If the specified group queue-group-name is not defined as an egress queue-group-template, the
policer command will fail. Further, if the specified group does not exist on the port for the SAPs or
subscribers associated with the sap-egress QoS policy, the policer command will fail. While a group
queue-group-name is specified in a sap-egress QoS policy, the groups corresponding egress template
cannot be deleted. While a port egress queue group is associated with a policer instance, the port queue
group cannot be deleted.
If the specified queue group-queue-id is not defined in the egress queue-group-template queue-group-
name, the policer command will fail. While a queue-id within an egress queue group template is
referenced by a sap-egress QoS policy forwarding class policer command, the queue cannot be deleted
from the queue group template.
If an egress policed packet is discarded by the egress port queue group queue, the source policer
discard stats are incremented. This means that the discard counters for the policer represent both the
policer discard events and the destination queue drop tail events associated with the policer.
The no form of this command is used to restore the mapping of the forwarding class to the default
queue. If all forwarding classes have been removed from the default queue, the queue will not exist on
the SAPs or subscribers 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 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 subscribers will be lost.

Quality of Service Guide
• If the policer policer-id command is successfully executed, the default egress queuing is
performed for the forwarding class using the policer-output-queues queue group and the
queue-id within the group based on the forwarding class map from the group template
• If the policer policer-id queue queue-id command is successfully executed, the specified
SAP queue-id within egress QoS policy is used instead of the default policer output queues.
• If the policer policer-id port-redirect-group-queue keyword is successfully executed, the
system will map the forwarding class to the queue within the egress queue group instance
specified at the time the QoS policy is applied to the SAP, using the forwarding class map
from the queue group template.
• If the policer policer-id port-redirect-group queue queue-id command is successfully
executed, the system will map the forwarding class to the configured queue-id within the
egress queue group instance that is specified at the time the QoS policy is applied to the SAP
(ignoring using the forwarding class map from the queue group template).
• If the policer policer-id group queue-group-name instance instance-id command is
successfully executed, the system will map the forwarding class to the queue within the
specified egress queue group instance using the forwarding class map from the group
template.
• If the policer policer-id group queue-group-name instance instance-id queue queue-id
command is successfully executed, the system will map the forwarding class to the specified
queue-id within the specified egress queue group instance (ignoring the forwarding class map
in the group template).
