree
Protocol is detecting network loop.
STP Port Priority - Range is 0 to 255. This parameter is used by STP to
determine the port(s) to use for forwarding. The port with the lowest number
has the highest priority. The default is 128.
STP Port Path Cost - The range is 1 to 65,535. This assigns an individual port
cost that the switch uses to determine which ports are the forwarding ports. The
default is 19.
STP Port Topology Change Detection - When enabled, the switch will send a
trap if the Trap Filter menu for the Bridge New Root Trap is also turned-on.
3.7. Port-Based VLAN Configuration
Assigning physical ports within workgroups is simple, and is a common method of
defining a virtual workgroup – VLAN. It delivers the benefit of broadcast control and
simplifies configuration for the network manager. One advantage of the
Port-Based VLAN is its simplicity in configuration.

Figure 3-25. Port Based VLAN Configuration Menu
Port Based VLAN needs to be set in the Switch Device Control Menu before any
configuration in this menu takes effect. By default, the VLAN mode configuration
for the switch is IEEE 802.1Q. Once set to Port Based VLANs, all ports are on the
same VLAN by default. There can be up to 128 different port based VLANs
configured. These VLANs can be overlapping which means that one port can
belong to several different VLANs.
Select the VLAN entry to create, modify, or delete the VLAN group. Use <Space
Bar> to check (join) port(s) to the VLAN group. When a port is joined to a VLAN, it
appears on the menu screen as (X). If the () is blank, the port does not belong to
that VLAN.

3.8. 802.1Q VLAN Configuration
When configuring the IEEE802.1Q VLAN, there are slightly different options available
when the port is configured on the console screen or the web browser. A port on a
VLAN can be in one of three different states.
Normal where the port is not mapped to a specific VLAN but can become a
member through Dynamic VLAN registration. Dynamic VLANs are set when
GVRP learns them. Unless GVRP is running, there is no registration of dynamic
VLANs.
Fixed registration maps a port to a specific or fixed VLAN. The network
administrator can "fix" a VLAN to a specific port with this option. The port can also
be set to another VLAN by dynamic VLAN registration.
Forbidden ports cannot participate in the designated VLAN. They cannot be fixed
members or members of dynamic VLANs. When set to forbidden, the port cannot
communicate with any ports on this VLAN.
33

Once configured there are 3 possible states of the ports that show in the management
menus.
S: shows a static registration of the port and GVRP is not running
D: the port has been registered to the specific VLAN by GVRP
C: the port has been registered to the specific VLAN by GVRP and it was also
set to that VLAN by a network administrator
OTE
NOTE
OTE: A blank indicates that the port is not a member of the VLAN.
On the web browser the ports can be set as Normal, Fixed or Forbidden. The mapping
of the 3 different configuration options on the console versus the web browser are
shown below.

( ) – Port is not set as static (fixed) member of the VLAN but it can become a
member through Dynamic VLAN Registration. Dynamic VLANs occur when GVRP
sets them. Unless GVRP is running, no registration of dynamic VLANs can take
place.
(F) – Port is set as static (fixed) member of the VLAN and can be registered as a
dynamic VLAN member as well.
(B) – Port(s) is being forbidden to participate in the designated VLAN. It cannot be
a static member or a dynamic member of the VLAN. When set, this port cannot
communicate with other ports.
The configuration in Figure 3-27 sets all ports to the default VLAN. They may be
members of a dynamic VLAN as well and to see which dynamic VLANs they
belong to, you must view the Dynamic LAN menu.

3.8.1. Dynamic VLAN Table
Figure 3-28. Dynamic VLAN Table
This screen displays the VLAN mapping for port(s) that join VLAN(s) through
Dynamic VLAN Registration. GVRP enables the switch to dynamically create
802.1Q compliant VLANs on links with other devices running GVRP. This enables
the switch to automatically create VLAN links between other GVRP aware devices.
GVRP reduces the chances for errors in VLAN configuration by automatically
providing VLAN ID consistently across the network.
3.8.2. VLAN Tagged Configuration

All ports are set by default as untagged. To change port(s) to be tagged, use the
<Space Bar> to uncheck - ( ) the port(s). In the above configuration, port 2 will
send out tagged packets. If VLANs need to communicate with other VLANs on the
network, VLAN tagging needs to be set for those ports. Also, in order for GVRP to
work, VLAN tagging of those ports needs to be set.
3.8.3. MTU/MDU Per-Port VLAN Table
Figure 3-30. MTU/MDU Per-Port VLAN Table
This screen allows you to only view the settings made in Switch Device
Configuration menu. It shows that the switch is set to MTU/MDU VLAN mode with
one uplink. If 2 uplinks are configured, ports 1 through 12 map to port 25 and ports
13 through 24 map to port 26.
OTE
NOTE:
OTE When set to MTU/MDU Port VLAN, management over the network
(non-console) can only be done through one of the uplink port. This allows for a
very secure network.

3.9. GARP Configuration
Figure 3-31. GARP Configuration Menu
GARP (Generic Attribute Registration Protocol) defines the architecture, rules of
operation, state machines and variables for the registration and de-registration of
attribute values. It allows dynamic filter entries for VLAN membership to be
distributed among the Forwarding Databases of VLAN-aware switches. By joining
GVRP (GARP VLAN Registration Protocol), it helps maintaining VLAN information.
The rule of the aging scheme is:
GARP Leave All Time > GARP Leave Time > GARP Join Time
OTE
NOTE:
OTE Before GVRP can be enabled, STP must also be enabled, saved, and the
switch must go through a Cold Start in order for configuration to take effect.

Figure 3-32. IGMP Snooping Table
This table shows the multicast groups found by IGMP Snooping. By supporting
IGMP (Internet Group Management Protocol) Snooping, the switch can forward
multicast traffic intelligently. Packets are forwarded to the ports that belong to the
multicast group instead of being broadcasted to all ports and possibly disrupting
network performance. This lookup table reflects up to 32 multicast group(s)
configuration of your system and provides an overview of the port(s) map to each
multicast group.

About Web-based Management
An embedded HTML web server resides in flash memory inside the switch. It
allows users to manage the switch from anywhere on the network through a
standard browser such as Microsoft Internet Explorer or Netscape.
The Web-Based Management is based on Java Applets with an aim to reduce
network bandwidth consumption, enhance access speed and present an easy
viewing screen.
OTE
NOTE:
OTE By default, Internet Explorer 5.0 or later version does not allow Java Applets
to open sockets. The user has to explicitly modify the browser setting to enable

Device Control
Switch Configuration
Figure 4-9. Switch Configuration Menu
Spanning Tree Enable State - By default, Spanning Tree is disabled on the
MIL-S3580. The switch uses the IEEE802.1D Spanning Tree Protocol (STP),
when enabled, to ensure that only one path at a time is active between any two
nodes on the network.
Dynamic Entry Aging Time - This is the time, in seconds, that the switch
keeps an address of a device in the MAC address table. 300 seconds or 5
minutes is the default. The time can be from 5 seconds to 999 seconds or
16.65 hours. A MAC address can also be entered in the static address table
and the MAC address will not age out.
Broadcast Storm Prevention can be set to 6%, 20%, or Disable. The
percentage indicates the allowance against the capacity. When disabled, there
is no limitation on the incoming rate of broadcast/multicast traffic, otherwise
limitation on broadcast traffic will be set to the configured percentage.
Ingress Filtering examines the tagged header of each tagged frame that
enters a port and determines whether the tagged frame and the port that
received the frame are members of the same VLAN. If they belong to the same
VLAN, the port accepts the frame. If they belong to different VLANs, the port
52
Download from Www.Somanuals.com. All Manuals Search And Download.
discards the frame. If Ingress Filtering is disabled, any tagged frame is
accepted on any port on the switch. It does not matter whether the frame and
port belong to the same or different VLANs.
Per-Port Priority allows port based priorities. You can designate the priority
for the receiving port so that any frame received will be transmitted to the
destination port with the programmed priority. However, if the received frame
has a layer 3 priority (TOS or DiffServ) will have precedence over port based
priority. When set, all ports by default have the lowest priority possible. If a
priority different from lowest is wanted, the priority must be changed for each
individual port in the port configuration menu.
HOLB Prevention - Head Of Line Blocking occurs when many ports send
frames to the same output port. This puts the frames in contention for output
port and all frames must wait behind, thus the head of the line goes first. The
shared memory switching fabric architecture eliminates any possibility of
head-of-line blocking when this feature is enabled.
When QoS is enabled, you can map the Type of Service of your choice
(according to IEEE 802.1p) to the four priority levels provided.
There are 3 different modes of VLANs supported in this switch, 802.1Q,
Port-Based VLANs and MTU/MDU. The choice you make here will ultimately
decide the VLAN mode and function for the entire switch. If one mode is
selected, the other two VLAN modes will have no effect on the switch.
GVRP Enable State is used with IEEE 802.1Q VLANs. GVRP enables the
switch to dynamically create 802.1Q compliant VLAN links with other
switches running GVRP. This reduces the chance for errors in VLAN
configuration by automatically providing VLAN ID (VID) consistency across
the network. You can use GVRP to propagate VLANs to other GVRP
switches instead of setting up VLANs in each switch. STP must be enabled
before GVRP is enabled. In order to activate GVRP without overlapping
VLANs, follow these steps:
1. Assign static VLANs.
2. Take out ports that belong to assigned VLANs from Default VLAN.
3. Assign those ports to Local VID in Switch Port Configuration Menu.
4. Tag the uplink port in the Untagged Configuration Menu.
5. Turn on STP in Switch Configuration Menu.
6. Turn on GVRP in Switch Configuration Menu.
7. Update Configuration Setting.
8. Cold Start in System Start Menu.
NOTE: Make sure the port you are connected to is not locked out after

VLANs are assigned.
IGMP Snooping relates to the protocol IGMP. IGMP enables routers to create
lists of devices that are members of multicast groups. A multicast group might
consist of all users that want to see the company yearly meeting on video.
Video is a multicast application. IGMP snooping enables the switch to monitor
the flow of queries from the devices and the routers. IGMP snooping improves
the switches' performance by restricting the flow of multicast packets to only
those switch ports, which have devices receiving the multicast (video).
IGMP Snooping Table Aging Time is the time the switch will maintain its
multicast group(s). It controls how frequently the switch expects to see
information from devices that stay members of multicast groups and process
leaving requests.

Speed and Duplex - There are five different settings that can be set for each
port: Half-duplex-10Mbps, Full-duplex-10Mbps, Half-duplex-100Mbps,
Full-duplex-100Mbps and Auto-negotiation.
Flow Control - When enabled, pause frame is utilized for full duplex
operations and backpressure flow control is utilized for half duplex. By default,
this is enabled.
Per-Port Priority – Four levels of priority (High, Medium, Low and Lowest) can
be set to each individual port. However, the priority level set through
QoS/Type of Service configuration in the Device Configuration Menu will have
higher precedence.

Spanning Tree Protocol Configuration
Spanning Tree is a link management protocol that provides path redundancy while
preventing undesirable loops in the network. For Layer 2 Ethernet network to
function properly, only one active path must exist between two stations.
The Spanning-Tree Algorithm calculates the best loop-free path throughout a
switched network. STP forces redundant data paths into a standby (blocked) state.
If a network segment in the spanning tree fails and a redundant path exists, the
Spanning-Tree Algorithm recalculates the Spanning Tree topology and activates
the standby path.

STP Port Priority - Range is 0 to 255. This parameter is used by STP to
determine the port(s) to use for forwarding. The port with the lowest number
has the highest priority. The default is 128.
STP Port Path Cost - The range is 1 to 65,535. This assigns an individual port
cost that the switch uses to determine which ports are the forwarding ports. The
default is 19.
STP Port Topology Change Detection - When enabled, the switch will send a
trap if the Trap Filter menu for the Bridge is also turned-on.

(D) – Port(s) is set as static (fixed) member of the VLAN and can be registered as a
dynamic VLAN member as well.
(C) – Port(s) is being both a static member and a dynamic member of the VLAN.
Port Based VLAN needs to be set in the Switch Device Control Menu before
configuring this menu will take effect. By default, the VLAN mode configuration for
the switch is IEEE 802.1Q. Once set to Port Based VLANs, all ports are on the
same VLAN by default. There can be up to 128 different port based VLANs
configured. These VLANs can be overlapping which means that one port can
belong to several different VLANs.
Static VLAN Configuration
When configuring the IEEE802.1Q VLAN, there are slightly different options
available when the port is configured on the console screen or the web browser. A
port on a VLAN can be in one of three different states.

Normal where the port is not mapped to a specific VLAN but can become a
member through Dynamic VLAN registration. Dynamic VLANs are set when
GVRP sets them. Unless GVRP is running, there is no registration of dynamic
VLANs.
Fixed registration maps a port to a specific or fixed VLAN. The network
administrator can "fix" a VLAN to a specific port with this option. The port can also
be set to another VLAN by dynamic VLAN registration.
Forbidden ports cannot participate in the designated VLAN. They cannot be fixed
members or members of dynamic VLANs. When set to forbidden, the port cannot
communicate with any ports on this VLAN.
Once configured there are 3 possible states of the ports that show in the

GARP (Generic Attribute Registration Protocol) defines the architecture, rules of
operation, state machines and variables for the registration and de-registration of
attribute values. It allows dynamic filter entries for VLAN membership to be
distributed among the Forwarding Databases of VLAN-aware switches. By joining
GVRP (GARP VLAN Registration Protocol), it helps maintaining VLAN information.
The rule of the aging scheme is:
GARP Leave All Time > GARP Leave Time > GARP Join Time

IGMP Configuration
Figure 4-27. IGMP Configuration Menu
Multicasting is used to support real-time applications such as video conferencing or
streaming audio. IGMP (Internet Group Multicast Protocol) allows you to query for
any attached hosts who want to receive a specific multicast service. The switch
looks up the IP Multicast Group used for this service and adds any port, which
received a similar request to that group. It then propagates the service request on
to any neighboring multicast switch to ensure that it will continue to receive the
multicast service.
By supporting IGMP (Internet Group Management Protocol) Snooping, the switch
can forward multicast traffic intelligently. Packets are forwarded to the ports that
belong to the multicast group instead of being broadcasted to all ports and possibly

5. Network Configuration
This section provides you a few samples of network topology in which the
MIL-S3580 is used.
The Switch provides versatile configuration options for the network. It is ideally
suited as a workgroup or segment Switch in a network; it has the flexibility to
provide switched 10Mbps to the desktop or shared hubs, aggregate traffic from
workgroup switches, or provide dedicated 100Mbps or 1000Mbps (Gigabit) to
servers with bandwidth-intensive applications. And because all Fast Ethernet ports
auto-negotiate for operation at 100 Mbps, the switch is perfectly suited for an
evolving network environment where demand for network speed is increasing.
Collapsed Backbone Application
For small network where rapid growth can be expected in the near future, this
switch is an ideal solution supporting backbone connectivity.
The switch can be used as a standalone switch for a group of heavy traffic users.
Switching is brought to the desktop either through a single end-station per switch
port or through a multi-port switch.
A 1000Mbps server is connected to the switch, providing end stations high-speed
accessibility to its applications. This configuration provides dedicated 100Mbps
connections to the network center, to the server, and up to 40 users (while 2
optional 8-port modules are installed).
When the network needs expansion, you can simply connect the switch to any
IEEE 802.3 (Ethernet), IEEE 802.3u (Fast Ethernet) and 802.3ab (Gigabit Ethernet)
compliant switch utilizing the Auto MDI/MDIX function. This switch can also
cooperate with a wide range of networking devices (e.g., firewall routers and printer
servers) added to the network.

Figure 5-1. Collapsed Backbone Application
Departmental Bridge
For enterprise networks where large data broadcasts are constantly processed,
this switch is an ideal solution for department users to connect to the corporate
backbone. The MIL-S3580 used as a segment switch can alleviate user contention
for bandwidth and eliminate server and network bottlenecks. All ports can connect
to high-speed department servers that need high bandwidth. This switch provides
parallel communications within its Gigabit port, which can run up to 2000Mbps at
Full-duplex.
The switch makes key servers available to more users by allowing multiple
conversations to occur concurrently, thereby significantly expanding overall
network throughput. Moreover, this switch eases supervision and maintenance by
allowing network manager to centralize multiple servers in a single location.
73

Full-duplex operation only applies to point-to-point access (for example,
Figure 5-2: Departmental Bridge Application
NOTE:
when attaching the switch to a workstation, server, or another switch). When
connecting to hubs, use a standard cascaded connection set for half-duplex
operation.
High Performance Switched Workgroup
This switch is also a good solution for connecting two workgroups, supporting the
throughput, for example, of 800Mbps. This application is useful for power groups
that need high bandwidth.
The most common LAN implementations use a combination of standard switches,
bridges and routers. The bridges and routers quickly become bottlenecks,
reducing overall network throughput. Switching to higher-speed LANs such as
FDDI or ATM is not a good choice for most people.
However, such broadband equipment is still extremely expensive and hard to
maintain. Besides, you have to replace all existing Ethernet cables and adapter
cards, restructure your network, and implement more expensive administration
procedures.
74

The switch can provide the same bandwidth of FDDI and ATM at much lower costs.
In addition, all current adapters and network devices can still be used. The
switching cross-domain connection is better than bridge and router because users
can retain LAN structure in which any node can freely communicate with any other
node.
Figure 5-3: High Performance Switched Workgroup Application
IEEE 802.1Q VLAN Application
The switch supports up to 4096 Group ID, IEEE 802.1Q-compatible virtual LAN
(VLANs).
Port-based VLAN Workgroup12s
You can group the switch ports into broadcast domains by assigning them to the
same VLAN to increase network capacity and performance. With network
segmentation, each switch port connects to a segment that is a single broadcast
domain. Packets received in one VLAN can only be forwarded within that VLAN.
VLAN allows the grouping of end stations logically, based not on physical location
but on business policies such as job function or department. Members of a group
can be dispersed throughout a facility - they do not have to be connected in close
physical locations.
75

Hence, group members can coordinate their data communication requirements
regardless of the actual working locations; and the logical network can extend to
any point you want it to. Moreover, VLAN groups can be modified at any time to
add, move or change users without any re-cabling.
Figure 5-4: VLAN Workgroup Application
Shared Server
The MIL-S3580’s compliance to the IEEE802.1Q tagging VLAN standard allows
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 the following figure.
Figure 5-5: Shared Server

In this example, stations on different VLANs share resources. As a result, VLAN 1
and VLAN 2 can access VLAN 3 for printing. The broadcasts from ports configured
in VLAN3 can be seen by all VLAN port members of VLAN3.
