Specifying an IGMP snooping version
About IGMP snooping versions
Different IGMP snooping versions process different versions of IGMP messages.
IGMPv2 snooping processes IGMPv1 messages, IGMPv2 messages, and IGMPv3 queries, but it floods IGMPv3 reports in the VLAN or VSI instead of processing them.
IGMPv3 snooping processes IGMPv1, IGMPv2, and IGMPv3 messages.
Restrictions and guidelines
If you change the IGMP snooping version from 2 to 3, the device performs the following actions:
Clears all IGMP snooping forwarding entries that are dynamically created.
Keeps static IGMPv3 snooping forwarding entries (*, G).
Clears static IGMPv3 snooping forwarding entries (S, G), which will be restored when the IGMP snooping version is switched back to 3.
For more information about static IGMP snooping forwarding entries, see "Configuring a static member port."
