PRTG Manual: Selecting Configuration Capture Credentials
SSH or Telnet credentials must be provided to establish a command line terminal session. If no credentials are provided, the configuration capture will fail. When capturing configurations during discovery the credentials provided in the discovery settings will be used. When using the 'Start vs. Run' tool the credentials assigned to the device will be used. Credentials can be assigned to a device during discovery or manually. When using the Capture Configuration tool the credentials selected before beginning the configuration capture will be used.
If both SSH and Telnet credentials are available the SSH credentials will be used. If the SSH authentication fails the Telnet credentials will not be used. The assumption is that if SSH credentials are available, then secure authentication is desired. If you want Telnet credentials to be used the SSH credentials must be removed from the device.
See Managing Device Credentials for more information.
