www.dell.com | support.dell.com Terminal Command Buffer Every time a command is entered in the CLI, it is recorded on an internally managed Command History buffer. Commands stored in the buffer are maintained on a First In First Out (FIFO) basis.These commands can be recalled, reviewed, modified, and reissued. This buffer is not preserved across device resets. Keyword Source or destination Up-arrow key Ctrl+P Recalls commands in the history buffer, beginning with the most recent command. Repeats the key sequence to recall successively older commands. Down-arrow key Returns to more recent commands in the history buffer after recalling commands with the up-arrow key. Repeating the key sequence will recall successively more recent commands. By default, the history buffer system is enabled, but it can be disabled at any time. For information about the command syntax to enable or disable the history buffer, see history. There is a standard default number of commands that are stored in the buffer. The standard number of 10 commands can be increased to 256. By configuring 0, the effect is the same as disabling the history buffer system. For information about the command syntax for configuring the command history buffer, see history size. To display the history buffer, see show history. 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 guide describes the negation effect for all applicable commands. 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 the button, an incomplete command is entered. 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. Incorrect or incomplete commands are automatically re-entered next to the cursor. If a parameter must be added, the parameter can be added to the basic command already displayed next to the cursor. The following example indicates that the command interface ethernet requires a missing parameter. (config)#interface ethernet %missing mandatory parameter (config)#interface ethernet 62 Using the CLI
