    I am unable to log in using GUI but can authenticate SSH fine. This is the case with the 2620, 2920, 2930.

    Any suggestions? We have a mixed aruba managed, aruba standalone environment.

    Hi

    can you please elaborate a bit more on what "unable to log in using GUI" exactly means? Is the web GUI showing up or is perhaps the web server disabled? Can you log in but without administrative access or is your user denied login at all? 

    Are you trying with a local account or RADIUS/TACACS remote auth?

    Kindly, share the running configuration of your switch, with focus of RADIUS/TACACSs and/or "aaa" parts, so we can see what is configured and help you identifying the issue you have. 

    Regards, 
    Thomas

    I can log in SSH using local manager creds. Radius and aaa are not configured in the config. The web login loads, but will not accept the manager creds. So the web server is not disabled, but the creds are not being relayed to the switch, something like that. 

    hostname "xxxxxxxxxxxx"
    max-vlans 64
    time timezone -300
    time daylight-time-rule Continental-US-and-Canada
    no qos dscp-map 101110
    trunk 26 Trk1 Trunk
    ip default-gateway 10.180.30.1
    vlan 1
       name "Default"
       untagged 25,27-28,Trk1

    etc etc

    Okay, that sounds a bit strange. To double check, could you please run the following commands and post the output?

    • show authentication
    • show web-management
    • show version
    • show time
    • show run | in password
    • show run | in aaa

     

    Please sanitize any confidential information but do not remove any entire lines from the output.

     

    Moreover, try a login on the web and have a look at the switch's log:

    • show log -r

    Please post any message that has to do with the login attempt.

     

    Regards,

    Thomas

    So, you have multiple problems:

    • your time setting is wrong --> 1990. Make sure you set an accurate time and also sync time using NTP
    • you have configured RADIUS login but your RADIUS servers are not reachable. Make sure your RADIUS servers are reachable or switch to local login "aaa authen web login local" and "aaa authen ssh login local". 
    • your software is super old ... on what type of switch did you run the command?

    I hope this helps.

    These incorrect settings would impact web authentication (local creds)?

    Well, at least I would correct the aaa settings to use local login if RADIUS is entirely not available. Did you configure RADIUS tracking, so dead RADIUS server are kicked out of the authentication sequence?
    For local login, time is not a problem unless dealing with certificates (not sure whether or not you are using HTTP or HTTPS to access your web server).
