COMMAND USAGE
â—† 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.
â—† IGMP filtering and throttling only applies to dynamically learned
multicast groups, it does not apply to statically configured groups.
â—† The IGMP filtering feature operates in the same manner when MVR is
used to forward multicast traffic.
