IGMP Snooping version 2 and 3 are supported on the switch.
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).
• The IGMP snooping implementation is based on draft-ietf-magma-snoop-10.
• The system supports IGMP snooping on JUMBO-enabled cards.
• IGMP snooping is not enabled by default on the switch.
• A maximum of 1800 groups and 600 VLAN are supported.
• IGMP snooping is not supported on a default VLAN interface.
• IGMP snooping is not supported over VLAN-Stack-enabled VLAN interfaces (you must disable IGMP
snooping on a VLAN interface before configuring VLAN-Stack-related commands).
• IGMP snooping does not react to Layer 2 topology changes triggered by spanning tree protocol (STP).
• IGMP snooping reacts to Layer 2 topology changes multiple spanning tree protocol (MSTP) triggers by
sending a general query on the interface that comes in the FWD state.
