Adding Supplementary Network Interfaces

Scenario

In addition to cloud servers and on-premises servers, you can add supplementary network interfaces to a backend server group.

Supplementary network interfaces allow you to configure more NICs than a cloud server would normally support. They can be attached to VLAN subinterfaces of elastic network interfaces.

For details on how to create a VPC, see the Virtual Private Cloud User Guide.

Constraints and Limitations

Supplementary network interfaces can only be added to a hybrid backend server group.

Procedure

  1. Log in to the management console.
  2. In the upper left corner of the page, click and select the desired region and project.
  3. Hover on in the upper left corner to display Service List and choose Networking > Elastic Load Balance.
  4. In the navigation pane on the left, choose Elastic Load Balance > Backend Server Groups.
  5. On the Backend Server Groups page, click the name of the backend server group that you want to add supplementary network interfaces to.
  6. Switch to the Backend Servers tab page and click Add on the Supplementary Network Interfaces area.

    You can search for supplementary network interfaces by ID, private IP address, network interface private IP address, subnet name, or subnet ID.

  7. Specify the weights and ports for the supplementary network interfaces and click Finish.
