IGMP snooping
Enable or disable IGMP snooping in the VLAN.
You can proceed with the subsequent configurations only if Enable is selected.
Version
By configuring an IGMP snooping version, you configure the versions of IGMP
messages that IGMP snooping can process.
• IGMP snooping version 2 can process IGMPv1 and IGMPv2 messages, but
not IGMPv3 messages, which will be flooded in the VLAN.
• IGMP snooping version 3 can process IGMPv1, IGMPv2, and IGMPv3
messages.
IMPORTANT:
If you change IGMPv3 snooping to IGMPv2 snooping, the system clears all IGMP
snooping forwarding entries that are dynamically added.
