show control-traffic protocol
Display per-protocol counters of rate-limited control-plane traffic.
C9000 Series
Syntax
show contol—traffic protocol [cp—switch | linecard slot-id portset port-
pipe | pe pe-id stack-unit unit-number portset port-pipe ] counters
Parameters
cp-switch Enter the keyword cp-switch to display counters for rate-limited traffic on the
central switch (aggregated CoPP).
linecard slot-id
portset port-pipe
Enter the slot ID and port pipe to display counters for rate-limited traffic on a
specified line card and port set. The slot ID range is from 0 to 11. The port-pipe ID
value is 0.
pe pe-id Enter the keyword pe and the port extender ID. Range is from 0 to 255.
stack-unit unit
number
Enter the keyword stack-unit and the stack unit number. Range is from 0 to 7.
portset port-pipe Enter the keyword portset and the port-pipe ID. Port pipe ID value is 0.
counters Enter the keyword counters to display the traffic counters.
Defaults None

History
This guide is platform-specific. For command information about other platforms, see the relevant Dell
Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.9(0.0) Introduced on the C9010.
9.2(1.0) Introduced on the Z9500.
Usage
Information
In the show control-traffic protocol output, RxBytes displays the number of bytes of control-
plane traffic received on which protocol-based rate limiting is applied. TxBytes displays the number of
bytes transmitted to a control-plane CPU after protocol-based rate limiting is applied. Drops display the
number of bytes of control-plane traffic that have been dropped as a result of protocol-based rate
limiting.
The number of RxBytes is calculated as: Drops/<packet-size> + TxBytes/<packet-size + 4 bytes> =
RxBytes (total packets received)
To clear the per-protocol counters of rate-limited control-plane traffic at the aggregated (switch) or line
card and port set level, use the clear control-traffic protocol command.
