swIfDuplexAdminMode
Module: CISCOSB-rlInterfaces
OID (symbolic): CISCOSB-rlInterfaces::swIfDuplexAdminMode
OID (numeric): 1.3.6.1.4.1.9.6.1.101.43.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This variable specifies whether this interface should operate in half duplex or full duplex mode. This specification will take effect only if swIfSpeedDuplexAutoNegotiation is disabled. A value of 'none' is returned if a value of the variable hasn't been set.
What is swIfDuplexAdminMode?
This read-write enumerated INTEGER (none/half/full) sets the administratively configured duplex mode for an interface, taking effect only when auto-negotiation is disabled, per the description. Admins configure this to force a link into full or half duplex when connecting to equipment that doesn't negotiate properly, avoiding the classic duplex-mismatch problem that causes high collision rates. For example, forcing full duplex here when connecting to an old device that mis-negotiates would prevent the excessive late collisions typical of a duplex mismatch.
