ISE BYOD: Dual vs. Single SSID Onboarding,
•
In general it is recommended to minimize number of ‘ SSIDs. Also, if the guest access is using hotspot access then single-SSID BYOD is recommended as the open SSID using hotspot portal cannot be used for initial BYOD portal at the same time. With Single-SSID BYOD, the endpoint associates to […]
