UDLD as a protocol provides mechanisms to detect and disable unidirectional links caused for instance by mis-wiring of fiber strands, interface malfunctions, media converters' faults, etc. It operates at Layer 2 in conjunction with IEEE 802.3's existing Layer 1 fault detection mechanisms. This MIB comprises proprietary managed objects as well the objects required for conforming to the protocol." ::= { softentIND1Udld 1} -- -------------------------------------------------------------- alcatelIND1UDLDMIBObjects OBJECT-IDENTITY STATUS current DESCRIPTION "Branch For UDLD Subsystem Managed Objects." ::= { alcatelIND1UDLDMIB 1 } alcatelIND1UDLDMIBConformance OBJECT-IDENTITY STATUS current DESCRIPTION "Branch for UDLD Module MIB Subsystem Conformance Information." ::= { alcatelIND1UDLDMIB 2 } alcatelIND1UDLDMIBGroups OBJECT-IDENTITY STATUS current DESCRIPTION "Branch for UDLD Module MIB Subsystem Units of Conformance." ::= { alcatelIND1UDLDMIBConformance 1 } alcatelIND1UDLDMIBCompliances OBJECT-IDENTITY STATUS current DESCRIPTION "Branch for UDLD Module MIB Subsystem Compliance Statements." ::= { alcatelIND1UDLDMIBConformance 2 } -- -------------------------------------------------------------- -- -------------------------------------------------------------- -- UDLD MIB -- -------------------------------------------------------------- alaUdldGlobalStatus OBJECT-TYPE SYNTAX INTEGER { enable(1), disable(2) } MAX-ACCESS read-write STATUS current DESCRIPTION "This variable is used to enable or diable UDLD on the switch.
