Device Groups and Interface Groups are the primary organizational units in NetMRI. You can create device groups in a nested structure, with some device groups subordinate to other device groups. You can apply device group membership criteria in the same ways with nested device groups as for device groups from earlier releases of NetMRI, which used a flat data structure and enforced all device groups as existing on the same peer level. You can now create a hierarchical list of device groups, comprised of top-level groups, with child device groups subordinate to them, and with child device groups further subordinate to their parent groups. For more information, see Creating Device Groups.
NetMRI uses device groups to organize device discovery results, generate separate scorecards, filter issues, and manage polling and processing for each device in the network. Device groups also offer control of Switch Port Management processes, including the ability to immediately carry out Switch Port polling in a device group.
