Configuring LACP

To configure LACP, you must, again, first create a LAG. The first port in the LAG serves as the logical port for the LAG. This is the reference port used in configuration commands. It can be thought of as the logical port representing the entire port group, and it serves as the LAG Group ID.

  1. Create a LAG using:
    enable sharing port grouping port_list {algorithm [address-based {L2 | L3 | L3_L4 | custom} | port-based }]} {lacp | health-check}

    The port you assign using the first parameter becomes the logical port for the link aggregation group and the LAG Group ID when using LACP. This logical port must also be included in the port list of the grouping itself.

  2. If you want to override the default prioritization in LACP for a specified LAG, use:
    configure sharing port lacp system-priority priority

    This step is optional; LACP handles prioritization using system MAC addresses.

  3. Add or delete ports to the LAG as desired using:
    configure sharing port add ports port_list
  4. Override the ports selection for joining the LAG by configuring a priority for a port within a LAG by using the command:
    configure lacp member-port port priority port_priority
  5. Change the expiry timer using:
    configure sharing port lacp timeout [long | short]

    The default value for the timeout is long, or 90 seconds.

  6. Change the activity mode using:
    configure sharing port lacp activity-mode [active | passive]

    The default value for the activity mode is active.

  7. Configure the action the switch takes for defaulted LAG ports.
    configure sharing port lacp defaulted-state-action [add | delete]

    The default value for defaulted LAG ports is delete the default ports.



Always verify the LACP configuration by issuing the show ports sharing command; look for the ports listed as being in the aggregator.
