Detaching a Network Interface

Scenarios

An ECS can have a maximum of 12 network interfaces, including a primary network interface that cannot be detached. This section describes how to detach an extension network interface.

Detaching a network interface may cause network interruptions. Evaluate the impact in advance and exercise caution when performing this operation.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and project.
  3. Under Computing, click Elastic Cloud Server.
  4. In the ECS list, click the name of the ECS from which you want to detach a network interface

    The ECS details page is displayed.

  5. On the Network Interfaces tab, locate the target network interface and click Detach.

    You are not allowed to detach the primary network interface (the first one displayed in the network interface list).

  6. In the displayed dialog box, click OK.

    Certain ECSs do not support network interface detachment when they are running. For details, see the GUI display. To detach a network interface from such an ECS, stop the ECS first.
