Configuring Vlan Settings For Igmp Snooping And Query - AMX NXA-ENET8-2POE Operation/Reference Manual

Port Related Configuration (Cont.)
• Throttling
If multicast routing is not supported on other switches in your network, you can use IGMP Snooping and
IGMP Query to monitor IGMP service requests passing between multicast clients and servers, and
dynamically configure the switch ports which need to forward multicast traffic.
Multicast routers use information from IGMP snooping and query reports, along with a multicast routing
protocol such as DVMRP or PIM, to support IP multicasting across the Internet.

Configuring VLAN Settings For IGMP Snooping And Query

Use the IGMP Snooping VLAN Configuration page to configure IGMP snooping and query for a VLAN
interface.

Limits the number of multicast groups to which a port can belong. (Range: 1-10;
Default: unlimited)
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, any
new IGMP join reports will be dropped.
VLAN Identifier.
face to determine which hosts want to receive multicast traffic. (Default: Enabled)
When IGMP snooping is enabled globally, the per VLAN interface settings for
IGMP snooping take precedence. When IGMP snooping is disabled globally,
snooping can still be configured per VLAN interface, but the interface settings will
not take effect until snooping is re-enabled globally.
When enabled, the switch can serve as the Querier (on the selected interface),
which is responsible for asking hosts if they want to receive multicast traffic.
(Default: Disabled)
A router, or multicast-enabled switch, can periodically ask their hosts if they want
to receive multicast traffic. If there is more than one router/switch on the LAN per-
forming IP multicasting, one of these devices is selected querier and assumes the
role of querying the LAN for group members. It then propagates the service
requests on to any upstream multicast switch/router to ensure that it will continue
to receive the multicast service. This feature is not supported for IGMPv3 snoop-
ing.
