How to take sFTP failed logs on cucm

[hasunm522]

When I 'm trying to add a backup device under DRS it fails with an error (update failed : unable to access sftp server. Please ensure the username and password are correct.)

I need to find the logs for the issue. Can I collect logs for sftp in RTMT. ???

If you want to look at the specific protocol and what happens, you'd need a packet capture.

Along with packet captures pull simultaneous DRF master and local logs to see from an application point of view on what happens when the SFTP connection is tried to be established.
