This boolean read-only value indicates whether revertive mode is enabled for this MC-LAG. When true, it tells an admin that after a failure, the higher-priority chassis will automatically reclaim the active LAG role once it recovers, rather than leaving the previously-active lower-priority chassis in charge. For example, if this is true and the primary chassis comes back online after a failure, the MC-LAG will switch traffic back to it once its recovery hold timer expires.
