• IGMP Snooping
• IGMP Interface Settings
• IGMP VLAN Settings
•IGMP Proxy
IGMP Snooping
To support selective IPv4 Multicast forwarding, bridge Multicast filtering must be enabled (in
the Properties page), and IGMP Snooping must be enabled globally and for each relevant
VLAN in the IGMP Snooping page.
To enable IGMP Snooping and identify the device as an IGMP Snooping Querier on a VLAN:
STEP 1 Click Multicast > IPv4 Multicast Configuration > IGMP Snooping.
When IGMP Snooping is globally enabled, the device monitoring network traffic can
determine which hosts have requested to receive Multicast traffic. The device performs IGMP
Snooping only if both IGMP snooping and Bridge Multicast filtering are enabled.
The IGMP Snooping Table is displayed. The fields displayed are described in the Edit page
below. In addition the following fields are displayed:
• IGMP Snooping Status—Displays whether IGMP Snooping was enabled
(Administrative) and whether it is actually running on the VLAN (Operational).
• IGMP Querier Status—Displays whether IGMP Querier was enabled
(Administrative) and whether it is actually running on the VLAN (Operational).
Enable or disable the following features:
• IGMP Snooping Status—Select to enable IGMP snooping globally on all interfaces.
• IGMP Querier Status—Select to enable IGMP querier globally on all interfaces.
