DNA: Add Port Aggregation



This article describes the Add Port Aggregation feature of the Datto Networking Appliance (DNA).


  • Datto Networking Appliance


The Port Aggregation feature allows an operator to combine two or more NICs to act as a single logical link (LACP interface). Aggregation enables improved connection performance, as well as redundancy for inter-network traffic passing through the DNA.

To access the Port Forwarding card, log into the DNA web interface, and click Manage, as shown in Figure 1.

Figure 1: Manage

Once on the Manage page, click the Add Port Aggregation link. You will see the Add Port Aggregation card shown in Figure 2.

To add an LACP interface, enter a name for the configuration in the Description box. Then, select two or more ports to combine into a single link. Click Save Changes to save the configuration.

If you are using this feature on an appliance connected to a switch, and you make any changes to the LACP configuration on the DNA, you will need to make corresponding changes to the switch as well.

Technical Notes

  • The DNA's port aggregation feature conforms to the IEEE 802.3ad standard (LACP) and is compatible with OpenMesh / Datto Managed Networking switches.
  • An Ethernet port cannot be a member of an LACP interface and used as a standalone port at the same time.
  • The LACP interface can include 2-4 ports; you can create as many LACP interfaces as you have LAN ports available.
  • LACP interfaces are compatible with the same features as a normal standalone LAN port, such as native LANs and tagged VLANs.
