ctEtherDuplexAdminStatus
Module: CTRON-ETHERNET-PARAMETERS-MIB
OID (symbolic): CTRON-ETHERNET-PARAMETERS-MIB::ctEtherDuplexAdminStatus
OID (numeric): 1.3.6.1.4.1.52.4.1.2.4.2.3.1.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The administrative status requested by management for the duplex of this port. The value of halfduplex(2) indicates that if Auto-Negotiation is disabled for this port, that the port will operate in half duplex, provided that the port supports half duplex, as specified by ctEtherSupportedDuplex.
The value of fullduplex(3) indicates that if Auto-Negotiation is disabled for this port, that the port will operate in full duplex, provided that the port supports full duplex, as specified by ctEtherSupportedDuplex.
In all cases, if the value specified does not indicate a duplex that the port supports the set will fail.
What is ctEtherDuplexAdminStatus?
This is the manually configured duplex setting that takes effect on this port only when Auto-Negotiation is disabled. It lets an admin force a specific duplex mode for links where negotiation can't be relied upon. For example, setting fullduplex(3) on a point-to-point fiber link known to support it avoids the collision overhead of half duplex once auto-negotiation is turned off.
