Configuring OVHcloud Link Aggregation in the OVHcloud Control Panel

Find out how to enable OVHcloud Link Aggregation in the OVHcloud Control Panel

Objective

OVHcloud Link Aggregation (OLA) technology is designed by our teams to increase your server’s availability, and boost the efficiency of your network connections. In just a few clicks, you can aggregate your network cards and make your network links redundant. This means that if one link goes down, traffic is automatically redirected to another available link.
Aggregation is based on IEEE 802.3ad, Link Aggregation Control Protocol (LACP) technology.

This guide explains how to configure OLA in the OVHcloud Control Panel.

Requirements

  • A dedicated server from the Advance, Scale, or High Grade ranges in your OVHcloud account
  • An Operating System / Hypervisor that supports the 802.3ad aggregation protocol (LACP)

OVHcloud Control Panel Access

  • Direct link:
  • Navigation path: Bare Metal Cloud > Dedicated servers > Select your server

Instructions

Warning

OLA is configured on all network interfaces. They will form a “private aggregation”.

Following the implementation of OLA, the public IP will no longer be accessible.

Configuring OLA in the OVHcloud Control Panel

To start configuring OLA, open the Network interfaces tab on your server's management page.

Click the Network Aggregation button in the Network Interface Controllers (NICs) section.

You will be shown two tables:

  • On the left, the current configuration of your network interfaces;
  • On the right, the simulated configuration of your aggregated network interfaces.

In the field below the tables, enter a name for your link aggregation.

Once you have verified that the aggregation layout matches your network requirements, click Enable Aggregation to proceed.

This may take a few minutes. Once it is complete, the next step is to configure the interfaces in your operating system via a NIC link or NIC team. For the method to use, refer to the following guides for the most popular operating systems:

Checking the OLA status

You can verify your Link Aggregation (OLA) status in the Network interfaces tab. At the bottom of the Bandwidth section, locate the OVHcloud Link Aggregation row.

There are four possible status tags:

  • Unavailable: OLA is not supported on this dedicated server model.
  • Available: OLA is supported but is not configured.
  • Active - Fully Private: OLA is enabled; all physical interfaces are aggregated into a single private link for vRack use.
  • Active - Double LAG: OLA is pre-enabled; physical interfaces are split into two separate aggregates (one public, one private).
Info

Note: The Active - Double LAG status is a specific configuration typically reserved for Scale and High-Grade server ranges, which feature four physical network interfaces.

Restoring OLA to default values

To restore OLA to the default values, click on the Disaggregate networks button at the top of the Network Interface Controllers section. Click Confirm in the popup menu.

This may take a few minutes.
