Example #3: Show Last Time Domain Reflectometry Tests Use the show copper-ports tdr command in Privileged EXEC mode to display the last Time Domain Reflectometry (TDR) tests on specified ports. The following example displays the last TDR tests on all ports. console#show copper-ports tdr Port Result Length [meters] Date 1/g1 OK 1/g2 Short 50 13:32:00 23 July 2004 1/g3 Test has not been preformed 1/g4 Open 128 13:32:08 23 July 2004 1/g5 Fiber - - Fiber Port Cable Test Example #1: Show Optical Transceiver Diagnostics Use the show fiber-ports optical-transceiver command in Privileged EXEC mode to display the optical transceiver diagnostics. NOTE: The show fiber ports command is only applicable to the SFP combo ports and XFP ports (not the ports on the SFP+ plug-in module). The following example displays the optical transceiver diagnostics. console#show fiber-ports optical-transceiver Port Temp Voltage Current Output Input TX LOS Power Power Fault 1/g3 w OK E OK OK OK OK 1/g4 OK OK OK OK OK E OK 1/g1 Copper Temp - Internally measured transceiver temperature Voltage - Internally measured supply voltage Current - Measured TX bias current Output Power - Measured TX output power in milliWatts Input Power - Measured RX received power in milliWatts TX Fault - Transmitter fault LOS - Loss of signal System Configuration 27
