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 http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/fslocal.html#wp1170945 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!
