I have upgraded Cisco Switch C3850 to version 16.9.4 and after that when I tried login to switch user mode password worked but I am not able to go in enable mode and getting message "No Password Set".
As the password is already set on the switch and before the upgrade I am able login to the switch. Even before upgrade I have saved all config on the switch but not sure why I am getting this error.
Can anyone please help me to get resolve this issue.
your best (and fastest) option is probably to perform a password recovery:
