Configuring IGMP
Filtering and
Throttling for
Interfaces
Use the Multicast > IGMP Snooping > Filter (Configure Interface) page to assign and
IGMP filter profile to interfaces on the switch, or to throttle multicast traffic by
limiting the maximum number of multicast groups an interface can join at the
same time.
Note:
A single table maintains a maximum of 511 entries learned for both IGMP
and MLD snooping.
Command Usage
IGMP 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 IGMP 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.
Parameters
These parameters are displayed:
Interface – Port or trunk identifier.
An IGMP profile or throttling setting can be applied to a port or trunk. When
ports are configured as trunk members, the trunk uses the settings applied to
the first port member in the trunk.
