NOTES:
Multicast IP trac is the trac sent to a group of hosts, which are
are identied by Class D IP addresses ranging from 224.0.0.0 to
239.255.255.255.
Internet Group Management Protocol (IGMP) Snooping is a feature
that allows the switch to intelligently forward multicast trac across
the switch. This prevents the switch from broadcasting trac to all
ports, which could potentially aect network performance.
