◆
IGMP filtering enables you to assign a profile to a switch port that
specifies multicast 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.
◆
IGMP filtering and throttling only applies to dynamically learned
multicast groups, it does not apply to statically configured groups.
◆
The IGMP filtering feature operates in the same manner when MVR is
used to forward multicast traffic.
