  • periodic—Interval for periodic transmission of LACP packets. The options are:

    • fast—Transmit link aggregation control PDUs every second.

    • slow—Transmit link aggregation control PDUs every 30 seconds.

  • Default: If you do not specify lacp as either active or passive, LACP remains off (the default).

The remaining statements are explained separately. See CLI Explorer.
