Administrative domains are graphically represented in the tab structures as a hierarchical tree structure. In the tab tree, you can drill-down levels using menus, sub-menus, and options. The hierarchy is: Device, interface node, sub-interface node, child admin domain node, and allocated interface node.

The Domain field at the top of the tab tree represents the Root Admin Domain.
Note
The tab tree structure applies to the way the actions are performed by system users and not necessarily to any networking or physical relationship between the resources.
A user's role determines his/her view of the tab tree. Only resources the user is permitted to view are displayed in the tab tree.
