[c-nsp] Label swapping on 7600 ethernet line cards

[Jose]

It was recently brought to my attention from a colleague that certain 
Ethernet line cards for the 7600 platform do not support label 
swapping.  We currently have WS-X6148-GE-TX line cards and we are 
planning on upgrading them due to their lack of jumbo frame support.  We 
were looking at the WS-X6148A-GE-TX since it has jumbo frame support but 
now the concern is whether this card will be able to swap labels.  Can't 
find any mention of this on CCO.

Our 7600 will be a "P" router and along with the ports on the SUP32, we 
will have PE connections on the 6148A's ports as well.  Hence if two PEs 
need to communicate with each other and they are on the 6148A will this 
fail?  We would never use the 6148A for P to P connections, only for P 
to PE.

Thanks for any tips.
