4.3.6.3 MLD Snooping Port Group Filtering
In certain switch applications, the administrator may want to control the multicast services that are available to end users. For
example, an IP/TV service based on a specific subscription plan. The MLD filtering feature fulfills this requirement by restricting
access to specified multicast services on a switch port, and MLD throttling limits the number of simultaneous multicast groups a
port can join.
MLD filtering enables you to assign a profile to a switch port that specifies multicast groups that are permitted or denied on the
port. A 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 throttling sets a maximum number of multicast groups that a port can join at the same time. When the maximum number of
groups is reached on a port, the switch can take one of two actions; either “deny” or “replace”. If the action is set to deny, any
new MLD join reports will be dropped. If the action is set to replace, the switch randomly removes an existing group and
replaces it with the new multicast group. The MLD Snooping Port Group Filtering Configuration screen in Figure 4-8-15 appears.
