It takes some time to boot up again, after that you can see the new Version is running

Switch Ports Model              SW Version        SW Image              Mode
------ ----- -----              ----------        ----------            ----
*    1 32    WS-C3850-24P       Denali 16.1.1     CAT3K_CAA-UNIVERSALK9 INSTALL

After that i created a user with priv 15

Switch(config)#username cisco privilege 15 secret cisco

Now you can head to the new WebGui, i attached two impressions of the new GUI. Compared to the old cisco switch GUIs it looks really nice. But if it ever is used?… 🙂
