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.
•
MLD throttling can also be set on a trunk interface. When ports are
configured as trunk members, the trunk uses the throttling settings of
the first port member in the trunk.
•
If the maximum number of MLD groups is set to the default value, the
running status of MLD throttling will change to false. This means that
any configuration for MLD throttling will have no effect until the
maximum number of MLD groups is configured to another value.
