duplexStatus
Module: CMM3-MIB
OID (symbolic): CMM3-MIB::duplexStatus
OID (numeric): 1.3.6.1.4.1.161.19.3.4.4.1.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Half-duplex data transmission or Full-duplex data transmission.
What is duplexStatus?
This read-only enumeration reports whether a port is currently operating in fullDuplex(1) or halfDuplex(0) mode. It matters because a port stuck in half-duplex when the attached device expects full duplex is a common cause of the collision counters elsewhere in this MIB climbing. An admin seeing rising txLateCollision on a port would check duplexStatus first to rule out a duplex mismatch as the cause.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.161.19.3.4.4.1.1.4 snmpwalk -v2c -c public <target> CMM3-MIB::duplexStatus
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.161.19.3.4.4.1.1.4.1 snmpget -v2c -c public <target> CMM3-MIB::duplexStatus.1
