Displaying CoPP Configuration

The CLI provides show commands to display the protocol traffic assigned to each control-plane queue and the current rate-limit applied to each queue. Other show commands display statistical information for trouble shooting CoPP operation.

Viewing Queue Rates

To view the rates for each queue, use the show cpu-queue rate cp command.

Example of Viewing Queue Rates

DellEMC#show cpu-queue rate cp
Service-Queue  Rate (PPS)
-------------- -----------
Q0             1300
Q1             300
Q2             300
Q3             300
Q4             2000
Q5             400
Q6             400
Q7             1100

Example of Viewing Queue Mapping

To view the queue mapping for each configured protocol, use the show ip protocol-queue-mapping command.
