User Guidelines
To see the full multicast address table (including static addresses), use the
show bridge multicast address-table command.
The Include list contains the ports which are in forwarding state for this
group according to the snooping database. In general, the Exclude list
contains the ports that have issued an explicit Exclude for that specific source
in a multicast group. The Reporters That Are Forbidden Statically list
contains the list of ports which have asked to receive a multicast flow but
were defined as forbidden for that multicast group in multicast bridge.
Note: under certain circumstances, the Exclude list may not contain accurate
information.For example, in the case when two Exclude reports were received
on the same port for the same group but for different sources, the port will
not be in the Exclude list but rather in the Include’ list.
