This table contains entries to control multicast groups for alarm collection. This table allows for multiple groups of alarms to be collected. It is expected that a higher level manager will add entries to this table and the transponders multicast address table. When trap contention modes are used polling will be disable while an active entry in this table has contention enabled. This way the polling does not interfere with the possible asynchronous notifications. As default this table shall have one entry, containing the broadcast address. This is a non-volatile table.
