Active Monitor
This field allows you to determine whether or not the management station will
participate in active monitor contention. The contention process occurs as part of
the recovery procedures initiated after certain ring error situations, and is used to
select a new Active Monitor for the ring. If you disallow contention for the
selected management station, that station will not participate in the contention
process, and will therefore never be chosen as Active Monitor.
