Configuring MAC CPM Filters
CPM filters and queues control all traffic going in to the CPM, including all routing protocols. 
They apply to packets from all network and access ports, but not to packets from a management 
Ethernet port. CPM packet filtering and queuing is performed by network processor hardware 
using no resources on the main CPUs. CPM filters and queues are not configurable on one-slot 
chassis.
The following displays a MAC CPM filter configuration example:

                    exit
                    no shutdown
