RPD Secure Software Download
The cnBR Manager provides automated ways to securely download and activate software images to RPDs.
The secure software download (SSD) feature helps you to authenticate the source of a file and verify the integrity of the downloaded code before you use it in your system. The SSD feature is applicable to Remote PHY (R-PHY) devices installed in unsecure locations.
Prerequisites
To use SSD, the following prerequisites must be met:
-
For Non-Express mode: The RPD software image is available at an external TFTP or HTTP image server. The image server is where the software image is stored, and can be accessed by RPD.
-
For Express mode: The RPD software image is available in the Cisco Operations Hub. Ensure that RPD has connectivity to the management IP of Cisco Operations Hub.
-
Ensure that code validation certificates are available. For more information, go through the Add Code Validation Certificates topic.
