MSFC3 performance fallback bridging

Unanswered Question

I consider to implement fallback bridging on

a Catalyst 6500 with WS-SUP720-3B (MSFC3+PFC3B).

This is a solution for non-routable (IBM) traffic that

needs to be forwarded between the 6500 VLANs.

I am concerned that the bridging may affect

the performance of the MSFC3 however.

Should I be concerned at all?

What is a safe number for the aggregate bridged

traffic throughput (for MSFC3)?

Any counter-indications for fallback bridging

MSFC3 in general?

You must configure bridge-groups to do any bridging.Fallback bridging means you are routing IP and bridging the other stuff

(AT, IPX, SNA). Use the vlan-bridge protocol. Eg:

int vlan 10

ip add

bridge-group 1

bridge 1 protocol vlan-bridge
