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