Cisco IOS aliases are a small but useful way to speed up repetitive troubleshooting commands in the CLI. This older note keeps the original examples and adds a little structure so it is easier to reuse in a lab or production runbook.
Why use Cisco IOS aliases?
Aliases are shortcuts for commands you type often. They are especially handy during troubleshooting, when you want quick access to interface status, routing tables, CPU checks, BGP summaries, OSPF neighbors, EIGRP neighbors, or access lists without typing the full command every time.
Example aliases from the original note
To make your life better cisco invented aliases. It's small thing but very handy and speed up your work a little bit.alias exec s show ip int brief
alias exec r show run
alias exec cpu show processes cpu | e 0.00% 0.00% 0.00%
alias exec sir show ip route
alias exec sion sh ip ospf nei
alias exec sien sh ip eigrp nei
alias exec sibs sh ip bgp summ
alias exec sib sh ip bgp
alias exec sal sh ip access-list
Operational notes
- Keep aliases obvious: short names are useful, but they should still make sense during an outage.
- Store common aliases in your lab template or configuration standard so engineers see the same shortcuts everywhere.
- Test aliases after pasting them, especially commands with pipes or filters.
