Cisco Command History Lab - Part 2

Cisco Command History Lab - Part 2 of 2

The command history buffer is a very useful Cisco IOS feature. Most of us have probably used the history buffer without being aware of its existence via the up and down arrows (or cntl-p and cntl-n).  By default, Cisco IOS maintains the last 10 commands that you have issued (a separate list of 10 commands each for exec and configuration mode).  You can change this number in either exec or configuration mode.

We will look at all of the different ways to tweak and use this command as well as briefly visit the mysterious (and possibly dangerous) 'show history all' command.
