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 MVR is
used to forward multicast traffic.
