Q 1. Could you let me know the Reports which shows web/dot1x auth user name and his ip address.
(Now I am thinking Radius Accounting Report. Please let me know this is not the right one.)
Yes, the RADIUS Accounting Report shows this
Q2. I would like to schedule the Q1 report. Is it possible to take it as .csv file?
Absolutely. At the top right of the Report Page, there is a button marked Schedule. Click this
Choose your schedule frequency and repository (Make sure you have your FTP Set up as a Repository), and this will be sent as a .csv file.
