tnUdldStatusInterfaceNeighborLinkDetectionState

Module: TN-UDLD-MIB

OID (symbolic): TN-UDLD-MIB::tnUdldStatusInterfaceNeighborLinkDetectionState

OID (numeric): 1.3.6.1.4.1.868.2.5.124.3.1.5

Node type: OBJECT-TYPE

Type: TNUdldDetectionState

Access: read-only

Description: Neighbor device link detected state.

What is tnUdldStatusInterfaceNeighborLinkDetectionState?

This reports the UDLD-detected link state as seen from the neighboring device's perspective on this link. Admins compare this against the local link state to fully understand whether both sides of the link agree the connection is healthy and bidirectional. If the local link state is healthy but tnUdldStatusInterfaceNeighborLinkDetectionState shows a problem, the admin knows the unidirectional issue is specifically affecting the neighbor's view of the link.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.124.3.1.5
snmpwalk -v2c -c public <target> TN-UDLD-MIB::tnUdldStatusInterfaceNeighborLinkDetectionState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.124.3.1.5.1
snmpget -v2c -c public <target> TN-UDLD-MIB::tnUdldStatusInterfaceNeighborLinkDetectionState.1
