Service SAP QoS Policy Command Reference
Unknown forwarding type packets are mapped to either an ingress multipoint queue (using the
unknown queue-id or unknown queue-id group ingress-queue-group commands) or an ingress
policer (unknown-policer policer-id). The unknown and unknown-policer commands within the
forwarding class context are mutually exclusive. By default, the unknown forwarding type is mapped
to the SAP ingress default multipoint queue. If the unknown-policer policer-id command is executed,
any previous policer mapping or queue mapping for the unknown 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.
The unknown-policer command is ignored for instances of the policer applied to SAPs or subscribers
multiservice site where unknown packets are not supported.
When the unknown forwarding type within a forwarding class is mapped to a policer, the unknown
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 unknown forwarding type within
the forwarding class to the default multipoint queue. If all forwarding class forwarding types had been
removed from the default multipoint queue, the queue will not exist on the SAPs or subscriber or multi-
service site associated with the QoS policy and the no broadcast-policer command will cause the
system to attempt to create the default multipoint queue on each object. If the system cannot create the
queue on each instance, the no unknown-policer command will fail and the unknown forwarding type
within the forwarding class will continue its mapping to the existing policer-id. If the no unknown-
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.
