Commands are stored in the buffer, which operates on a First In First Out (FIFO) basis. These commands can be recalled, reviewed, modified, and reissued. This buffer is not preserved after switch resets. Keyword Up-arrow key + Down-arrow key + Source or Destination Recalls commands in the history buffer, beginning with the most recent command. Repeats the key sequence to recall successively older commands. Returns to more recent commands in the history buffer after recalling commands with the up-arrow key. Repeating the key sequence recalls more recent commands in succession. By default, the history buffer system is enabled, but it can be disabled at any time. The standard number of 10 stored commands can be increased to 216. 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 the history-size command in the Line command mode chapter of this guide. Negating Commands For many commands, the prefix keyword no is entered to cancel the effect of a command or reset the configuration to the default value. All configuration commands have this capability. This guide describes the negation effect for all commands to which it applies. Show Command The show command executes in the User Executive (EXEC) and Privileged Executive (EXEC) modes. 108
