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):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.51.1.1.26
snmpwalk -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuEthLpbkTestLatency

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.51.1.1.26.1
snmpget -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuEthLpbkTestLatency.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hcxStuEthLpbkTestLatency.1
