Removing Supplementary Network Interfaces

Scenario

You can remove supplementary network interfaces from a backend server group if you do not need them to process requests.

Notes

After the backend server is removed, requests are still routed to it. This is because a persistent connection is established between the load balancer and the backend server and requests are routed to this server until the TCP connection times out.

If no data is transmitted over this TCP connection after it times out, ELB disconnects the connection.

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.
6. Switch to the Backend Servers tab page and click Supplementary Network Interfaces.
7. Select the supplementary network interfaces and click Remove above the list.
8. In the displayed dialog box, click Yes.
