I have a setup of wireless controller C5210 v09.21.06.0006 integrated with NAC IA-A-300 for dot1.x authentication only without assessment. I installed this NAC 3 weeks ago. Till yesterday the NAC showed the AP name that the End-system connected to as well as the MAC OUI Vendor of each end-system. But today this NAC does not show any of that information. It show only the MAC address of APs along the SSID name.
Is there any advice!
Thanks in advance.
