8.3.8.0 Introduced on the S4810.
Usage
Information
Create a policy-map by associating a queue number with the qos-policy.
Create QoS policies prior to enabling this command.
When you apply a QoS input policy-map for rate-limiting control-plane traffic (CoPP), you must enter the
keyword cpu-qos.

Version Description
9.2(1.0) Introduced on the Z9500.
8.3.19.0 Introduced on the S4820T.
8.3.11.1 Introduced on the Z9000.
8.3.8.0 Introduced on the S4810.
Usage
Information
This command applies the service-policy based on the type of protocol defined in the ACL rules.
Create ACL and QoS policies prior to enabling this command.
When you apply a QoS input policy-map for rate-limiting control-plane traffic (CoPP), you must enter the
keyword cpu-qos.
If you configure rate-limiting of control protocols on a per-protocol basis and if you modify the rate using
the rate-police command in QOS-POLICY-IN mode while traffic is being passed, packet drops for the
specified protocols may occur if you configure a rate higher than the default rate for a protocol.
