I am collecting User-IP mapping via User-Agent quarrying the AD servers. But my wireless users authenticate via ISE and I don't see those uses in FMC. Is there a way to configure FMC to get logs from ISE (without PXGrid) or configure something on Windows Auditing to log Cisco ISE authentications?
For the ISE-authenticated users you should add ISE as an Identity source for your FMC. It does require using pxGrid.
In our case not all the devices uses ISE, like wired client do not use ISE.
I believe I am restricted to use either ISE or user-agent, is there any way audit and log authentication logs from ISE to AD audit logs.
I have not tested the results but you can configure both ISE and User Agent identity sources for a given FMC.
More details on identity sources can be found here:
