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.

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 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 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 <Tab> 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.
Nomenclature
When referring to an Ethernet port in a CLI command, the following format is used:
•
For an Ethernet port on a standalone device: Ethernet_type port_number
•
For an Ethernet port on a stacked device: unit_number/Ethernet_type port number
De scr ip t io n
Recalls commands in the history buffer, beginning with the most recent com-
mand. Repeats the key sequence to recall successively older commands.
Returns to more recent commands in the history buffer after recalling com-
mands with the up-arrow key. Repeating the key sequence will recall succes-
sively more recent commands.
