Table 79 IGMP Setup
LABEL DESCRIPTION
IGMP Mode Select Enable_IGMP_Snooping to have the system passively learn multicast groups.
Select Enable_IGMP_Proxy to have the system proxy multicast traffic.
Select Disable to have the system not use either IGMP proxy or snooping.
IGMP Version Select which version of IGMP you want the system to support.
With IPv4, select IGMPv2 or IGMPv3. If you select IGMPv2, the system discards IGMPv3
packets. This provides better security if none of the devices in the network use IGMPv3. If
you select IGMPv3, the system recognizes both IGMPv2 and IGMPv3.
With IPv6, select MLDv1 or MLDv2. If you select MLDv1, the system discards MLDv2
packets. This provides better security if none of the devices in the network use MLDv2. If you
select MLDv2, the system recognizes both MLDv1 and MLDv2.
