IGMP Snooping Commands

Important Points to Remember for IGMP Snooping
• The Dell Networking OS supports version 1, version 2, and version 3 hosts.
• The 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).
