About Golden Software Images
DNA Center allows you to designate software images and software image updates (SMUs) as golden. A golden software image or SMU is an ideal image for a particular device type. Designating a software image or SMU as golden saves you time by eliminating the need to make repetitive configuration changes and ensures consistency across your devices. You can designate both an image and a corresponding SMU as golden to create a standardized image.
You cannot mark a SMU as golden unless the image to which it corresponds is also marked golden.
Provision Software Images
You can push software images to the devices in your network.
Choose Provision, then select the device whose image you want to upgrade.
From the Select Devices pulldown menu, click Update OS Image.
Click Update, then click OK to acknowledge that the device will reload after the image is upgrade.
To view the progress of the image upgrade, you can open a console session to the device.
