The device is showing an error when trying to launch the Express Setup window.
I just acquired a Cisco 3850-48 switch and was following this manual to get it operational: https://www.cisco.com/c/en/us/td/docs/sw...gfId-66590. I ran into an issue where I can't open the Express Setup window after entering 10.0.0.1. When I tried clearing any preconfigured settings repeatedly, restarted the switch, swapped cables, and toggled DHCP status, nothing worked. I’m stuck. I can still reach the console via Putty, which might be useful. Any suggestions?
I attempted that, but it failed. Cisco clearly advises against it since the switch functions as a DHCP server during configuration.
The latest software version appears to be 03.02.02.SE. There were issues with Chrome warning about unsafe connections and outdated TLS settings. After fixing the security problem by turning on SSL 3.0, I encountered a prompt for a username and password, but the usual one didn't work. (Approximate translation from German) I'm trying to figure out what's happening and see if a fix is possible... EDIT2: Once resolved, it asked for login credentials, which the default password didn't accept. Great x.x
Here are some possible usernames and passwords you might have tried:
- cisco/cisco admin/admin
- admin admin
- admin admin/cisco
- cisco/admin
You can also attempt the username alone if no password was set.
I also attempted to reset the switch, which cleared the NVRAM and appeared successful. At least now I’m prompted for a password when entering enable in the console, and it seems Cisco is using the correct one. It might have been an outdated configuration or something similar. However, I can’t access the web interface anymore. Thanks for sharing the list of username/password pairs—I’ll try them once I’m back online. EDIT: None of the entries worked; the system mentions "level_15_or_view_access." Not sure what that refers to.
If you can connect using PuTTY, executing "show run" and sharing the complete result here would be helpful. This lets us verify whether the device has been restored to its original state. The main concern, though, is whether you intend to use the switch—likely the CLI is the simpler approach.
I don't possess detailed strategies. I acquired it mostly for free and am now utilizing it to deepen my understanding of networking. I plan to apply it later for a home setup (just for fun). The CLI option seems adequate, but I'd favor the web version if possible. Since there was no "show run" command, I resorted to using "show running-config".
That should be what you intended: Switch#show running-config

Switching to web interface would be preferable if it runs smoothly.
