[cisco-voip] Voice Vlan Configurations

[Nick Kassel]

There seems to be so many different ways to configure switch ports for
voice and data that I am not sure are configurations are correct.

This is the configs we have been using for our branch offices on 3560
switches, we have vlan 1 as our data vlan and vlan 2 as the voice vlan.

 

Port 24 is the trunk port to the router which has the WAN and voice
configurations.

 

Also what configurations should I use on ports that are just for data?
