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.
