3850 WebUI will not log in

Could someone give me a few ideas on a problem that just started.

Just bought a 3850 12XS, updated to software to Denali 16.3.2.

Logged into the WebUI. Got in fine with the default username and password. Just browsing the pages. I must have changed something because when I tried to login later it says

"Wrong Credentials. Please Login again."

I didn't think I changed anything but I must have.

Is there a way to reset the username and password or figure out what it might have changed too?

I logged into the USB management port and found the lvl15 username and password but it still does not work.

Hi

If you are using local credentials configure these lines and try again:

no aaa new-model

ip http authentication local

Hope it is useful

:-)

Thanks. Didn't seem to help. 

This is the error message using Putty connected to the USB port when I try to open the WebUI in a browser. There is no Administrator user that I can see configured.

%WEBSERVER-5-LOGIN_FAILED:Switch 1 R0/0: :  Login Un-Succe                                                              ssful from host 10.0.0.192 by user 'Administrator'

Since I just started this whole process, whats the best way to clear everything and reset the switch to factory defaults?

Thanks so much for your help

Hi

Try creating an admin user, example:

conf t

username Cisco privi 15 password Test123




>> Marcar como útil o contestado, si la respuesta resolvió la duda, esto ayuda a futuras consultas de otros miembros de la comunidad. <<

So I reset the switch to factory settings. assigned ip address etc.

The webpage again came right up. This time I added a new user. Saved Logged out

Tried to log back in with new user and it fails. It also seems slow opening the webUI, where before it opened in a snap.

here's the config, if you see anything.

Thanks so much Julio.

I tried multiple browsers on different computers. No joy.

so bizarre... I'll keep trying. When I open the WebUI for the first time it works great. There must be a parameter that's changing.

Thanks Community !

I tried with CiscoCSR1000v16.9.6; the webserver login credentials work in chrome browser but not in IE

Thanks!

Thank you, I was having the same problem because i had started configuring the switch from console.

Adding user worked for me.

Hi correctly will be:

conf t

username Cisco privi password 0 Test123

end

Good day,

 

I have a problem with the WebUI login. I have new Cisco Catalyst 3850 24. I just unboxed it. When I try to put the Login and Password I have getting the error "Wrong Credentials. Please Login again." I tried to put to username "webui" and password "S/N of the switch" and username "webui" and pass "cisco", but I cannot login.

so i have the same issue, what i can tell so far, is that something triggers when i make a change to the "ip http...." commands,

every time i change something on a command that starts like that then it lets me back into the GUI,

 

so far my best guess is that when you log out, the user is flagged as "logged out" once the switch detects that the user logged out, it seems to start a timer for "anti-logging spam" something along the lines of "you just logged out so i lock that account down for a while to prevent user spamming logins", this seems to be the symptoms, becuase when i leave the office and i try again the next day, then i can log in to the gui no problem, also if i try again by lunch time, i can get back in,

consider the following

i have aaa new-model enabled

ip http authen local

 

the ssh is fine, i can get in and out no problem, so this is a webgui issue and think it may be only a gui rule somewhere or part of the micro code

i have 3 different usernames with the same priv level and differnt passwords, so i believe tghe GUI itself locks down for a while 

when you just logged out. i dont know 100%

when i entered the "ip http client conn forceclose" command
i could see in the syslog that i get a login syslog, and then inmediately a log out syslog starting with <%WEBSERVER>
when i remove the command then the "loop" goes away and then lets me back into the device, so,
when log in again, i can see the syslog entry for login in via webserver, but when i click log out in the GUI i DO NOT SEE a
log off "%WEBSERVER" entry in the syslog,
which makes me think that the session you logged in with is still active and when you think you logged out, the switch is still waiting for a response from the "active session" and will not let you log back in untill the session times out.

i still dont have a dead on answer, but based on this observations, the switch doesn't know you logged out and it will not let you log back in with the credentials that it thinks are still active and current.
