Is there such thing as the SSH 'Known Hosts' file (or equivalent) used by NCM to connect to devices.
I had successfully managed a large group of devices and scheduled a job to collect the configs nightly. However, this job is starting to fail to retrieve configs. I think that this may be related to the fact the devices are being upgraded (OS), and after upgrade, using a new SSH key/cert. (I need to confirm this is the case).
I was going to remove some devices from NCM and then re-add in an attempt to allow NCM to discover from afresh, but this would mean that all config history is lost and i would like to avoid that.
Please can someone advise whether NCM does use some form of known hosts, or if there may be another option without removing from NCM..
