Cisco N5K backup failures

I have, by following other posts on this forum, been able to get all of my Cisco network gear backing up except our 2 Cisco N5K C56128P switches. Both of these throw "Protocol error: Expected control record". The debugging of the imccfgbakdm didn't yield anything of use aside from this same error. The seemingly 3 important lines are below:

2019-11-18 14:33:09.352 [ERROR (11)] [THREAD(4604)] [CCLIScriptProcessor::exec()] Fail to call exec_impl(). DevIP =<redacted>, AdaptName = CiscoNX7K,service name = ConfigBackup, action name = backup_startup_config.

, error_message: Timeout to login. No message recive from device!

The SSH credientials test fine and SSH proxy works as well. Any assistance would be of great help.

Hello,

I hope you are using Automatic backup to capture device configs . Please try to perform manual back-up those two switches and also let me know are you using SCP / or SFTP method to run back up.

Yes they are trying to use auto-backup and that debug output was copied from a manual backup attempt. All of our devices use SCP including the F5s which took some tom-hackery to get working.

Hi,

I sugest you to log a support case with HPE to verfify your firmware and IMC setting
