hcxStuEthLpbkTestDuration

Module: COM21-HCXSTU-MIB

OID (symbolic): COM21-HCXSTU-MIB::hcxStuEthLpbkTestDuration

OID (numeric): 1.3.6.1.4.1.1141.2.51.1.1.30

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute specifies the duration of the loopback test in seconds. Default is 5 seconds.

What is hcxStuEthLpbkTestDuration?

This read-write INTEGER (5..80) sets how many seconds the Ethernet loopback test runs for, defaulting to 5 seconds per the description. An admin can extend this duration to gather a more statistically reliable rate/latency measurement on a device suspected of intermittent problems. For example, an admin raises hcxStuEthLpbkTestDuration well above the 5-second default when testing a ComPort with reported intermittent slowdowns, to increase the chance the test window captures the problem.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.51.1.1.30
snmpwalk -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuEthLpbkTestDuration

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.51.1.1.30.1
snmpget -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuEthLpbkTestDuration.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1141.2.51.1.1.30.1 i <value>
