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 that are currently applied on each control-plane queue, use the show cpu-queue
rate [all | queue-id id | range from-queue to-queue] command.
Dell#show cpu-queue rate all
