Usage Guidelines
The Immediate-Leave feature applies only to receiver ports. When the Immediate-Leave feature is
enabled, a receiver port leaves a multicast group more quickly. When the switch receives an Internet
Group Management Protocol (IGMP) leave message from a group on a receiver port, it sends an IGMP
query on that port and waits for IGMP group membership reports. If no reports are received in a
configured time period, the receiver port is removed from multicast group membership. With the
Immediate-Leave feature, an IGMP query is not sent from the receiver port on which the IGMP leave
was received. As soon as the leave message is received, the receiver port is removed from multicast group
membership, thus speeding up leave latency.
The Immediate-Leave feature should only be enabled on receiver ports to which a single receiver device
is connected.
