2.2.3 Enabling IGMP Fast Leave
Normally, when receiving an IGMP Leave message, Switch does not immediately
remove the port from the multicast group but sends an IGMP group-specific query
message. If no response is received in a given period, it then removes the port from the
multicast group.
If IGMP fast leave processing is enabled, when receiving an IGMP Leave message,
Switch immediately removes the port from the multicast group. When a port has only
one user, enabling IGMP fast leave processing on the port can save bandwidth.
