The main question is, how do I now get cable length values, for example when the cable is unplugged at the client side?
sh cable-diagnostics interface gigabitEthernet 1/0/5 Port Pair Status Length Error Gi1/0/5 Pair-A Open --- 71 (+/- 2m) Pair-B Open --- 73 (+/- 2m) Pair-C Open --- 46 (+/- 2m) Pair-D Open --- 44 (+/- 2m)
The length is now in the error column, and I can no longer retrieve it via SNMP.

Hi @altlc
Thanks for the reply.
One point prone to operation failure is that before walking the node 1.3.6.1.4.1.11863.6.8.1.3.2 (tpPortCableTestCFEntry), you must first perform a set operation on 1.3.6.1.4.1.11863.6.8.1.3.1 (tpPortCableTestFlush). “Flush” refers to refreshing the cable test results of the port, while 1.3.2 is used to read the refreshed results.
Please try executing the set 0 command on 1.3.1 and let us know the result.
After flushing, 1.3.2 uses CF cable test. For ports that are link up, the returned length is “–” instead of the actual length, which aligns with the results of
show cable carefulin standalone mode.If the results from 1.2.1 are not always accurate, it might indicate a cable issue. Extremely short cables often cannot be detected correctly.
Please let us know the cable length, the cable test results, the link status (up/down), the speed, and the port number of the connected switch.

Hi @altlc
Thank you for your response. Sorry for the misunderstanding before.
In this update, we have aligned the SNMP detection results with the “length” field in the CLI’s cable-diagnostics, which prevents obtaining the length in error cases via SNMP.
We highly value your feedback and are currently discussing corresponding optimization solutions. We will update you as soon as a conclusion is reached. Thank you.
