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