    Posted May 24, 2018 10:15 AM

    Im seeing this in the logs when guest users are trying to MAC authenticate:

     

    mac_auth1.JPG

    It says unknow client, but when checking endpoint repository, I see this:

     

    mac_auth2.JPG

    This is found when searching the repo with the MAC address of the client. 

     

    I have just changed CP install from a old Dell branded CP, to orgininal Aruba CP. This error was also present on the old unit.

     

    Can anyone help me with this.

     

    Thanx

    J.

    You should be using [Allow All MAC Auth] as the auth method.

    I have tried out this method, alot of requests go through, some dont. 

    Why does MAC-AUTH say the klient is unknown, when its know ?

     

    The MAC-AUTH setting follow the guest template on  6.7.3.106273

     

    Just wondering.

    Your endpoint in the endpointdatabase must have a “known device” status to use mac-auth.

    That is not correct. Allow All MAC Auth should be used and handle everything in authorization. Known/Unknown is not required.

    One of my local contacts in norway tells me that they use only MAC-AUTH since this is the template default.

    It also doenst explain to me why the MAC-AUTH fail on know devices with valid attributes.
