ISE Wired guest portal redirect even after authentication

pemasirid

Level 1

Hi

I have configured both Wired and Wireless guest authentication via guest portal. Wireless is working fine, however the when trying with Wired, the redireciton page is keep getting even after user authenticated.

I'm not seen the redirection authorization policy in my logs however I can see only the user authentication logs (successful). Attached is my configuration and logging output.

Here is what I see on the interface

ABQT-3FLR-ACC-01#sh authentication sessions interface gigabitEthernet 4/0/19

            Interface:  GigabitEthernet4/0/19

          MAC Address:  a0b3.ccca.2ab1

            User-Name:  A0-B3-CC-CA-2A-B1

               Status:  Authz Success

               Domain:  DATA

       Oper host mode:  multi-auth

     Oper control dir:  both

Here is the ACL

Can you please tell us what is your switch model, also the configratoin on the interface ...

Thanks

Sorry, I missed to write the swtich/software details.. here it is:

WS-C2960S-48FPD-L  IOS version: 15.0(2)SE1

Try to

remove the last policy "Guest Wired Redirect"

change "Wired MAB" policy to be :

"NetworkAccess:UseCase=Hostlookup" and "Session:Posture Status=Unknown" conditions

without Wired_MAB condition

Remove the first two policices and add new one at the top "GUEST" policy:

GUEST if Network Access:UseCase EQUALS Guest Flow then PermitAccess

let me know if this works

Hi Mohannad,

I tried with the above changes, but now it seems it does not hit those policies as I see I'm getting default Deny Access authorization policy. Then I enabled previosuly created Wired_MAB and got the login portal and after giving the username/passwords it again redirecting the same login portal.

Attached is my Authorization policy and logging screen shots. We need to the reason for "Dynamic Authentication Failed" error we see after username/password accepted.

Screen shots are attached as stated.

Regards,

The changes should work. Can you past the interface configration of the switch, please make sure the MAB is enabled.

Also, make sure in the authentication in the ISE continue if the user was not found as shown in the bellow figure

Hi Mohannad,

Thanks for your response.

Actually the as per the configuration it should work, I'm still trying to find out what is what has gone wrong with this configuration. Infact I have tested with 3560 switch with the same config and it worked. only difference here is we used 2960S switch.

We need to find out why the next Auth policy is not hitting once user is authenticated.

Here is the port configuration and the authen status of the port.

Hi Mohannad,

I found the issue and fixed it and its working perfectly now.

The issue was on radius dynamic-author key, so I re-configured the key and started working

aaa server radius dynamic-author

client X.X.X.X server-key xxxxx

thanks a lot for all your responses.
