Chapter 1 CLI Overview Using CLI Variables Send documentation comments to [email protected] Setting the Switch's Terminal Width To set the terminal screen width for the current session, use the terminal width command in EXEC mode. This command is specific to only the console port. Telnet and SSH sessions set the width automatically. The syntax for this command is terminal width columns switch# terminal width 86 Sets the screen length for the current session to 86 columns for the current terminal session. The default is 80 columns. Displaying Terminal Settings The show terminal command displays the terminal settings for the current session: switch# show terminal TTY: Type: "vt100" Length: 24 lines, Width: 80 columns Session Timeout: 525600 minutes Using CLI Variables The SAN-OS CLI parser supports definition and use of variables in CLI commands. CLI variables can be used as follows: • Entered directly on the command line. • Passed to the child script initiated using the run-script command. The variables defined in the parent shell are available for use in the child run-script command process. • Passed as command line arguments to the run-script command. CLI variables have the following characteristics: • You cannot reference a variables through another variable using nested references. • You can define persistent variables that are available across switch reloads. • You can reference only one predefined system variable, the TIMESTAMP variable. User-Defined CLI Session Variables You can define CLI variables the persist only for the duration of your CLI session using the cli var name command in EXEC mode. These CLI variables are useful for scripts that you execute periodically. The following example shows how to create a user-defined CLI session variable. switch# cli var name testinterface fc 1/1 You can reference a variable using the syntax $(variable). The following example shows how to reference a user-defined CLI session variable. switch# show interface $(testinterface) fc1/1 is up Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN) OL-16217-01, Cisco MDS SAN-OS Release 3.x Cisco MDS 9000 Family Command Reference 1-27
