What is virtualUNIT303?

This sets the T303 signaling timer in seconds, controlling how long the system waits for a SETUP_ACKNOWLEDGE response during connection establishment. Engineers configure this based on expected network latency to avoid premature timeouts on slow or congested links. A value of 4 seconds is typical; the system retries if no acknowledgment arrives within this window.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.19.1.15
snmpwalk -v2c -c public <target> ACMIB::virtualUNIT303

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.19.1.15.1
snmpget -v2c -c public <target> ACMIB::virtualUNIT303.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.19.1.15.1 i <value>
