Challenge with Cisco ISE (Identity Service Engine) Integration for user-id mapping

[risi76]

Hello All,

I am currently trying to integrate the cisco ise (radius server) to the Palo Alto Syslog filters so that the users that be tagged and policy applied to different categories of guest based on ISE permission.

Currently ISE seem to be sending authentication logs to Palo Alto but cannot seem to build the right regex to pull the relevant information.

Has anyone been able to do this?

Appreciate the response.

Best Regards

dan

Hello Dan,

It looks like, previously you have  posted a similar query on this discussion forum, but still that is not answered. ( Cisco ISE Regex). In this situation, I would request you to consult with your Palo Alto SE for more relevant information.

Thanks

I must have forgotten, thanks for the reminder.

Best Regards
