Using the Command Line
Interface (CLI)
Overview
The CLI 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 the same password protection that is used in the web browser
interface and the menu interface.
Accessing the CLI
Like the menu interface, the CLI is accessed through the switch console , and,
in the switch’s factory default state, is the default interface when you start a
console session. 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 web browser interface.
Also, if you are using the menu interface, you can access the CLI by selecting
the Command Line (CLI) option in the Main Menu.

rized access:
1. Operator
2. Manager
3. Global Configuration
4. Context Configuration
Note CLI commands are not case-sensitive.
When you use the CLI to make a configuration change, the swi tch writes the
change to the Running-Config file in volatile memory. This allows you to test
your configuration changes before making them permane nt. To make changes
permanent, you must use the write memory command to save them to the
