MLD snooping port group filtering
In certain switch applications, the administrator may want to control the multicast
services available to end users (such as an IP/TV service based on a specific
subscription plan, for example). 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.
The MLD Snooping Port Filtering Profile Configuration page permits assigning 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.
However, 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.
