The majority of this document applies to all the above listed Supermicro switch products. In any
particular sub section however, the contents might vary across these switch product models. In those
sections the differences are clearly identified with reference to particular switch product models. If any
particular switch product model is not referenced, the reader can safely assume that the content is
applicable to all the above listed models.
Throughout this document, the common term "switch" refers to any of the above listed
Supermicro switch product models unless a particular switch product model is noted.

1.1 IGMP Snooping Basics

Switches learn the source MAC addresses for unicast traffic and forward the unicast traffic only to the
required ports. But for multicast and broadcast traffic, switches forward the traffic to all ports except for
the port that received that traffic. This basic multicast switching function helps all hosts connected to
the switch to receive the multicast traffic.
In practical deployments, all hosts connected to a switch may not run the same multicast applications.
The hosts that do not run multicast applications receive the multicast traffic unnecessarily. Similarly the
