Egress policers can be optionally mapped to a local queue instead of a queue group queue where required.
The syntax for assigning one such egress policer mapped to local queue is as below:
*A:Dut-A>config>qos>sap-egress$ pwc
-------------------------------------------------------------------------------
Present Working Context :
-------------------------------------------------------------------------------
<root>
configure
qos
sap-egress 3 create
-------------------------------------------------------------------------------
*A:Dut-A>config>qos>sap-egress$ info
----------------------------------------------
queue 1 create
exit
queue 2 create
exit
policer 2 create
exit
fc ef create
policer 2 queue 2
exit
----------------------------------------------
To a local queue, as in "queue 2" in the previous example, both a policer and also a forwarding class can be concurrently mapped as shown below:
*A:Dut-A>config>qos>sap-egress$ info
----------------------------------------------
queue 1 create
exit
queue 2 create
exit
policer 2 create
exit
fc af create
queue 2
exit
fc ef create
policer 2 queue 2
exit
----------------------------------------------
A queue resource is allocated whenever there is either an fc or a policer referencing it. The local queue is freed when there are no references to it. The local queue cannot be deleted when it is being referenced. Exceed-profile traffic from the policer is counted as out-of-profile traffic in the egress local queues.
