Command Usage
◆ MLD filtering enables you to assign a profile to a switch port that specifies
multicast groups that are permitted or denied on the port. An MLD 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, MLD join reports received on the port
are checked against the filter profile. If a requested multicast group is
permitted, the MLD join report is forwarded as normal. If a requested multicast
group is denied, the MLD join report is dropped.
◆ MLD filtering and throttling only applies to dynamically learned multicast
groups, it does not apply to statically configured groups.
◆ The MLD filtering feature operates in the same manner when MVR6 is used to
forward multicast traffic.
