ethernetwic on cisco 1921

                   I have a 4 port etherwic daughter card in a 1921 router. I have the hardware port configured as a trunk and have a layer 3 vlan created to handle ip. I have a brand new circuit that works on a laptop and will work on a layer 3 interface(dont have one) but is not working with this setup. I have used a layer 2 switchport to a layer 3 vlan subinterface with IP in the past on 6500's. Any ideas why traffic is not proccessing from layer 2 to layer 3. Any help is appreciated. Carrier said to call cisco.

int gig 0/0/0

desc new carrier_interface

switchport mode trunk

Vlan 125

ip address 10.10.10.1 255.255.255.252
