Description (partial)

After removing and re-applying a policy-map with hierarchical class-based 
policer on a Vlan sub-interface on an Engine5/SIP-601 linecard, all policer 
counters displayed in <CmdBold>show policy-map interface<noCmdBold> are zero 
despite traffic being sent through the interface, and the policer no longer
drops excess traffic when configured to do so.

This problem could also affect other SIP-601 interfaces/SPA's and other
ingress QoS configurations.

This problem is only seen under the following conditions:
1) There is a hierarchical shaper configured in the outbound direction on the 
main interface (L3/nC/mD ISE QoS model). 
2) Netflow is enabled on the main interface.
