3.0 Using the Command Line Interface (CLI)
The CLI (Command Line Interface) is a text-based command interface for configuring and
monitoring the switch. The CLI gives you access to the switch’s full set of commands while providing
password protection.
The switch executes a multi-tasking operating system on its control processor that manages all system
activities. This system allows the administrator to query and configure the switch from either an
attached terminal or any of its attached network interfaces.
3.1 Accessing the CLI
This section provides information on how to access the console commands and set or enable the
advanced configuration features in the switch.
The CLI is accessed through the switch console. You can access the console out-of-band by directly
connecting a terminal device to the switch, or in-band by using Telnet either from a terminal device or
through the network interface.
3.2 Using the CLI
The CLI offers the following privilege levels to prevent unauthorized access to the switch:
Operator
Manager
When you use the CLI mode to make a configuration change, the switch writes the changes to the
Running Configuration file in volatile memory. This allows you to test your configuration changes
before making them permanent. To make changes permanent, you must use the save command to
save them to the Startup Configuration file in non-volatile memory. If you reboot the switch without
first using save, all changes made since the last reboot or save (whichever is later) will be lost.
3.3 Privilege Levels at Logon
Privilege levels control the type of access to the CLI. To implement this control, you must set the
Manager password (By default, the manager password is “manager”. If passwords are set when you
use the CLI to log on to the switch, you will be prompted to enter a user then enter a password.
For example:
Example of CLI Login Screen
In the above case, you will enter the CLI at the level corresponding to the user and password
combination you provide (operator or manager). Suppose you log onto the CLI at the Manager level,
the following prompt will appear:
LE2425A#_
OR
LEV2525A#_
