    Hello

     

    i have a very strange issue and i guess i have something configured wrong. 

     

    Here is my 802.1x config, pretty basic:

     

    aaa port-access gvrp-vlans
    aaa port-access authenticator 2/43-2/44
    aaa port-access authenticator 2/43 client-limit 10
    aaa port-access authenticator active
    aaa port-access mac-based 2/43
    aaa port-access mac-based 2/43 unauth-vid 2
    aaa port-access 2/43 mixed

    when i plugin a phone on Port 2/43, Phone boots to proper VLAN (provided by Radius):

    show port-access mac-based clients 2/43 detailed
    
    Port Access MAC-Based Client Status Detailed
    
    Client Base Details :
    Port                : 2/43
    Client Status       : authenticated         
    Session Time        : 182 seconds
    MAC Address         : FFFFFF-5cc306         
    Session Timeout     : 0 seconds
    IP                  : n/a
    
    Access Policy Details :
    COS Map            : Not Defined           
    In Limit Kbps      : Not Set
    Untagged VLAN      : Not Set               
    Out Limit Kbps     : Not Set
    Tagged VLANs       : 30
    Port Mode          : 1000FDx               
    Auth Mode          : User-based
    RADIUS ACL List    : No Radius ACL List

    ok, next step is to connect a laptop with Windows Service "dot3svc" enabled, which works properly as well:

     

    Client Base Details :
    Port            : 2/43
    Client Status   : Authenticated
    Session Time : 1160 seconds Client name : host/XX-XX-XX.XX...
    Session Timeout : 0 seconds IP : n/a
    MAC Address : FFFFFF-4664aa
    Access Policy Details : COS Map : Not Defined
    In Limit Kbps : Not Set Untagged VLAN : 10
    Out Limit Kbps : Not Set Tagged VLANs : No Tagged VLANs Port Mode : 1000FDx RADIUS ACL List : No Radius ACL List

    So both are connected properly:

    show port-access clients
    Port Access Client Status Port Client Name MAC Address IP Address Type VLAN 2/43 FFFFFF-5c.. n/a 8021X 30 2/43 host/XX-.. FFFFFF-46.. n/a 8021X 10 2/43 FFFFFF5c.. FFFFFF-5c.. n/a MAC 30 2/43 FFFFFF-46.. n/a MAC 10

    next step is to disable Windows Service "dot3svc" which should place the client in the "unauth-vid 2", works again as expected:

     

    show port-access mac-based clients 2/43 detailed
    
    Port Access MAC-Based Client Status Detailed
    
    Client Base Details :
    Port            : 2/43
    Client Status   : rejected,unauth vlan
    Session Time : 25 seconds MAC Address : 186024-4664aa
    Session Timeout : 0 seconds IP : n/a Access Policy Details : COS Map : Not Defined
    In Limit Kbps : Not Set Untagged VLAN : 2
    Out Limit Kbps : Not Set Tagged VLANs : No Tagged VLANs Port Mode : 1000FDx
    Auth Mode : User-based RADIUS ACL List : No Radius ACL List

    But when i connect the phone (which authenticated successfully with MAC) and behind the phone a client with Windows Service "dot3svc" disabled, following happens:

     

     

     

     show port-access mac-based clients 2/43 detailed
    
     Port Access MAC-Based Client Status Detailed
    
    Client Base Details :
    Port            : 2/43
    Client Status   : authenticated
    Session Time : 230 seconds MAC Address : 00085d-5cc306
    Session Timeout : 0 seconds IP : n/a Access Policy Details : COS Map : Not Defined
    In Limit Kbps : Not Set Untagged VLAN : Not Set
    Out Limit Kbps : Not Set Tagged VLANs : 30 Port Mode : 1000FDx
    Auth Mode : User-based RADIUS ACL List : No Radius ACL List Client Base Details : Port : 2/43 Client Status : rejected no vlan
    Session Time : 45 seconds MAC Address : 186024-4664aa
    Session Timeout : 0 seconds IP : n/a Access Policy Details : COS Map : Not Defined
    In Limit Kbps : Not Set Untagged VLAN : Not Set
    Out Limit Kbps : Not Set Tagged VLANs : No Tagged VLANs Port Mode : 1000FDx
    Auth Mode : User-based RADIUS ACL List : No Radius ACL List

    for some reason the client does not get the unauth-vlan assigned, instead "Client Status : rejected no vlan"

     

    Anyone an idea what i am missing?

     

    thanks a lot in advance

    why don't enable client-limit for mac-auth too ?

     

    What do you have on log ?

     

    (what the radius server ?)

    Hi 

     

    sorry for my very late reply, solution was to activate "mixed mode" on ports:

    aaa port-access 1/1 mixed

     

    Thanks for your support!
