hcxStuEthLpbkTestLatency
Module: COM21-HCXSTU-MIB
OID (symbolic): COM21-HCXSTU-MIB::hcxStuEthLpbkTestLatency
OID (numeric): 1.3.6.1.4.1.1141.2.51.1.1.26
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This attribute contains the round trip packet latency recorded by the last loopback test. Again 0 if test failed.
What is hcxStuEthLpbkTestLatency?
This read-only Integer32 records the round-trip packet latency measured by the most recent Ethernet loopback test on this ComPort, again reporting 0 if the test failed, per the description. An admin uses this alongside the loopback rate to characterize responsiveness issues distinct from raw throughput problems. For example, a customer complaining about laggy VoIP calls has their loopback test run, and an elevated hcxStuEthLpbkTestLatency confirms a latency issue on their connection rather than a bandwidth shortfall.
Examples
Walk all instances (SNMPv2c):
