Use the Multicast > IGMP Snooping > IGMP Member (Add Static Member)
page to statically assign a multicast service to an interface.
Multicast filtering can be dynamically configured using IGMP Snooping and
IGMP Query messages (see "Configuring IGMP Snooping and Query
Parameters" on page 515 ). However, for certain applications that require
tighter control, it may be necessary to statically configure a multicast
service on the switch. First add all the ports attached to participating hosts
to a common VLAN, and then assign the multicast service to that VLAN
group.

◆ Static multicast addresses are never aged out.
◆ When a multicast address is assigned to an interface in a specific VLAN,
the corresponding traffic can only be forwarded to ports within that
VLAN.
