how to change the size of the history command buffer

I spent last week skiing in Polish winter capital – Zakopane. You probably noticed that I didn’t post any new article but weather was wonderful and I had no motivation to turn on my notebook ;).

As plenty of things, after my vacation, keeping me busy, today a short post about command buffer size.

By default the size of the history command buffer is 10. This means that last 10 commands entered by the user can be stored on the memory and repeated using the CLI “↑” key. The range of the command buffer can be tuned and its range is 0 to 256.

How to change the size of the history command buffer?
[labnarioR1]user-interface vty 1
[labnarioR1-ui-vty1] history-command max-size 50

Now, using the CLI “↑” key, we can repeat last 50 commands entered by the user. Command can be used on Console, VTY and TTY user terminal interfaces.
