The configuration examples in this chapter assume that iMaster NCE-Campus V300R020C10 only provides authentication functions but does not manage devices, and switches run V200R020C00 or later versions. The GUIs and operation procedures may vary according to the version of iMaster NCE-Campus. Perform operations based on the actual version used on the live network. For details about how iMaster NCE-Campus manages devices, see CloudCampus Solution.
