Configure link aggregation groups

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.

The following guide assumes you have already created a site and configured your Cloudflare One Appliance. For instructions, refer to Configure hardware Appliance or Configure virtual Appliance.

Create a LAG

  1. Go to the Connectors page.
Go to Connectors
  1. Go to the Appliances tab > Profiles.
  2. Select the Cloudflare One Appliance you want to configure > Edit.
  3. Go to the Appliances tab.
  4. In Link aggregation groups (LAGs), select Create A LAG.
  5. 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.
  6. Select Save.
