ATM to VLAN local switching on the 7206VXR

We normally interconnect an ethernet VLAN via a bridge-group to an ATM PVC like :

interface ATM1/0.162055

bridge 10

pvc 16/2055

  encap aal5snap


interface port-channel1.10

encapsulation dot1q 10

bridge 10


bridge 10 protocol ieee

This works fine on our 7206VXR's (IOS 12.4(24)) but the limit on bridge-groups is 256 which is not scalable enough.

Earlier i was reading on for L2 switching an ATM PVC to an Ethernet VLAN which interested me because of the simplicity of it. According to the manual, the corresponding config would be :

interface ATM1/0

pvc 16/2055 l2transport

  encapsulation aal5snap



connect atm-eth-vlan-con atm1/0 16/2055 GigabitEthernet0/1.100 interworking ethernet

I've got the following questions :

- Can i terminate the ATM PVC to a port-channel or is it implicit when i configure gi0/1.100?

- Are there any limitations on the amount of connects on the 7200VXR with the IOS i'm using?

- Are there any other caveats i didn't think about?

Thanks a lot!
