When configuring a router I often use different show commands to check or troubleshoot the configuration. I always hate to type in the whole show command, so I use aliases instead. Aliases are also used in the Open Source community, when working with a terminal.
There are multiple options for the alias command, lets take a closer look:
Cisco IOS includes some built-in command aliases (of course, the Cisco IOS always accepts the shortest unique command). Default command aliases are for example:
p for ping | h for help |
lo for logout | u and un for undebug |
w for where | r for resume |
Next are some alias command, which I use very often:
ALIAS EXEC
Router(config)# alias exec s show ip int brie | exclu unass
Router(config)# alias exec si show int status
Router(config)# alias exec r show run
Router(config)# alias exec rr show ip route
ALIAS CONFIGURE
Router(config)# alias configure vl1 interface vlan1
Router(config)# alias configure eigrp router eigrp 1024
ALIAS INTERFACE
Router(config)# alias interface ns no shutdown
Router(config)# alias interface load load-interval 30
