periodic (Interfaces)


Hierarchy Level


For redundant Ethernet interfaces in a chassis cluster only, configure the interval at which the interfaces on the remote side of the link transmit link aggregation control protocol data units (PDUs) by configuring the periodic statement on the interfaces on the local side. It is the configuration on the local side that specifies the behavior of the remote side. That is, the remote side transmits link aggregation control PDUs at the specified interval.


  • fast—Transmit link aggregation control PDUs every second.

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

  • Default: fast
