Introduction to CLI 28-1
Chapter 28
Introducing the Commands
This chapter introduces the commands and gives a summary of commands available.
28.1 Overview
In addition to the web configurator, you can use line commands to configure the switch. Use line commands for
advanced switch diagnosis and troubleshooting. If you have problems with your switch, customer support may
request that you issue some of these commands to assist them in troubleshooting.
28.1.1 Switch Configuration File
When you configure the switch using either the CLI or web configurator, the settings are saved as a series of
commands in a configuration file on the switch. You can perform the following with a configuration file:
Back up switch configuration once the switch is set up to work in your network.
Restore switch configuration.
Use the same configuration file to set all switches (of the same model) in your network to the same settings.
You may also edit a configuration file using a text editor.
Make sure you use valid commands. The switch rejects configuration files with invalid or
incomplete commands.
28.2 Accessing the CLI
You can use a direct console connection or Telnet to access the CLI on the switch.
The switch automatically logs you out of the management interface after five minutes of
inactivity. If this happens to you, simply log back in again.
28.2.1 Access Priority
You can only access the CLI with the administrator account (the default username is admin and password
is 1234 ).
By default, only one concurrent access to the CLI is allowed via either the console port or Telnet. Console
port access has higher priority.
Use the
configure multi-login
command in the configuration mode to allow multiple concurrent
logins. However, no more than five concurrent login sessions are allowed.
