Unfortunately, Aruba does not have autodiscovery tools to add nodes automatically. As your network grows and the number of devices monitored by Aruba increases, you have to maintain a device directory as you would with any other directory. Keep in mind, however, that modifications to your directory won't be recognized by Aruba. After I entered the IP addresses of the devices, Aruba was able to get detailed information about each. Devices in Aruba can be classified in groups arranged in a tree hierarchy.
Any single device can be a part of multiple groups.
I created groups by locations and by organizations. I established several and defined their top-level groups. A user can access all the components in the tree hierarchy below the top-level group. The level assigned affects which reports a user can view. For example, assigning a specific level in the hierarchy to your user would let him or her create groupings from that point in the tree, and assign other users and rights below that branch.
