no form to disable the feature.

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.
