z
If neither the port type nor the port
number is specified, the statistics
information about the suppression on
all the multicast source ports on the
switch is displayed.
z

suppression on the multicast source
ports of the type is displayed.
z
If both the port type and the port

Three kinds of tables affect data transmission. Their correlations are as follows:
z
Each multicast routing protocol has its own multicast routing table.
z
The multicast routing information of all multicast routing protocols is integrated to
form the core multicast routing table.
z
The core multicast routing table is consistent with the multicast forwarding table,
which is actually in charge of multicast packet forwarding.
