Chapter 1: Introduction
Purpose
The Avaya Ethernet Routing Switch 4000 Series Troubleshooting guide describes the
diagnostic tools and utilities available with the Avaya Ethernet Routing Switch 4000 Series to
help you troubleshoot operational and configuration issues. This document guides you through
some common problems, to achieve a first tier solution to these situations, and advises you
what information to compile prior to troubleshooting or calling Avaya for help.
You can configure and display files, view and monitor port statistics, trace a route, run loopback
and ping tests, test the switch, and view the address resolution table. Although the diagnostic
tools and utilities described are available with both the Avaya Command Line Interface (ACLI)
and Enterprise Device Manager (EDM), this document focuses on using ACLI to demonstrate
most of the troubleshooting tasks. You can access ACLI through either a direct console
connection to the switch or by using the Telnet or SSH protocols to connect to the switch
remotely.
