IP Phone with URT

I have an Ip Phone connected to a switch and my Pc is connected to the IP Phone.

I have configured the port on the Switch with a Voice Vlan for the telephony, and the ip phone function Properly. In the case of the Pc i want to configure to take the vlan asignment dinanically through an URT, but this doesn't function.

Can i really configure the Voice Vlan Statically on the switch and the data Vlan Dynamically on the same port of the Switch???

if i try to configure Both Vlans statically, the Voice and the data Vlans function correctly.


Re: IP Phone with URT

The cat4, 5 and 6k support dynamic vlan membership and static voice auxiliary vlans simultaneously.

Because VMPS on a dot1q trunk is supported. While the cat3500XL, 2900XL, etc.. do not. So in the

latter cats you can only have a dynamic port config with the 1 vlan or a static port config with native VLAN and Aux VLAN.
