I finally found that I can use the xmladmin/xmladmin account to login. This one was reset with the 15 second push on reset button. Whit this account, I can change the admin password. Thank you for your reply!
I whooped with joy when I was able to login using xmladmin on the switch. Thank you
@Veers! Very helpful.
I had experienced the same issue with SX6036F last month. For my case, it looks that 15 seconds were not enough.
After struggling for a couple of days, I could reset the admin password by pushing the reset button for a couple of minutes patiently.
I then put on a podcast, opened a tty console and held down the reset button. about three minutes later I saw in the console that the admin password reset was successful (see screenshot).
I continued to hold the button while the switch finished booting (another four minutes) and was able to sign into the admin account without a password prompt. Only then did I release the reset button, which prompted another restart. 7 minutes later I am able to login using admin, no password prompt.
I love this forum. Thanks again
@kaz and
@Veers for your quick responses! I've done a longer-form response with screenshots so the next poor soul can benefit.
