Module: CISCOSB-UDLD-MIB
OID (symbolic): CISCOSB-UDLD-MIB::rlUdldBidirectionalState
OID (numeric): 1.3.6.1.4.1.9.6.1.101.218.1.1.5
Node type: OBJECT-TYPE
Type: UdldPortBidirectionalState
Access: read-only
Description: This variable identifies the port UDLD status (shutdown, idle, detection, undetermined, bidirectional).
What is rlUdldBidirectionalState?
This read-only UdldPortBidirectionalState value reports a port's current UDLD link-verification status, such as shutdown, idle, detection, undetermined, or bidirectional. An admin cares because 'bidirectional' confirms the link partner has been verified to see traffic back correctly, while other states signal an unverified or failed link that could be a hidden one-way fiber fault. For example, a port stuck reporting 'undetermined' instead of 'bidirectional' would prompt an admin to physically inspect the fiber pair for a swapped or damaged strand.
