show control-traffic protocol Display per-protocol counters of rate-limited control-plane traffic. C9000 Series Syntax Parameters show contol-traffic protocol [cp-switch | linecard slot-id portset portpipe | pe pe-id stack-unit unit-number portset port-pipe ] counters cp-switch Enter the keyword cp-switch to display counters for rate-limited traffic on the central switch (aggregated CoPP). linecard slot-id Enter the slot ID and port pipe to display counters for rate-limited traffic on a portset port-pipe 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 Command Modes EXEC Privilege Command 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) 9.2(1.0) Introduced on the C9010. Introduced on the Z9500. Usage Information Example (PE) In the show control-traffic protocol output, RxBytes displays the number of bytes of controlplane 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/ + TxBytes/ = 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.
