Cisco Catalyst 802.1q Quick Config

I’m not a Ciso guy and don’t do this all the time, so once I got the right commands I decided to write them down!

Basically, we have a VoIP tagged VLAN that needs to run on top of the Default VLAN. Assuming a Catalyst 2960-S 24 port switch, here are the commands:

config terminal
interface range GigabitEthernet 1/0/1 – 28
switchport mode trunk
switchport nonegotiate
copy running-config startup-config

Now the VoIP VLAN (tag 7) will run on all the ports. Actually, all tags will run on all the ports 🙂
