SDN image: An SDN image encapsulates an SDN software and can be used to create SDN instances.

On the main menu of ZStack Cloud, choose Resource Center > Network Resource > SDN Device > SDN Image. On the SDN Image page, click Add SDN Image. Then, the Add SDN Image page is displayed.

On the displayed page, set the following parameters:

• Name: Enter a name for the SDN image.
• Description: Optional. Enter a description for the SDN image.
• Image Usage: Display SDN instance.
• CPU Architecture: Select a CPU architecture for the SDN image. SDN instances created from the SDN image inherit this architecture.
• OS: Select a OS for the SDN image. Supported OS types vary from different CPU architecture.
• Image Storage: Select an image storage to store the SDN image.
• Image Path: Enter a URL or upload a local file.
  • URL: Enter the download URL of the SDN image.
  • Local File: Upload an SDN image that can directly be accessed by the browser.
    Note: A local browser will serve as a transmission relay used for uploading the image. Do not refresh or stop the current browser, nor stop your management node. Otherwise, you will fail to add the image.

On the main menu of ZStack Cloud, choose Resource Center > Network Resource > SDN Device > SDN Image. Then, the SDN Image page appears.

The following table lists the actions that you can perform on an SDN image.

Action	Description
Add SDN Image	Add an SDN image.
Edit Name and Description	Edit the name and description of an SDN image.
Enable SDN Image	If enabled, the SDN image is available as a candidate when you create an SDN instance.
Disable SDN Image	If disabled, the SDN image is no longer available as a candidate when you create an SDN instance.
Delete SDN Image	Delete an SDN image. Note: Deleting an SDN image may cause SDN instance creation failure. Proceed with caution. If an SDN image is referenced by an SDN cluster, then you cannot delete the SDN image. Delete the SDN cluster first before performing this action.
