NOTE: TDR is an intrusive test. Do not run TDR on a link that is up and passing traffic.To test and display TDR results, use the following commands.1 To test for cable faults on the TenGigabitEthernetEXEC Privilege modetdr-cable-test tengigabitethernet slot/portBetween two ports, do not start the test on both ends of the cable.Enable the interface before starting the test.Enable the port to run the test or the test prints an error message.2 Displays TDR test results.EXEC Privilege modeshow tdr tengigabitethernet slot/portDisplaying Traffic Statistics on HiGigPortsYou can verify the buffer usage and queue counters for high-Gigabit Ethernet (HiGig) ports and link bundles(port channels). The buffer counters supported for front-end ports are extended to HiGig backplane ports.You can display the queue statistics and buffer counters for backplane line-card (leaf) and switch fabricmodule (SFM - spine) NPU port queues on a switch using the show commands described in this section.Transmit, receive, and drop counters are displayed. Buffer counters include the total number of cells currentlyused by all queues on all ports in a port pipe.The f10-bp-stats.mib is used for gathering statistics about backplane HiGig ports. Line-card NPUs value is 0;SFM NPUs range from 0 to 1.In an NPU unit, port numbering of HiGig ports starts from the last front-end I/O port number used.Use the show hardware sfm hg-stats and show hardware linecard hg-stats commands todisplay traffic statistics about the HiGig links on a line-card or SFM NPU.Use the clear hardware sfm hg-stats and clear hardware linecard hg-stats commands toreset HiGig port statistics.Interfaces 527
