An entry describes the multicast operational data for the group/source addresses associated to a port. The system creates a row in this table for each port and group/source address configured on the snooping profile associated to that port. The system destroy a row on this table when the related group/source configuration is removed form the profile associated to that port. If a port is associated with a profile not defining any static group/source there will not be any entry for that port on this table.
