etherPortAutonegAdvDuplex
Module: PORT-MIB
OID (symbolic): PORT-MIB::etherPortAutonegAdvDuplex
OID (numeric): 1.3.6.1.4.1.5812.3.3.1.31
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This specifies what duplex capability is advertised for autonegotiation. If Full Duplex is set, then Half Duplex is also adveetised.This does not apply to Gig Ethernet Phys, since they do not autonegotiate speed or duplex.
What is etherPortAutonegAdvDuplex?
This sets which duplex mode (half or full) the port advertises during autonegotiation. Advertising full duplex automatically also advertises half duplex as a fallback option, and like the speed equivalent, this doesn't apply to Gigabit Ethernet PHYs that don't autonegotiate duplex. An admin would use this to prevent a port from ever settling into half duplex by restricting the advertised set to full only.
