Cisco IOS Commands

Commands frequently used in Cisco IOS, so I don't forget them.

Informational Commands

Bring up a disabled interface

no shut

Show all registered VLANs (and associated access ports)

show vlan brief

Show allowed VLANs on a particular trunk port

sh int Gi0/43 trunk

Return all IPs registered to the switch

show ip interface brief

If the ports are only VLAN carriers, exclude unneeded stuff:

show ip interface brief | exclude unassigned

Show port security info

sh port-security address

Show port security info for a specific switchport

sh port-security int Gi0/2

Show existing config files / flash memory

show flash

Device info (IOS version, etc)

show version

Most IOS commands can be abbreviated like int for interface or brie for brief.. what I use in my notes is dependent on how lazy I was at the time I saved the command.
