Hello everybody,
I have come across configuration problem while implementing "Hierarchical
Policy Maps Using Class-Based Shaping". I have configured a class-map
(class-map icmp - to match icmp traffic) and allocated 10% of bandwidth to
it (policy-map icmp). When I apply the service-policy directly to the
interface I see hits aganist the class-map icmp.
The behaviour is as expected till now.
Now, I created a parent policy-map (icmp1) and called the service-policy
icmp under class-map icmp1 and applied a bandwidth restriction of 512 kbps
under this class. Upon applying the service-policy to the interface, I donot
see any matches under class icmp. The counters in the default queue are
incrementing, neither are the matches aganist the ACL. this is a bit
strange.
Am I missing on something here? Can someone help me out.
On the other hand when I call the service-policy icmp under class-default in
policy-map icmp1 I see matches.
I've done the configuration as suggested in the link below:

Would appreciate any help in this front.
