Enabling IGMP Immediate-Leave Processing
When you enable IGMP Immediate-Leave processing, the EtherSwitch HWIC immediately removes a
port from the IP multicast group when it detects an IGMP version 2 Leave message on that port.
Immediate-Leave processing allows the switch to remove an interface that sends a Leave message from
the forwarding table without first sending out group-specific queries to the interface. You should use the
Immediate-Leave feature only when there is only a single receiver present on every port in the VLAN.
Use the following steps to enable IGMP Immediate-Leave processing.
