What is cucsFabricEthLanPcEpUdldOperState?

This reports the current UDLD operational state for this specific member port. UDLD runs per physical link, so a unidirectional fault on Fi-A/1/2 specifically would not necessarily show up on its sibling members, making this per-member field the one that actually isolates which cable in the bundle has the fiber-polarity or transceiver problem. A value of 'unidirectional' here, while the other members read 'bidirectional', points at this one link as the culprit for any one-way traffic complaints.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.19.15.1.29
snmpwalk -v2c -c public <target> CISCO-UNIFIED-COMPUTING-FABRIC-MIB::cucsFabricEthLanPcEpUdldOperState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.719.1.19.15.1.29.1
