Device Auxiliary / Secondary NIC settings

Topic

This article describes the uses and configurations of auxiliary NICs on the datto device.

Environment

  • Datto SIRIS

Description

This article shows you how and why to use the auxiliary NICs of a Datto device. Full networking requirements and a breakdown of the settings in the Network Configurations page are covered in the Additional Resources section.

To configure a Datto device's networking, click on the Configure tab in the device GUI, Then, select Networking from the drop-down menu.

Use Cases

Auxiliary NICs are used for the following operations:

  • NIC bonding
  • Protecting of machines on a separate subnet from the primary connection with no route in place
  • Separate NIC for a virtual machine hosted on the Datto appliance
  • Connecting to other Datto devices directly for a NAS Roundtrip or a device migration.

Best practices for auxiliary NICs on Datto SIRIS devices:

  • Connect only the NICs intended for active use.
  • Do not enable NICs without a network connected; enabling and configuring unconnected auxiliary NICs may cause networking issues.

NOTE  Hyper-V virtualizations cannot use the auxiliary NIC for their offload method; they must use the primary NIC.
