Using the Command-Line Interface
How to Use the CLI to Configure Features
Searching and Filtering Output of show and more Commands
You can search and filter the output for show and more commands. This is useful when you need to sort through large
amounts of output or if you want to exclude output that you do not need to see. Using these commands is optional.
To use this functionality, enter a show or more command followed by the pipe character (|), one of the keywords begin ,
include , or exclude , and an expression that you want to search for or filter out:
command | { begin | include | exclude } regular-expression
Expressions are case sensitive. For example, if you enter | exclude output , the lines that contain output are not
displayed, but the lines that contain Output appear.
This example shows how to include in the output display only lines where the expression protocol appears:
Switch#
show interfaces | include protocol
Vlan1 is up, line protocol is up
Vlan10 is up, line protocol is down
Accessing the CLI
You can access the CLI through a console connection, through Telnet, or by using the browser.
Accessing the CLI through a Console Connection or through Telnet
To understand the boot process and the options available for assigning IP information, see Performing Switch Setup
Configuration, page 59
If your switch is already configured, you can access the CLI through a local console connection or through a remote Telnet
session, but your switch must first be configured for this type of access. For more information, see
Setting the Telnet
Password for a Terminal Line: Example, page 184 .
You can use one of these methods to establish a connection with the switch:

Connect the switch console port to a management station or dial-up modem. For information about connecting to
the console port, see the
Hardware Installation Guide Hardware Technical Guide .

Use any Telnet TCP/IP or encrypted Secure Shell (SSH) package from a remote management station. The switch
must have network connectivity with the Telnet or SSH client, and the switch must have an enable secret password
configured.
The switch supports up to 16 simultaneous Telnet sessions. Changes made by one Telnet user are reflected in all
other Telnet sessions.
For information about configuring the switch for SSH, see Configuring the SSH Server, page 179 . The switch
supports up to five simultaneous secure SSH sessions.
After you connect through the console port, through a Telnet session or through an SSH session, the user EXEC prompt
appears on the management station.
