xivAbout This Guide
Related Documents
Appendix A, Spanning Tree Concepts, introduces you to the IEEE 802.1D Spanning Tree
Protocol. This protocol is used to resolve the problems of physical loops in a network by
establishing one primary path between any two switches in a network.
Appendix B, System Restart Menu Screen, introduces you to IEEE 802.1Q-compliant virtual
LANs (VLANs). This capability provides a highly efficient architecture for establishing VLANs
within a network and for controlling broadcast/multicast traffic between workgroups.
Appendix C, Class of Service, introduces you to the Class of Service capability, which is based on
the IEEE 802.1p standard specification. This capability allows you to assign mission-critical data
to a higher priority through the switch by delaying less critical traffic during periods of congestion.
Higher priority traffic through the switch is serviced first before lower priority traffic.
Appendix D, IP Multicast Filtering, introduces you to the Internet Group Management Protocol
(IGMP). This protocol runs between hosts and their nearest neighboring multicast router/switch.
The protocol’s mechanisms allow a host to inform its local router that it wants to receive
transmissions addressed to a specific multicast group.

Introduction
This chapter provides an overview of the tasks that may be accomplished using Local Management
(LM), and an introduction to LM screen navigation, in-band and out-of-band network
management, screen elements, and LM keyboard conventions.
Important Notice
Depending on the firmware version used in the switch module, some features described in this
document may not be supported. Refer to the Release Notes shipped with the switch module to
determine which features are supported.
1.1OVERVIEW
The switch module provides a menu-driven system configuration program referred to as Local
Management. This program can be accessed by a direct or modem connection to the COM port on
the switch module (out-of-band), or by a Telnet connection over the network (in-band).
The Local Management is based on SNMP (Simple Network Management Protocol). This SNMP
agent permits a switch to be managed from any PC in the network using in-band management
software.
The switch module also includes an embedded HTTP Web agent. This Web agent can be accessed
using a standard Web browser from any computer attached to the network.
The system configuration program and the SNMP agent support management functions such as:
•Enable/disable any port
•Set the communication mode for any port
•Configure SNMP parameters
•Select RMON options
•Display system information or statistics
•Configure the switch to join a Spanning Tree
Introduction1-1
Overview
•Download system firmware
•Restart the system
There are three ways to access Local Management:
•Locally using a VT type terminal connected to the COM port.
•Remotely using a VT type terminal connected through a modem.
•In-band through a Telnet connection.
1.1.1The Management Agent
The management agent is an entity within the switch module that collects statistical information
(e.g., frames received, errors detected) about the operational performance of the managed network.
Local Management communicates with the management agent for the purpose of viewing statistics
or issuing management commands. Local Management provides a wide range of screens used to
monitor and configure the switch module.
1.1.2In-Band vs. Out-of-Band
Network management systems are often classified as either in-band or out-of-band. In-band
network management passes data along the same medium (cables, frequencies) used by all other
stations on the network. An example of an in-band network management system is the Enterasys
Networks NetSight™.
Out-of-band network management passes data along a medium that is entirely separate from the
common data carrier of the network, for example, a cable connection between a terminal and a
switch module COM port. Enterasys Networks’ Local Management is an out-of-band network
management system.
A module connected out-of-band to the management agent is not connected to the LAN. This type
of connection allows you to communicate with a network module even when that module is unable
to communicate through the network, for example, at the time of installation.
1-2Introduction
Navigating Local Management Screens
1.2NAVIGATING LOCAL MANAGEMENT SCREENS
To navigate within a Local Management screen, use the arrow keys of the terminal or the
workstation providing terminal emulation services. The Local Management screen cursor responds
to the LEFT, RIGHT, UP, and DOWN arrow keys. Each time you press an arrow key, the Local
Management screen cursor moves to the next available field in the direction of the arrow key.
The Local Management screen cursor only moves to fields that can be selected or used for input.
This means that the cursor jumps over display fields and empty lines on the Local Management
screen.
The Local Management screen cursor provides wrap-around operation. This means that a cursor
located at the edge of a screen, when moved in the direction of that edge, “wraps around” to the
outermost selectable item on the opposite side of the screen which is on the same line or column.
1.3LOCAL MANAGEMENT REQUIREMENTS
The switch module provides one communication port, labeled COM, which supports a
management terminal connection. To access Local Management, connect one of the following
systems to the COM port:
•Digital Equipment Corporation VT series terminal.
•VT type terminal running emulation programs for the Digital Equipment Corporation VT series.
•IBM or compatible PC running a VT series emulation software package such as Hyperterm,
which is included in the Windows 9x operating system.
You can also access Local Management using a Telnet connection through one of the network
ports of the switch module.
NOTE: For details on the setup parameters for the console, how to connect a console
to the switch module, or how to make a telnet connection, refer to Chapter 2.
Introduction1-3

program by either a module COM port connection or by a Telnet connection to the module. This
chapter provides the following sections on how to make these connections:
•Management Terminal Setup (Section 2.1), which describes how to make a terminal connection
to the module COM port.
•Telnet Connection (Section 2.2), which provides guidelines on how to make a Telnet connection
to access Local Management.
2.1MANAGEMENT TERMINAL SETUP
The switch module provides one communication port, labeled COM, which supports a
management terminal connection. To access Local Management, connect one of the following
systems to the COM port:
•Digital Equipment Corporation VT series terminal.
•VT type terminal running emulation programs for the Digital Equipment Corporation VT series.
•IBM or compatible PC running a VT series emulation software package such as Hyperterm,
which is included in the Windows 9x operating system.
•You can also access Local Management using a Telnet connection through one of the network
ports of the switch module.
2.1.1Console Cable Connection
Use the Console Cable Kit provided with the switch module to attach the management terminal to
the switch module COM port as shown in Figure 2-1.
Local Management Requirements2-1
Management Terminal Setup
To connect the switch module to a PC or compatible device running the VT terminal emulation,
proceed as follows:
1. Connect the RJ45 connector at one end of the cable (supplied in the kit) to the COM port on the
switch module.
2. Plug the RJ45 connector at the other end of the cable into the RJ45-to-DB9 adapter (supplied in
the kit).
3. Connect the RJ45-to-DB9 adapter to the PC communications port.
NOTE: If using a modem between the VT compatible device and the COM port of the
switch module, use the appropriate connector included in the console cable kit. Refer to
the modem manufacturer’s information for proper operation and setup of the modem.

diagnostics will not run and the module will bootup in less time. If the module fails and you need
to run the diagnostics, change the position of dip switch 5 (on the Mode Switch Bank) on the board
and reboot the module. This changes the startup paramenter to ENABLED and forces the
diagnostics to run when the module is rebooted. For information on the location of the switch and
how to set it, refer to the installation guide shipped with your module.

•Download a new firmware image file from a TFTP server to the switch module,
•Download a configuration file from a TFTP server to the switch module, or
•Upload the configuration file from the switch module to a TFTP server.
Before downloading an image to the device, copy the image to the network TFTP server. A new
firmware image file must be a file from Enterasys Networks; otherwise the agent will not accept it.
The success of the download operation depends on the accessibility of the TFTP server and the
quality of the network connection. After downloading the new image, the agent will automatically
restart itself.
NOTE: For information on how to set up a workstation as a TFTP server, refer to the
specific workstation documentation.
The download and upload configuration capability enables user configured settings to be copied
from one switch module to another via the TFTP server, according to the rules described in this

Using the Spanning Tree Algorithm
7.4USING THE SPANNING TREE ALGORITHM
The Spanning Tree Algorithm (STA) is used to detect and disable network loops, and to provide
backup links between switches, bridges or routers. This allows the switch to interact with other
bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that
only one route exists between any two stations on the network. The Spanning Tree
Configuration:Selection Menu screen (Figure 7-4) provides a menu selection to gain access to the
STA Bridge Configuration and STA Port Configuration screens to configure the STA functions.
To view the current STA bridge and port information, refer to Section 7.5.
For a more detailed description of how to use this algorithm, refer to Appendix A.

changes before it starts to forward frames. In addition,
each port needs time to listen for conflicting
information that would make it return to a blocking
state; otherwise, temporary data loops might result.
The maximum value is 30.
The minimum value is the higher of 4 or
[(Max. Message Age / 2) + 1].

Priority 128 Defines the priority for the use of a port in the STA
algorithm. If the path cost for all ports on a switch are
the same, the port with the highest priority (i.e., lowest
value) will be configured as an active link in the
spanning tree. Where more than one port is assigned
the highest priority, the port with lowest numeric
identifier will be enabled.
The range is 0 - 255.

Parameter Default Description
Cost 100/19/4 This parameter (path cost) is used by the STA to
determine the best path between devices. Therefore,
lower values should be assigned to ports attached to
faster media, and higher values assigned to ports with
slower media.
(Path cost takes precedence over port priority.)
The default and recommended range is:
Ethernet: 100 (50~600)
Fast Ethernet: 19 (10~60)

Status Displays the current state of this port within the spanning
tree:
Disabled – Port has been disabled by the user or has failed
diagnostics.
Blocking – Port receives STA configuration messages, but
does not forward packets.
Listening – Port will leave blocking state due to topology
change, starts transmitting configuration messages, but does
not yet forward packets.
Learning – Has transmitted configuration messages for an
interval set by the Forward Delay parameter without
receiving contradictory information. Port address table is
cleared, and the port begins learning addresses.
Forwarding – The port forwards packets, and continues
learning addresses.
The rules defining port status are:
•A port on a network segment with no other STA
compliant bridging device is always forwarding.
•If two ports of a switch are connected to the same
segment and there is no other STA device attached to this
segment, the port with the smaller ID forwards packets
and the other is blocked.
•All ports are blocked when the switch is booted, then
some of them change state to listening, to learning, and
then to forwarding.
Forward TransitionsNumber of frames forwarded out the port.
Designated Cost The cost for a packet to travel from this port to the root in
the current spanning tree configuration. The slower the
media, the higher the cost.

Designated Port (ID) The priority and number of the port on the designated
bridging device through which this switch must

7.6USING A MIRROR PORT FOR ANALYSIS
You can mirror traffic from any source port to a target port for real-time analysis. You can then
attach a logic analyzer or RMON probe to the target port and study the traffic crossing the source
port in a completely unobtrusive manner. When mirroring port traffic, note that the target port must
be configured in the same VLAN and be operating at the same speed as the source port. (Refer to
Section 7.11 for information on configuring virtual VLANs.) If the target port is operating at a
lower speed, the source port will be forced to drop its operating speed to match that of the target
port.
Use the Mirror Port Configuration screen (Figure 7-10) to designate a single port pair (source and
target ports) for mirroring.

7.7CONFIGURING SMARTTRUNKS
Port trunks can be used to increase the bandwidth of a network connection or to ensure fault
recovery. You can configure up six trunk connections (combining 2 through 8 ports into a fat pipe)
between any two switches. However, before making any physical connections between devices,
use the Trunk Configuration menu to specify the trunk on the devices at both ends. When using a
port trunk, note that:
•The trunk ports must all be front panel ports.
•Ports can only be assigned to one trunk.
•The ports in a trunk must belong to the same switch chip (refer to Tab le 7-1 ).
•The ports at both ends of a connection must be configured as trunk ports.
•The ports at both ends of a trunk must be configured in an identical manner, including speed,
duplex mode, and VLAN assignments.
•The communication mode must be configured identically at both ends of the trunk.
•None of the ports in a trunk can be configured as a mirror source port or mirror target port.
•All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from
a VLAN.
•The Spanning Tree Algorithm will treat all the ports in a trunk as a whole.
•You must enable the trunk prior to connecting any cable between the switches to avoid creating
a loop.
•You must disconnect all trunk port cables or disable the trunk ports before removing a port trunk
to avoid creating a loop.

Table 7-1SmartTrunk, Ports Associated with Group IDs
Multicasting is used to support real-time applications such as video conferences or streaming
audio. A multicast server does not have to establish a separate connection with each client. It
merely broadcasts its service to the network, and any hosts that want to receive the multicast
register with their local multicast switch/router. Although this approach reduces the network
overhead required by a multicast server, the broadcast traffic must be carefully pruned at every
multicast switch/router it passes through to ensure that traffic is only passed to the hosts that
subscribed to this service.
This switch uses IGMP (Internet Group Management Protocol) 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 that received a similar request to that group. It then propagates
the service request on to any neighboring multicast switch/router to ensure that it will continue to
receive the multicast service. (For more information about the use of IGMP snooping and
multicast filtering, refer to Appendix D.)

The default priority for all ingress ports is zero. Therefore, any inbound frames that do not have
priority tags will be placed in the low priority output queue. Default priority is only used to
determine the output queue for the current port; no priority tag is actually added to the frame. You
can use the 802.1P Port Priority Configuration menu screen (Figure 7-15) to adjust the default
priority for any port.

7.11CONFIGURING VIRTUAL LANs
You can use the VLAN configuration menu to assign any port on the switch to any of up to 1024
LAN groups. In conventional networks with routers, broadcast traffic is split up into separate
domains. Switches do not inherently support broadcast domains. This can lead to broadcast storms
in large networks that handle a lot of IPX traffic. By using IEEE 802.1Q compliant VLANs, you
can organize any group of network nodes into separate broadcast domains, confining broadcast
traffic to the originating group. This also provides a more secure and cleaner network environment.
For more information on how to use VLANs, refer to Appendix B. The VLAN configuration
screens are described in the following sections.
