Can you post the relevant config(s) you had on the 3945 that you're trying to transplant over to the ASR1002, zrob_12
Also, was this configured on the inbuilt GE interfaces on the 3945 chassis, or was this an add-on module that you did this
configuration you speak of?
If you're trying to do as I think you are, I agree with nosx
in that the ASR1xxx GE interfaces are LAYER3
interfaces, not layer 2; you can do subinterfaces on them but they will NOT take any "switchport access vlan ..."
or similar commands on them.
