Configuring Fast Leave for Member Ports

Configuring Fast Leave for Member Ports


When the switch receives IGMP Leave messages from a group member port, fast leave allows the switch to immediately delete forwarding entries of the member port but does not reset the aging timer.

  • Enable fast leave in a VLAN only when each interface in the VLAN is connected to one receiver host.

  • Fast leave takes effect for member ports in a VLAN only when the switch can process IGMPv2 messages.


  1. Run system-view

    The system view is displayed.

  2. Run vlan vlan-id

    The VLAN view is displayed.

  3. Run igmp-snooping prompt-leave [ group-policy acl-number ]

    Fast leave is configured for group member ports in the VLAN.

    By default, no member port is allowed to fast leave a multicast group.

    If you do not specify group-policy when configuring fast leave, this function takes effect for all groups. For details on how to configure an ACL, see ACL Configuration in the S600-E V200R012C00 Configuration Guide - Security.
