40.2.5 Maximum Number of Learning Multicast
Configuration Port
You can use the following command to set up each port can learn the number of multicast.
Table 40-5 Maximum number of learning multicast configuration port
Enter global

NUM_MULTICAST_GROUPS
Caution:
NUM_MULTICAST_GROUPS refers to the machine can learn the maximum number of
multicast, each product NUM_MULTICAST_GROUPS may be different. Although
theoretically a maximum of learning multicast port number NUM_MULTICAST_GROUPS, but
also that other ports can learn the number of multicast will be occupied. In other words, all the
ports will share this NUM_MULTICAST_GROUPS multicast group resources.
40.2.6 Configuring MLD Snooping Multicast
Learning Strategies
Configured multicast learning strategies, the administrator can control the router only to
learn the specific multicast group. If a multicast group is added to the blacklist, then the router
will not learn the multicast group; the contrary, in the white list in the multicast group of routers
can be learned.
