Using the Revert Command
If the current reference goes offline or becomes unstable the revert command allows the clock to
revert to a higher-priority reference.
When revert is ‘switching enabled’ a valid timing reference of the highest priority is used. If a
reference with a higher priority becomes valid, a reference switch over to that reference is
initiated. If a failure on the current reference occurs, the next highest reference takes over.
If non-revertive switching is enabled, the valid active reference always remains selected even if a
higher priority reference becomes available. If the active reference becomes invalid, a reference
switch over to a valid reference with the highest priority is initiated. The failed reference is
eligible for selection once it becomes operational.
