When users get computers from DELL, they are able to complete setup from home or company guest network. However, when the guest network is down, they would then need to get on a hot spot which is not ideal. ISE is designed / configured to allow device on production network with MAB or 802.1x, and that works perfectly for existing users/devices. What is the recommended method to allow these laptops complete initial setup when they are at the office and when the guest network is down?
