IPv4 Multicast Configuration
The following pages configure IPv4 Multicast Configuration:
• IGMP Snooping Configuration
• IGMP VLAN Settings
IGMP Snooping Configuration
To support selective IPv4 Multicast forwarding, bridge Multicast filtering must be
enabled (in the Multicast > Properties page), and IGMP Snooping must be enabled
globally and for each relevant VLAN in the IGMP Snooping pages.
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.
STEP 2 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.
STEP 3 To configure IGMP proxy on an interface, select a static VLAN and click Edit. Enter
the following fields:
• IGMP Snooping Status—Select to enable IGMP Snooping on the VLAN.
The device monitors network traffic to determine which hosts have asked to
be sent Multicast traffic. The device performs IGMP snooping only when
IGMP snooping and Bridge Multicast filtering are both enabled.
