When this object is written with a non-zero value, re-synchronization procedures will be initiated, if necessary, in order to constrain the master and slaves to use the indicated protocol version. When written with zero (0), the master and slaves should use the version dictated by the usual protocol version selection procedures; resynchronization procedures will be invoked, if necessary, to achieve this result.
