You can define a queue-threshold service policy when you want to limit the number of unprocessed packets that a protocol can have at the process level.

A new queue-threshold policy feature is included with CPPr that can be applied to the control plane host subinterface. This feature allows you to limit the number of packets for a given higher-level protocol allowed in the control plane IP input queue. Just as with the port-filter feature, new class map and policy map types have been created for the queue-threshold feature. As with the port-filter feature, the queue-threshold feature supports very specific class map and policy map capabilities.

Follow these three steps to configure a queue-threshold policy:

Step 1 Define a queue-threshold packet classification.

Step 2 Define a queue-threshold service policy.

Step 3 Apply the queue-threshold policy to the host sub interface.
