> class-map PING

> map-class fram PING
> service-policy PING
>
> int s0/0
> fram class PING

> Nope, this doesn't work either. What could be wrong?

> How about if the class-map is applied on a p2p sub?

> Nope, doesn't work.

> 1st, create the acl like this

> access-list 100 perm icmp any any

> Now, change the class-map to look like this:

> class-map PING
> match access-group 100

> And, test again.
