Important Points to Remember for IGMP Snooping
• Dell Networking OS supports version 1, version 2, and version 3 hosts.
• Dell Networking OS IGMP snooping implementation is based on IP multicast address (not based on
Layer 2 multicast mac address) and the IGMP snooping entries are in Layer 3 flow table not in Layer 2
forwarding information base (FIB).
• Dell Networking OS IGMP snooping implementation is based on draft-ietf-magma-snoop-10.
• Dell Networking OS supports IGMP snooping on JUMBO-enabled cards.
