One of our sites currently runs on a 6509 conhtaining a supervisor WS-X6K-SUP1A-2GE with PFC and MSFC2. I have learned that CEF requires supervisor 2 at least. On the switch CEF is enabled and populated. How is this possible? Is MLS using the CEF fib, or is it really CEF running? Im a bit confused...
in any case the difference is between a flow based traffic based multilayer switching (sup1 msfc1)
and CEF based topology driven multilayer switching (sup2/MSFC2 and above for sure)
You have a sup1A and MSFC2
Cisco Catalyst 6000 series switches with Supervisor Engine I support MLS with a Multilayer Switch Feature Card (MSFC1 or MSFC2) and a Policy Feature Card (PFC). The MSFC2 with PFC2 perform Layer 3 (L3) switching using CEF. The Supervisor Engine 720, PFC3, and MSFC3 perform L3 switching with CEF for the PFC3. Refer to the document Configuring CEF for PFC2 and PFC3 for more information.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
