SetCableNVP
Note: This command supports only OCe11100-series adapters and LPe16202 adapters.
This command sets the NVP, required for the TDRTest command, for the cable that
connects to the physical port associated with the WWPN or MAC.
Supported By
Linux, Solaris, VMware ESXi, and Windows
Syntax
SetCableNVP
Parameters
TDRTest
Note: This command only supports OneConnect adapters that use coax copper cables
such as the 10GBaseT adapter ( OCe11102-xT) .
The TDR test attempts to determine if any cable faults are compromising the integrity
of the link. The test requires that the cable be free of disturbances—'down' and quiet. It
is best if the cable is not terminated; however, if it is terminated then the link partner
must not be active during the test.
For each twisted pair cable (labeled A, B, C, or D):

If a fault cannot be detected, the test output displays “OK” and an estimated
cable length (in meters), if possible. If the length cannot be determined, the
estimated length is displayed as “invalid”.

If one of two faults (a short or an open connection) is detected, the test output
displays the fault type (“Shorted” or “Open”) and the distance to the fault (in
meters).
