Multicast Filter
In certain switch applications, the administrator may want to control the multicast
services that are available to end users. For example, an IPTV service is based on a
specific subscription plan. The multicast filtering feature fulfills this requirement by
restricting access to specified multicast services on a switch port.
Multicast filtering enables you to assign a profile to a switch port that specifies
multicast groups that are permitted or denied on the port. A multicast filter profile
can contain one or more, or a range of multicast addresses, but only one profile can
be assigned to a port. When enabled, multicast join reports received on the port are
checked against the filter profile. If a requested multicast group is permitted, the
multicast join report is forwarded as normal. If a requested multicast group is denied,
the multicast join report is dropped.
