Service Egress QoS Policy Forwarding Class Commands
•
•
•
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.
Default none
Parameters policer-id — When the forwarding class policer command is executed, a valid policer-id must be specified.
The parameter policer-id references a policer-id that has already been created within the sap-egress
QoS policy.
Values
Default
port-redirect-group-queue — Used to override the forwarding class default egress queue destination to an
egress port queue group. The specific egress queue group instance to use is specified at the time that the
QoS policy is applied to the SAP. Therefore, this parameter os only valid if SAP based redirection is
required.

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).
