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.

to only those ports on the VLAN with clients that want to receive this

When disabled, intelligent multicasting floods layer 2 multicast traffic to all
ports on the VLAN on which the traffic is received.
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.
