What is virtualUNIT309?

This sets the T309 timer in seconds for monitoring whether the VUNI itself remains connected and operational on the physical layer. Engineers configure this to detect when the VUNI link goes down and trigger failover or alerting mechanisms. A value of 10 seconds means the system checks link health every 10 seconds.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.19.1.17
snmpwalk -v2c -c public <target> ACMIB::virtualUNIT309

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.19.1.17.1
snmpget -v2c -c public <target> ACMIB::virtualUNIT309.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.19.1.17.1 i <value>
