Description: Ethernet port duplex trap enable
What is etherPortDuplexTrapEnable?
This controls whether a trap is generated when the Ethernet port's duplex status changes. The source DESCRIPTION here is just a restatement of the object name, so its behavior is inferred from that name and its sibling etherPortSpeedTrapEnable. An admin would set this to enabled(1) so that a shift from full to half duplex, often a sign of an autonegotiation mismatch, triggers an alert.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.3.3.1.27 snmpwalk -v2c -c public <target> PORT-MIB::etherPortDuplexTrapEnable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.3.3.1.27.1 snmpget -v2c -c public <target> PORT-MIB::etherPortDuplexTrapEnable.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.5812.3.3.1.27.1 i <value>
