Description: Total number of loopbacks that were requested by the ACE20 and for which there was no response (not supported).
What is atmSuPortAtmVclStatsTotalFailLoopbacks?
This counter records the number of loopback test requests sent by the ACE20 switch to the far end that did not receive a response within the timeout period, indicating a potential path failure or congestion. Network engineers use failed loopback tests as evidence that the virtual channel is degraded or broken and that either the far end is not responding, the path is congested, or the equipment is malfunctioning. If you initiate 100 loopbacks and 50 fail, the virtual channel is unreliable and should be taken out of service or investigated for configuration errors.
