Usage Information Queriers normally send some queries when a leave message is received prior to deleting a group from the

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.

not forward the packets to multicast router ports. On the C-Series and S-Series, in order to disable Layer 2
multicast ooding, disable Layer 3 multicast (no ip multicast-routing).
