clear cable-diagnostics
tdr
By default, the results of the previous test (if
any) are present and displayed in response to the show cable-diagnostics tdr
command for the specified port.
Privileged EXEC mode
Use this command to clear TDR test registers before every TDR cable diagnostic test. VCT technology enables the diagnosis of a wire or cable conductor by sending a pulsed signal into the conductor and examining the reflection of that pulse. This method of cable analysis is referred to as TDR. By examining the reflection, the ICX device can detect and report cable data such as line speed, cable length, and link pair status. For more information on VCT TDR cable diagnostic testing, refer to the Virtual Cable Testing section of the RUCKUS FastIron Monitoring Configuration Guide.
Use the command in conjunction with the phy cable-diagnostics
tdr command to test the interface.
Show diagnostic test results using the show cable-diagnostics
tdr command.
The following example clears results from the previous VCT TDR test from the third interface on the second slot of the first device in the stack, and verifies that the results have been cleared.
device# clear cable-diagnostics tdr 1/2/3 device# show cable-diagnostics tdr 1/2/3 No TDR data on port 1/2/3
