title: Link aggregation (LACP) support for Cloudflare One Appliance
description: Bundle physical LAN ports into a single logical interface for redundancy and bandwidth.
date: 2026-04-07
products:
- cloudflare-one
---

Cloudflare One Appliance now supports Link Aggregation Control Protocol (LACP), allowing you to bundle up to six physical LAN ports into a single logical interface. Link aggregation increases available bandwidth and eliminates single points of failure on the LAN side of the appliance.

This feature is available in beta on physical appliance hardware with the latest OS. No entitlement is required.

To configure a Link Aggregation Group, refer to [Configure link aggregation groups](/cloudflare-wan/configuration/appliance/network-options/link-aggregation/).

You can bundle multiple physical LAN ports on a Cloudflare One Appliance into a single logical port called a Link Aggregation Group (LAG). This increases LAN bandwidth and provides redundancy. If a member port fails, traffic automatically shifts to the remaining ports in under one second.

:::note
Your appliance must be running OS version 2026.2.0 or later. This version deploys automatically.
:::

The following guide assumes you have already created a site and configured your Cloudflare One Appliance. For instructions, refer to <a href={props.hardConnectorURL}>Configure hardware Appliance</a> or <a href={props.virtualConnectorURL}>Configure virtual Appliance</a>.

## Create a LAG

1. Go to the **Connectors** page.

<DashButton url="/?to=/:account/magic-networks/connections" />

2. Go to the **Appliances** tab > **Profiles**.
3. Select the Cloudflare One Appliance you want to configure > **Edit**.
4. Go to the **Appliances** tab.
5. In **Link aggregation groups (LAGs)**, select **Create A LAG**.
6. Select the LAN ports you want to bundle. You can add up to six ports per LAG. All ports must be the same type and speed.
7. Select **Save**.

## Assign a LAN to a LAG

1. Go to the **Connectors** page.

<DashButton url="/?to=/:account/magic-networks/connections" />

2. Go to the **Appliances** tab > **Profiles**.
3. Select the Cloudflare One Appliance you want to edit > **Edit**.
4. Go to **Network Configuration** > **LAN configuration**.
5. Select or create a LAN > **Edit**.
6. In **Interface** > **Interface type**, select **Aggregate** as your LAG instead of a single port.
7. Select **Save**.

## Monitor LAG status

1. Go to the **Connectors** page.

<DashButton url="/?to=/:account/magic-networks/connections" />

2. Go to the **Appliances** tab > **Profiles**.
3. Select the Cloudflare One Appliance > **Edit**.
4. Go to the **Appliances** tab.

The page displays each configured LAG and the status of its member ports.

## Delete a LAG

1. Go to the **Connectors** page.

<DashButton url="/?to=/:account/magic-networks/connections" />

2. Go to the **Appliances** tab > **Profiles**.
3. Select the Cloudflare One Appliance > **Edit**.
4. Go to the **Appliances** tab.
5. Next to the LAG you want to delete, select the three-dot menu > **Delete**.
6. Select **Delete**.
