Chapter 9 Manage Administrator Accounts of Omada SDN Controller 9. 1 Introduction to User Accounts Omada SDN Controller offers three levels of access available for users: master administrator, administrator, and viewer. Because the controller can be accessed both locally and via cloud access, users can be further grouped into local users and cloud users. Multi-level administrative account presents a hierarchy of permissions for different levels of access to the controller as required. This approach ensures security and gives convenience for management. ■■ Master Administrator There is only one master administrator who has access to all features. The account who first launches the controller will be the master administrator and cannot be changed and deleted. ■■ Administrator Administrators can create and delete viewers in the Admin page, but they can be created and deleted only by master administrator. In the Settings page, administrators have no permission to some modules, including cloud access, migration, auto-backup, etc. ■■ Viewer Viewers can only view the status and settings of the network, and they cannot change the settings. The entrance to Admin page is hidden for viewers, and they can be created or deleted by the master administrator and administrator. 322
