Enabling fast leave mode on a port

Enable fast (immediate) leave mode to specify if a port receives a leave message from a member of a group. If you enable fast leave mode on a port, it uses the global fast leave mode configuration.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

    Note

    Note

    If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

  2. Enable fast leave:

    ip igmp immediate-leave
