IGMP Snooping Commands
Dell Networking OS supports IGMP Snooping version 2 and 3 on all Dell Networking systems.
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.
• 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).
ip igmp snooping enable
Enable IGMP snooping on all or a single VLAN. This command is the master on/off switch to enable IGMP
snooping.
Syntax ip igmp snooping enable
To disable IGMP snooping, use the no ip igmp snooping enable command.
