I have a lab setup where I have a 3845 router with a 4-port POE HWIC. I have a problem getting a phone to trunk to its pc port. I've tried a 7911 and 7961 IP phone. I assigh a voice vlan and an access vlan to the same port and it doesn't work at all. I read some documentation saying I had to configure the port as a trunk so I tried that and the voice vlan worked but the data vlan didnt pass through to the pc port. I hooked up a 2960 to the router and used the same commands and got the data and voice vlans working. Is this a bug with the EtherSwitch models? Does anyone know of a workaround?
