About Image Repository
Cisco DNA Center stores all of the software images and software maintenance updates (SMUs) for the devices in your network. Image Repository provides the following functions:
Image Repository—Cisco DNA Center stores all the unique software images according to image type and version. You can view, import, and delete software images.
Provision—You can push software images to the devices in your network.
Before using Image Repository features, you must enable Transport Layer Security protocol (TLS) on older devices such as Catalyst 3K, 4K, and 6K. After any system upgrades, you must re-enable TLS again. For more information, see “Configure Security for Cisco DNA Center” in the Cisco Digital Network Architecture Center Administrator Guide.
