Description Within a sap-ingress QoS policy forwarding class context, the policer command is used to map packets
that match the forwarding class and are considered unicast in nature to the specified policer-id. The
specified policer-id must already exist within the sap-ingress QoS policy. While the system is
determining the forwarding class of a packet, it is also looking up its forwarding destination. If ingress
forwarding logic has resolved a unicast destination (the packet does not need to be sent to multiple
destinations), it is considered to be a unicast packet and will be mapped to either an ingress queue
(using the queue queue-id or queue queue-id group ingress-queue-group commands) or an ingress
policer (policer policer-id). The queue and policer commands within the forwarding class context are
mutually exclusive. By default, the unicast forwarding type is mapped to the SAP ingress default queue
(queue 1). If the policer policer-id command is executed, any previous policer mapping or queue
mapping for the unicast forwarding type within the forwarding class is overridden if the policer
mapping is successful.
A policer defined within the sap-ingress policy is not actually created on an ingress SAP or a
subscriber using an sla-profile where the policy is applied until at least one forwarding type (unicast,
broadcast, unknown or multicast) from one of the forwarding classes is mapped to the policer. If
insufficient policer resources exist to create the policer for a SAP or subscriber or multi-service site or
ingress policing is not supported on the port associated with the SAP or subscriber or multi-service site,
the initial forwarding class forwarding type mapping will fail.
When the unicast forwarding type within a forwarding class is mapped to a policer, the unicast packets
classified to the sub-classes within the forwarding class are also mapped to the policer.
The no form of this command is used to restore the mapping of the unicast forwarding type within the
forwarding class to the default queue. If all forwarding class forwarding types had been removed from
the default queue, the queue will not exist on the SAPs or subscriber or multi-service sites associated
with the QoS policy and the no policer command will cause the system to attempt to create the default
queue on each object. If the system cannot create the default queue in each instance, the no policer
command will fail and the unicast forwarding type within the forwarding class will continue its
mapping to the existing policer-id. If the no policer command results in a policer without any current
mappings, the policer will be removed from the SAPs and subscribers associated with the QoS policy.
All statistics associated with the policer on each SAP and subscriber will be lost.
