Reports the minimum number of active member links required to keep this LAG operationally up, when minimum-link aggregation mode is enabled. This threshold is what actually determines the failure point for the mode enabled by cienaCesExtAggMinimumLinkAggregation, so an admin tuning LAG resilience would raise this value on a LAG carrying critical traffic that shouldn't stay up on too few surviving links. Setting this to 3 on a 4-member LAG means the LAG goes down entirely once fewer than 3 of its member links remain active, rather than continuing to limp along on just one or two.
