  • 1.  role doesn't apply after passed stateful-802.1x

    Posted Jun 25, 2012 03:17 AM

     

     

    Hi all,

       I have some problem about WLAN controller and 3th party AP. I connected AP to Aruba interface and config it as untrusted port then I connected PC with 802.1x authentication after passed authentication Aruba controller didn’t apply role from radius response its got the default role from stateful-dot1x configuration.

     

    interface gigabitethernet  1/3        
    description "GE1/3"       
    trusted vlan 1-4092      
    switchport mode trunk

     

    aaa authentication-server radius "IAS"

       host "172.20.43.131"

       key xxxxxx

     

    aaa server-group "3th_AP"

     auth-server IAS

     set role condition Reply-Message contains "pidgroup" set-value pidgroup

     

    aaa authentication stateful-dot1x                

       default-role "authenticated"                  

       server-group "3th_AP"                         

       enable

    Are you setting the filter-id on the RADIUS server as  "pidgroup"?

    Hi hthakker,

     

       I used Reply-message attribute on radius server not the fillter-id.

     

    anyidea?

    aakmit, 
    You should be seeing a message like the following in the user-debug logs. 

    Jun 27 07:13:41 :522017:  <INFO> |authmgr|  MAC=e8:99:c4:4e:39:53 IP=10.163.207.102 Derived role 'reply-authenticated' from server rules: server-group=radius, authentication=802.1x

     

     

    Following is my configuration 

    aaa server-group "radius"

    auth-server hthakker
    set role condition Reply-Message contains "reply123" set-value reply-authenticated

     

    Can you check if the the RADIUS server is sending out Reply-message in the Access-Accept message. 

     

    You can get packet capture on the RADIUS server and filter with "radius". 

    Attribute Value Pairs inside the Access-Accept packet 

     

    AVP: l=10  t=Reply-Message(18): reply123

    aakmit, 

     

    If you do not have the capability to get packet capture on the RADIUS server, you can check if the server is responding with the Reply message on the controller itself.

     

    (master) (config) #logging level debugging security subcat aaa
    (master) (config) #logging level debugging security process authmgr

     

    (master) # aaa test-server mschapv2 <radius-server> <username> <password>

     

    (master) #show log all | include Reply
    Jun 27 09:42:32 authmgr[1579]: <121031> <DBUG> |authmgr| |aaa| [rc_api.c:989] Reply-Message: reply123

     

     

    Also, 

    Can you post the output of the following command? 

     

    show aaa authentication wired

     

    Thanks,

    Hi hthakker,

     

    thanks for your answer. I captured packet on radius server and i saw the Reply-message return attribute list in the radius packet.

     

    radius-capture.png

     

    Then i tested with aaa test-server command i got the resault like below.

    Jun 28 06:03:37  authmgr[1565]: <121031> <DBUG> |authmgr| |aaa| [rc_api.c:989]  Reply-Message: pidgroup

     

     So, I'm pretty sure the radius return attribute correctly but i don't know while server rule doesn't apply to user.

     

    (WLAN) #show aaa authentication wired

    Wired Authentication Profile

     ----------------------------

    Parameter    Value

     ---------    -----

    AAA Profile  wire-authen

     

    (WLAN) #show aaa profile wire-authen

    AAA Profile "wire-authen"

    -------------------------

    Parameter                           Value

    ---------                           -----

    MAC Authentication Profile          N/A

    802.1X Authentication Profile       N/A

    802.1X Authentication Default Role  guest

    802.1X Authentication Server Group  N/A

    L2 Authentication Fail Through      Disabled

    RADIUS Accounting Server Group      N/A

    SIP authentication role             N/A

    Device Type Classification          Enabled

     Enforce DHCP                        Disabled

    (WLAN) #

     

    thanks in advance.

    aakmit, 

     

    Try using the following configuration instead of "stateful-dot1x" 

     

    aaa authentication-server radius "IAS"

       host "172.20.43.131"

       key xxxxxx

     

    aaa server-group "3th_AP"

     auth-server IAS

     set role condition Reply-Message contains "pidgroup" set-value pidgroup

     

     

    aaa profile "3th_AP-aaa"
    authentication-dot1x "3th_AP-dot1x_prof"
    dot1x-default-role "authenticated"
    dot1x-server-group "3th_AP"
    !

     

    aaa authentication dot1x "3th_AP-dot1x_prof"
    !

     

    Apply the "aaa profile" under the Virtual AP profile if the client is connected through an SSID of apply to the wired interface if the client traffic is coming through an untrusted wired interface 

     

     

    aaa authentication wired 

    profile "3th_AP-aaa"

    !

     

    Hope it helps !
