Passive or active direct attach SFP/SFP+ cables are not based onBaseT technology and do not support TDR testing.The maximum distance the Virtual Cable Tester (VCT) can function is 120 meters.ExamplesThe following example results in a report on the cable attached to port 1/0/3.console#test copper-port tdr te1/0/1
