Introduction

How to use this guide; related guides; software conventions;getting help; ATXSwitch firmware version
information

Welcome to the NetSight Element Manager for the ATX User’s Guide. We have
designed this guide to serve as a simple reference for using NetSight Element
Manager for the ATX Switch.

The ATX Switch comprises a five-slot chassis along with a high-capacity Packet
Processing Engine (PPE), which occupies an additional top slot. The ATX Switch
is a multiprotocol LAN switch that enables high-bandwidth switching between
Ethernet, Token Ring, FDDI and 100Base-T LANs, with full connectivity to ATM.

The PPE uses a dual RISC processor design combined with specialized switching
hardware to provide wire-speed performance, the intelligence to manage the
bandwidth gained through switching, and the ability to perform core switching
functions (e.g., bridging, routing, programmable filtering, and statistics
gathering).

Up to five modules in any combination can be installed in the ATX Switch chassis,
including Ethernet, Token Ring, FDDI, Fast Ethernet, and ATM modules. The
individual modules, each with at least one RISC CPU of its own, handle interface
control and translation functions at the port level.

The ATX, with its 1.6 Gbps internal bandwidth, combined with each LAN
module’s 400 Mbps bandwidth, offers a total system bandwidth exceeding 3.6
Gbps.

Introduction

Using the ATX Switch User’s Guide

Each chapter in this guide describes one major functionality or a collection of
several smaller functionalities of the ATXSwitch. This guide contains information
about software functions which are accessed directly from the device icon; for
information about functions which are accessed via the NetSight Element
Manager platform, consult the User’s Guide and Tools Guide both of which are
included in this package.

Chapter 1, Introduction, provides a list of related documentation, describes
certain software conventions, and shows you how to contact the Enterasys Global
Call Center.

Chapter 2, The ATX Switch Chassis View, describes the visual display of the ATX
Switch and explains how to use the mouse within the Chassis View;the operation
of enabling and disabling ports is also described here.

Chapter 3, Using ATX Trunking, describes the trunking table and how to enable
and disable trunking on each interface on your ATX.

Chapter 4, Using ATX Port Filtering, describes how to use the Port Filtering
window to create custom filters and discard or forward traffic based on the
specified criteria.

Chapter 5, Workgroup Configuration, describes how to set up virtual work
groups on your ATX.

Chapter 6, ATX Port Mirroring, provides instructions for setting up port
mirroring on your ATX; you can configure a diagnostic port as either a local port
or a remote port on another ATX in your network.

Chapter 7, IPX Routing Tables, describes the IPX Tables window,which contains
statistics about IPX Routing on your ATX.

Chapter 8, ATX Bridging, provides a comprehensive look at all management
options associated with the bridge portion of the ATX, including Spanning Tree,

1. Click on Port Status on the menu bar at the top of the Chassis View window;
a menu will appear.

2. Drag down (and to the right, if necessary) to select the status information you
want to display. The port text boxes will display the appropriate status
information.

Port status view options are:

Status

You can view three port status categories, as follows:

• Bridge — FWD, DIS, LRN, LIS, BLK, BRK, or UNK

• Admin — ON or OFF

• Operator — ON or OFF

If you have selected the Bridge status mode, a port is considered:

• FWD (Forwarding) if the port is on-line and forwarding packets across the
ATX Switch from one network segment to another.

• DIS (Disabled) if bridging at the port has been disabled by management; no
traffic can be received or forwarded on this port, including configuration
information for the bridged topology.

• LRN (Learning) if the Forwarding database is being created, or the Spanning
Tree Algorithm is being executed because of a network topology change. The
port is monitoring network traffic, and learning network addresses.

• LIS(Listening) if the port is not adding information to the filtering database. It
is monitoring Bridge Protocol Data Unit (BPDU) traffic while preparing to
move to the forwarding state.

• BLK (Blocking) if the port is on-line, but filtering traffic from going across the
ATX Switch from one network segment to another. Bridge topology
information will be forwarded by the port.

• BRK (Broken) if the physical interface has malfunctioned.

• UNK (Unknown) if the interface’s status cannot be determined.

If you have selected the Admin status mode, a port is considered:

• ON if the port is enabled by management and has a valid link.

• OFF if it has not been enabled or if it has been disabled through management
action.

If you have selected the Operator status mode, a port is considered:

The ATX Switch Chassis View

• ON if the port is currently forwarding packets.

• OFF if the port is not currently forwarding packets.

Load

If you choose Load, the interface text boxes will display the percentage of
network load processed by each port during the last polling interval. This
percentage reflects the network load generated per polling interval by devices
connected to the port compared to the theoretical maximum load (10 or 100
Mbits/sec) of an Ethernet network.

Errors

If you choose the Errors mode, the interface boxes will display the percentage of
the total number of valid packets processed by each port during the last polling
interval that were error packets. This percentage reflects the number of errors
generated during the last polling interval by devices connected to that port
compared to the total number of valid packets processed by the port.

In NetSight Element Manager, the polling interval is set via the Tools—>Option
window available from the primary window menu bar.

Refer to the NetSight Element Manager User’s Guide for full information on setting
device polling intervals.

I/F Mapping

If you choose the I/F Mapping mode, the interface boxes will display the interface
number (IfIndex) associated with each port in the ATX Chassis.

I/F Speed

If you choose the I/F Speed mode, the port text boxes will display the speed (10 or
100 Mbits/sec) of the network segment connected to each port. The speed of the
network management port will be displayed in Kbits/sec.

I/F Type

If you choose the I/F Type mode, the interface boxes will display the interface
type of each port in the ATX Chassis (e.g., Eth, PPP, FDDI, or TR).

Port Status Color Codes

The Port Status display options —Bridge, Admin, and Operator— incorporate
color coding schemes. For the Admin and Operator Status display options,
green = ON, red = OFF, and blue = N/A (not available). For the Bridge Status
display option, green = forwarding, blue = disabled, magenta = learning and
listening, orange = blocking, red = broken, and gray = unknown.

For all other Port Status selections — Load, Errors, I/F Mapping, I/F Speed, and
I/F Type— color codes will continue to reflect the most recently selected mode
which incorporates its own color coding scheme.

The ATX Switch Chassis View

The Chassis Manager Window

Like most networking devices, Enterasys and Cabletron ATX Switch management
modules draw their functionality from a collection of proprietary MIBs and IETF
RFCs. In addition, many Enterasys and Cabletron intelligent devices – like the
ATX Switch – organize their MIB data into a series of “components.” A MIB
component is a logical grouping of MIB data, and each group controls a defined
set of objects. For example, ATX Switch bridging information is organized into its
own component. Note, too, that there is no one-to-one correspondence between
MIBs and MIB components; a single MIB component might contain objects from
several different proprietary MIBs and RFCs.

The Chassis Manager window, Figure 2-4, is a read-only window that displays
the MIBs and the MIB components — and, therefore, the functionality —
supported by the currently monitored ATX Switch management module.

To view the Chassis Manager window:

1. Click on Help on the far right of the menu bar at the top of the chassis
manager window.

2. Drag down to MIBs Supported, and release.

MIB Components are listed here;
remember, there’s no one-to-one
correspondence between MIBs
and MIB Components

The MIBs which provide the
ATX Switch’s functionality —
bothproprietaryMIBs and IETF
RFCs — are listed here
