Searching and Filtering Output of show and more Commands Chapter 2 Using the Command-Line Interface 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 GigabitEthernet0/1 is up, line protocol is down GigabitEthernet0/2 is up, line protocol is up 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 Before you can access the CLI, you must connect a terminal or PC to the switch console port and power on the switch, as described in the getting started guide that shipped with your switch. Then, to understand the boot process and the options available for assigning IP information, see Chapter 3, "Assigning the Switch IP Address and Default Gateway." 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 the "Setting a Telnet Password for a Terminal Line" section on page 8-6. 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 switch getting started guide or hardware installation 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. For information about configuring the switch for Telnet access, see the "Setting a Telnet Password for a Terminal Line" section on page 8-6. 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 the "Configuring the Switch for Secure Shell" section on page 8-33. 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. 2-10 Catalyst 2960 Switch Software Configuration Guide OL-8603-04
