Switching Commands

v1.0, July 2009
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.
no set igmp interfacemode
This command disables IGMP Snooping on all interfaces.
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.
