| Multicast Filtering
Layer 2 IGMP (Snooping and Query)
– 480 –
ASSIGNING
INTERFACES TO
MULTICAST SERVICES
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 474). 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.

COMMAND USAGE

the corresponding traffic can only be forwarded to ports within that
VLAN.
