Introduction

OL-32830-01 Command Line Interface Reference Guide 34

Negating the Effect of Commands

For many configuration commands, the prefix keyword no can be entered to

cancel the effect of a command or reset the configuration to the default value. This

Reference Guide provides a description of the negation effect for each CLI

command.

Command Completion

If the command entered is incomplete, invalid or has missing or invalid parameters,

then the appropriate error message is displayed. This assists in entering the

correct command. By pressing Ta b after an incomplete command is entered, the

system will attempt to identify and complete the command. If the characters

already entered are not enough for the system to identify a single matching

command, press ? to display the available commands matching the characters

already entered.

Keyboard Shortcuts

The CLI has a range of keyboard shortcuts to assist in editing the CLI commands.

The following table describes the CLI shortcuts.

Keyboard Key

Down-arrow Returns the most recent commands from the

history buffer after recalling commands with the

up arrow key. Repeating the key sequence will

recall successively more recent commands.
