2911 with one serial card and 2 hwic-4esw cards

[robpeay]

I have configured a 2911 with one serial interface card and 2 hwic-4esw cards.  I configured 2 vlans on the router.  the serial card is in slot 0, and the 2 esw's are in slot 1 and 2.  the 4esw in slot 1 works fine.  I can communicate across both vlans with that card.  the second card, has no communication, even though I have the exact same configuration on the ports.

In order to use two cards at the same time, you will need to "stack" them. You will need to connect both cards using a crossover cable. So for 2x hwic-4esw, in total you will only have 6 usable ports because two ports are being used to connect/stack these two cards together.

This can be achieved by using switchport stacking-partner command on the interface level.
