Displaying CoPP Conguration
The CLI provides show commands to display the protocol trac 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.
To view the rates for each queue, use the show cpu-queue rate cp command.
