Usage
Information
Queriers normally send some queries when a leave message is received prior to deleting a
group from the membership database. There may be situations when you require a fast
deletion of a group. When you enable IGMP fast leave processing, the switch removes an
interface from the multicast group as soon as it detects an IGMP version 2 leave message on
the interface.
