1) Depends. For example with a Sup1a on a 6500 QOS and security acl's shared the same TCAM resources.

On supervisors later than that they have their own TCAM resources -

2) Not sure what the relation would be here. Is there something specific you were thinking of ?

Thanks for your reply jon!

I was just wondering if fib table uses tcam structure or not. Fib table has nothing to do with tcam.

Thanks a lot!
