gsEPortDuplexState
Module: GIGAswitchEthernet-MIB
OID (symbolic): GIGAswitchEthernet-MIB::gsEPortDuplexState
OID (numeric): 1.3.6.1.4.1.36.2.18.39.3.6.1.1.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The value of this object indicates whether this port is operating in full- or half-duplex mode.
The value under-negotiation(3) indicates that the port has not selected an operational duplex setting yet.
What is gsEPortDuplexState?
Reports the port's currently operating duplex mode; under-negotiation(3) means it hasn't settled on one yet. Admins check this to confirm a port actually came up full-duplex rather than falling back to half-duplex.
