When a subscriber packet is mapped to a child policer through the SAP egress QoS policy, the actual egress queue group is derived from the subscriber host identification process within the subscriber management module; otherwise the default queue-group is used.
When egress policed packets are directed to a local SAP queue, and, when this is configured, the output of a show service id id sap sap-id sap-stats only counts these packets through the policer; they are not counted a second time through the queue to avoid double counting. Consequently, any packets sent directly (not through a policer) to a local SAP post-policer queue are not counted in the sap-stats output. The output of show service id id sap sap-id stats always counts these packets in both the related policer and queue. If it is required to count packets sent directly to the local SAP post-policer queue in the sap-stats output, the packets could be sent into a policer with the rate set to max, then into the local SAP queue.
