I've deployed wireless OOB NAC. Some user can login normally, but some other user can not login. The error message is OOB Error: connected device <client_MAC> not found. This only happen at some PC user.
When some wireless user cannot login, i usually issue command clear mac address-table dynamic on the switches then the problem is solved temporarily. I wonder why this was happened. Is there any parameter that i need to tune in NAC or WLC or switches?
