The commands saved in the history command buffer are in the same format in which you typed the
commands. If you type an incomplete command, the command saved in the history command
buffer is also an incomplete one.
•
If you execute the same command repeatedly, the switch saves only the earliest record. However, if
you execute the same command in different formats, the system saves them as different commands.
For example, if you execute the
display cu
command repeatedly, the system saves only one
command in the history command buffer. If you execute the command in the format of
display cu
and
display current-configuration
respectively, the system saves them as two commands.

By default, the CLI can save up to 10 commands for each user. To set the capacity of the history
