device-name
(config)#
ip igmp snooping vlan 1 static 01:00:5e:00:01:29
interface 1/1/1,1/1/4-1/1/8
ip igmp snooping vlan immediate-leave
The
ip igmp snooping vlan immediate-leave
command, in Global Configuration mode,
enables IGMP Immediate-Leave Processing on the VLAN interface. The
no
form of this
command disables Immediate-Leave processing.
When you enable IGMP Immediate-Leave processing, 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.
