[c-nsp] Configuring a cisco switch trunk port to allow dot1q and, dot1ad frames

[Paul]

If you want to do what you described you need a switch that supports 
vlan mapping
(switchport vlan mapping 1-2 dot1q-tunnel 3)  to filter only those vlans 
you want into the
tunnel vlan.
Or are you suggesting that you want to use the port as a trunk and a 
tunnel at the same time
where some vlans get tunneled and some go direct to the switch vlan FIB? 
(I think this is
possible with selective q-in-q, but as the other poster said I believe 
you need the ES
modules for the 7600)
