So I'm pretty decent with Cisco gear. Been around it for a while, but this issue is downright perplexing to me.
We took over for another company who did some major changes this last summer. Unfortunately, we took over right after they made the changes so we don't know much of what they did, and they turned over zero documentation.
The issue is that randomly, it seems, the switches will suddenly be missing things like a route or a vlan access stmt on one of the trunk ports.
One thing we did find is that it appears they were backing up conifgs to a Solarwinds TFTP server, but all of that stopped after they did their reorg in July because all of the config files are dated June of 2017.
on top of that it appears they had tried to execute a pwd recovery on several switches and renamed the config file as config.txt instead of config.text. They must have had everything running in system run config, and then when rebooted, the autoinstall found the tftp server and pulled down the configs.
Well now we have shutoff the tftp server and disabled the service, yet we are still seeing this behavior.
My only guesses are these switches are just now rebooting for the 1st time since the July changes occured and have lost their config.
There is some other automated process that is overwriting the config.
Or, lastly, some asshole is playing a sick prank on us! ;-)
Anyone have any thoughts on this?
