Intelligent multicasting refers to the forwarding of multicast traffic
(packets with a multicast destination MAC address) within a VLAN
to a subset of ports participating in that VLAN. It limits the
forwarding of multicast traffic to only those ports on the VLAN with
clients that want to receive this multicast traffic.
When disabled, intelligent multicasting floods layer 2 multicast
traffic to all ports on the VLAN on which the traffic is received.
All traffic that is sent to a particular multicast MAC address is said to
be in a multicast session. The switch supports 58 sessions per VLAN.
Each multicast session keeps track of which ports must receive that
session's multicast traffic within the VLAN. There are two types of
ports: client ports and router ports.
