Introduction
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.
