IGMP Filtering and Throttling
In certain switch applications, the administrator may want to control the
multicast services that are available to end users. For example, an IP/TV
service based on a specific subscription plan. The IGMP filtering feature
fulfills this requirement by restricting access to specified multicast services
on a switch port, and IGMP throttling limits the number of simultaneous
multicast groups a port can join.
IGMP filtering enables you to assign a profile to a switch port that
specifies multcast groups that are permitted or denied on the port. An
IGMP 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,
IGMP join reports received on the port are checked against the filter
profile. If a requested multicast group is permitted, the IGMP join report
is forwarded as normal. If a requested multicast group is denied, the IGMP
join report is dropped.
