I don't know a good way of identifying the snmp indexes for every
class-map other than walk the mib in an 'intuitive way', so you have to
find out for your self what specific index you have for your class-map.

Remember that if you remove and then reapply a policy-map on an interface,
the router generates other indexes for that policy-map and child
class-maps.
