Enabling IGMP Immediate Leave
When you enable IGMP Immediate Leave, the switch immediately removes a port when it detects an IGMP
Version 2 leave message on that port. You should use the Immediate-Leave feature only when there is a single
receiver present on every port in the VLAN.
Immediate Leave is supported only on IGMP Version 2 hosts. IGMP Version 2 is the default version for
the switch.
