Viewing Per-Queue CoPP Counters
To view per-queue counters of CoPP rate-limited trac, use the show control-traffic queue {all | queue-id queue-
number} counters command.
The range of queue-number values is from 0 to 20. The twenty-one control–plane queues are divided into groups of seven queues for the
Route Processor, Control Processor, and line-card CPUs as follows:
• Queues 0 to 6 process packets destined to the Control Processor CPU .
• Queues 7 to 13 process packets destined to the Route Processor CPU.
• Queues 14 to 20 process packets destined to the line card CPU.
In the show output, Rx Counters displays the number of bytes of control-plane trac received, on which queue-based rate limiting is
applied. Tx Counters displays the number of bytes transmitted to a control-plane CPU after queue-based rate limiting is applied. Drop
Counters displays the number of bytes of control-plane trac that have been dropped as a result of queue-based rate limiting.

To clear the per-queue counters of rate-limited trac at the aggregated (switch) or individual queue level, use the clear control-
traffic queue {all | queue-id
queue-number} counters command; for example:
Dell#show control-traffic queue queue-id 6 counters
Queue-ID RxBytes TxBytes Drops
-------- -------- ------- -----
Q6 24016 24016 0
