[c-nsp] 802.1q - Max Number of Subinterfaces

[Brian Turnbow]

The atm cards have limits on the number of pvcs , it depends on your card.
The A3 cards do 4096 and the A6 8000.
The number of sub interfaces is global not card based.
You can do 4096 vlans on a box , but are limited to 256 bridge groups.

Hmmm, anyone know what the max sub-interface limit is on an ATM OC3 card 
for a 7200?
