Command Mode

Command Usage
• 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.
Example
