Module: NETGEAR-UDLD-MIB
OID (symbolic): NETGEAR-UDLD-MIB::agentUdldInterfaceOperStatus
OID (numeric): 1.3.6.1.4.1.4526.10.54.1.2.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This mib object contains the following values, which has the meaning as: 'shutdown' - An Unidirectional link has been detected and the port has been disabled. 'undetermined' - Unidirectional Link Detection protocol has not collected enough information to determine if the link is bidirectional or not. 'biDirectional' - A bidirectional link has been detected. 'notApplicable' - Unidirectional Link Detection Protocol is disabled. 'undetermined-LinkDown' - The port would transition into this state when the port link physically goes down due to any reasons other than the port been put into D-Disable mode by UDLD protocol on the switch.
What is agentUdldInterfaceOperStatus?
This read-only per-interface value reports UDLD's current assessment of the link: shutdown(1) means a unidirectional link was detected and the port disabled, undetermined(2) means not enough data has been gathered yet, biDirectional(3) means the link checks out, notApplicable(4) means UDLD does not apply, and undetermined-LinkDown(5) means the physical link itself is down. Admins poll this to distinguish a UDLD-caused port shutdown from an ordinary link-down event, since both can leave a port unusable. For example, seeing agentUdldInterfaceOperStatus report shutdown(1) on a trunk port tells the admin UDLD disabled it due to a suspected one-way fiber fault, not a cable pull.
