Hi, I've upgrade as you told me to do.
But when i Try to upgrade to 15.1 and then reboot I cannot connect via ssh or via telnet to the device.
Fortunately I had the j-web activated and from there I managed to enter the apparatus. I made a "Reboot" of the machine from there and then everything started up again. Same procedure done for other 5 switches and all the same problem. Why does this happen? Or that the ssh does not come up? Also from the 15.1 to the 17.3 same problem. Something that did not happen from 13.2 to 14.1
What's the problem?
