the vlan mapping configuration will exist on all ports in the port group -- much like port-based qos bits on a per linecard basis.

<pseudocode>
int gi 1/1
  vlan 1 map 11
  vlan 2 map 12

int gi 1/2
  vlan 1 map 11
  vlan 2 map 12
</pseudocode>

if you activate vlan mapping on an interface, it inherits all maps on the port group.
in my experience (for what its worth) -- this is really to be used as a one-off, temporary fix type of solution.  its not permanent -- especially as each linecard on c6k has a varied experience (i.e. number of port groups and translations per port group).
