ILTERING
This chapter describes how to configure the following multicast services:
– Configures snooping and query parameters.
– Filters specified multicast service, or throttling
the maximum of multicast groups allowed on an interface.
Multicast VLAN Registration (MVR)
– Configures a single network-wide
multicast VLAN shared by hosts residing in other standard or private
VLAN groups, preserving security and data isolation.

VERVIEW
Multicasting is used to support real-time applications such as video
conferencing or streaming audio. A multicast server does not have to
establish a separate connection with each client. It merely broadcasts its
service to the network, and any hosts that want to receive the multicast
register with their local multicast switch/router. Although this approach
reduces the network overhead required by a multicast server, the
broadcast traffic must be carefully pruned at every multicast switch/router
it passes through to ensure that traffic is only passed on to the hosts which
subscribed to this service.
Figure 312: Multicast Filtering Concept
This switch can use Internet Group Management Protocol (IGMP) to filter
multicast traffic. IGMP Snooping can be used to passively monitor or
“snoop” on exchanges between attached hosts and an IGMP-enabled
