This is the case even after upgrading the firmware (including the ssh.xmod) and disabling and reenabling ssh. I've even tried providing a pregenerated key. (and saving before rebooting of course).<BR /> <BR /> After upgrading several switches, using the same procedure for all of them, one of those switches is now also exhibiting this symptom, while the rest all went fine. The new switch in question was upgraded from 15.3.1.4 to 15.3.2.11p1-2, and ssh was working fine before the upgrade.<BR /> <BR /> Is the key stored in a particular (apparently hidden) file?
