2.15.2 set igmp interfacemode
This command enables IGMP Snooping on all interfaces. If an interface has IGMP
Snooping enabled and you enable this interface for routing or enlist it as a member of a
port-channel (LAG), IGMP Snooping functionality is disabled on that interface. IGMP
Snooping functionality is re-enabled if you disable routing or remove port-channel
(LAG) membership from an interface that has IGMP Snooping enabled.

Mode Global Config
2.15.2.1 no set igmp interfacemode
This command disables IGMP Snooping on all interfaces.
Format no set igmp interfacemode
Mode Global Config
2.15.3 set igmp fast-leave
This command enables or disables IGMP Snooping fast-leave admin mode on a
selected interface or VLAN. Enabling fast-leave allows the switch to immediately
remove the layer 2 LAN interface from its forwarding table entry upon receiving an
IGMP leave message for that multicast group without first sending out MAC-based
general queries to the interface.
You should enable fast-leave admin mode only on VLANs where only one host is
connected to each layer 2 LAN port. This prevents the inadvertent dropping of the
other hosts that were connected to the same layer 2 LAN port but were still interested
in receiving multicast traffic directed to that group. Also, fast-leave processing is
supported only with IGMP version 2 hosts.
Default disabled
