Usage
Information
In the show output, Rx Bytes displays the number of bytes of control-plane traffic 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 traffic that have been dropped as a result of queue-based rate limiting.
To clear the per-queue counters of rate-limited control-plane traffic at the aggregated (switch) or line
card and port set level, use the clear control-traffic queue command.
Example
Dell#show control-traffic queue queue-id 0 counters

show cpu-queue rate
Display the rates for each control-plane queue.
Z9500
Syntax
show cpu-queue rate [all | queue-id queue-number | range from_queue
to_queue]
Parameters
all Display the rate for all control-plane queues (CPU queues 0–23).
queue-id queue-
number
Display the rate for a specified control-plane queue. The range of CPU queue
values is from 0 to 23.
range
from_queue
to_queue
Display the rate for a range of control-plane queues. The range of CPU queue
values is from 0 to 23. Separate the from_queue value from the to_queue value
with a space; for example, show cpu-queue rate range 8 15.
Defaults Not configured.
Command Modes EXEC Privilege
