cucsSwEthLanBorderUdldRecoveryAction is a CucsFabricRecoveryAction-typed setting defining what recovery action UCS Manager takes after a UDLD failure is detected on the LAN border domain on a Cisco UCS fabric interconnect, the object that groups its northbound Ethernet uplinks toward the customer network (a cucsSwEthLanBorder row). An admin checks this to know whether an affected border uplink will attempt automatic recovery or require manual intervention after being shut down for a suspected unidirectional fault. For example, if a border uplink stayed down after a UDLD event, an admin would check this recovery-action setting to see whether automatic recovery was even configured.
