Chapter 5: General diagnostic tools

The Ethernet Routing Switch 5600 Series device has diagnostic features available with Enterprise Device
Manager (EDM) and Avaya command line interface (ACLI).
You can use these diagnostic tools to help you troubleshoot operational and configuration issues.
You can configure and display files, view and monitor port statistics, trace a route, run loopback and ping
tests, test the switch fabric, and view the address resolution table.
This document focuses on using ACLI to perform the majority of troubleshooting.
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.

ACLI command modes

This section helps you to understand ACLI command modes and how they differ.
ACLI has five major command modes, listed in order of increasing privileges:
• User Executive mode:
The User Executive mode (also referred to as exec mode) is the default ACLI command
mode. User Executive is the initial mode of access when the switch is first turned on and
provides a limited subset of ACLI commands. This mode is the most restrictive ACLI mode
and has few commands available.
• Global configuration mode:
While using the Privileged EXEC mode (also referred to as Privileged Executive mode)
you can perform basic switch-level management tasks, such as downloading software
images, setting passwords, and booting the switch. With the unrestricted Privileged
Executive is an unrestricted mode you can view all settings on the switch. While you are
logged in with write access you can access all configuration modes and commands that
affect operation of the switch (such as downloading images or rebooting).
• Global configuration mode: While using the Global Configuration mode (also referred to
as config mode) you can set and display general configurations for the switch such as IP
address, SNMP parameters, Telnet access, and VLANs.
• Interface configuration mode:
