IOS Command Aliases

Just a quick tip, do you ever get tired of typing in long show commands, particularly the show commands you normally land up running when something isn’t working? IOS has a great feature that allows you to create command aliases. What this means is that you can use an alias such as ’si’ instead of a longer command such as ’show ip interface brief’.

To configure IOS command aliases you simple use the ‘alias’ command. Below I created three separate aliases:

* si = show ip int brief

* ri = reload in 2

* sa = show ip vrf CustomerA (As the VRF name is case sensitive, I find that this really helps alot.)

A#conf t
A(config)#alias exec si show ip int brief
A(config)#alias exec ri reload in 2
A(config)#alias exec sa show ip vrf CustomerA

A#si
