Question : Cisco 2950 Vlan for Voice

I have a new network i am setting up. I have a cisco 2950 switch. I also have several cisco 7940 phones. I have a Microsoft Small Business Server 2003, and a Druid Phone System.

I need instructions on how to setup the switch to seperate the data and voice lans. Please give me detailed step by step instructions. I have wiped the switch clean and can telent into it. I need the phones to be setup on vlan 512 and the data to stay on vlan1. Thanks

Answer : Cisco 2950 Vlan for Voice

It would be something like this

description IPphone+PC
switchport trunk encapsulation dot1q
switchport mode trunk
switchport access vlan 2
switchport voice vlan 100
switchport trunk allowed vlan 2,100
spanning-tree portfast


The purpose of the trunk command is to allow the port to use multiple VLAN's.  The old 2900 series switches need this setting, newer switches aren't like this.
