Adding a Port to an Existing LAG

The most simple LAG configuration is a single Port LAG, which configures the device on the Megaport side to run LACP on a single channel. However, this configuration doesn’t provide any added resilience. If Port capacity or traffic status requires resilience, you can add Ports to a LAG. For example, if traffic moves from development to production, you might require additional Ports.

When you add one or more Ports to a live LAG, they are automatically assigned the same location, speed, and Marketplace visibility as other Ports in the LAG. Any Ports that you add to a diverse LAG will inherit the diversity zone of the LAG.

To add a Port to an existing LAG

  1. In the Megaport ONE Portal, choose Networking > Services.
  2. Click the gear icon Gear icon next to the LAG Port and select Add Ports to LAG.

  3. Specify the details for the new Port:

    • Port Name – Specify an easily identifiable name for the Port.
    • Ports to add to LAG – Specify the number of Ports to add to the LAG. The maximum number of Ports in a LAG is 8. The monthly price updates dynamically based on your selections.
    • Port Diversity – If the current location supports diversity, this section notifies you that the new Port will be added to the diversity zone of the LAG. For details on Port diversity, see Port Diversity.

  4. Specify the Billing Details:

    • Service Level Reference (optional) – Specify a unique identifying number for the Port to be used for billing purposes, such as a purchase order number or unique customer ID. The service level reference number appears for each service under the Product section of the invoice. You can also edit this field for an existing service.
    • Minimum Term – Specify 1 month, 12 months, 24 months, or 36 months. Longer terms result in a lower monthly rate. By default, a 12 month term is selected.


      • Partner and partner-managed accounts cannot view or change Port contract terms.
      • Partner-managed accounts can apply a Partner Deal to a LAG.
    • Promo Code – If you have a promotional code, enter it and click Add Code.

  5. Click Create Port.
