Usage Guidelines The TDR test is supported on Catalyst 4500 series switches running Cisco IOS Release 12.2(25)SG for
the following line cards only:
• WS-X4548-GB-RJ45
• WS-X4548-GB-RJ45V
• WS-X4524-GB-RJ45V
• WS-X4013+TS
• WS-C4948
• WS-C4948-10GE
The valid values for interface interface are fastethernet and gigabitethernet.
Do not start the test at the same time on both ends of the cable. Starting the test at both ends of the cable
at the same time can lead to false test results.
Do not change the port configuration during any cable diagnostics test. This action may result in
incorrect test results.
The interface must be operating before starting the TDR test. If the port is down, the results of the test
will be invalid. Issue the no shutdown command on the port.
