Description: Cisco UCS fabric:EthLanEp:udldOperState managed object property
What is cucsFabricEthLanEpUdldOperState?
This reports the current operational state of UDLD, Unidirectional Link Detection, on this LAN uplink port. UDLD exists specifically to catch a fiber link that is receiving but not transmitting, a fault a simple link-up/link-down check would miss, so this field is what an admin checks when a LAN uplink shows as up but traffic is not actually flowing both ways. A value of 'bidirectional' for Fi-A/1/3 confirms UDLD sees healthy two-way communication with the upstream switch; 'unidirectional' would explain a link that looks up but silently drops traffic.
