Version Description
9.11.0.0 Introduced on the S6000, S6000–ON, Z9100–ON, and S6100–ON.
Usage Information
Following are the prerequisite for applying a CoPP policy:
• Ensure that the protocols are not running. If protocols are running, issues such as, packets arriving out of
order, may occur.
• Ensure that the service-class cpu-queue-buffer command is not configured. The copp-policy
command will not be available if the service-class cpu-queue-buffer command is configured.
• Ensure that the service-policy rate-limit-cpu-queues command is not configured, The copp-
policy command will not be available if the service-policy rate-limit-cpu-queues is
configured.
• You cannot associate a protocol group with more than one queue.
• Ensure that each queue contains a unique protocol list. A protocol cannot be configured in more than one
queue.
