Within each group category (polling groups, threshold groups, device access groups, and IP tagging filter groups), groups can be arranged in a high-to-low priority. A managed object is compared against the highest priority group first and becomes a member of the first group for which there is a criteria match.
A managed object may become a member of different groups in different group categories, but a managed object may only be a member of one group within a particular group category.
The IP Manager User Guide provides information on working with groups and settings and the IP Manager Reference Guide provides information on Polling settings, Threshold settings, default polling groups, their target classes, matching criteria and their default settings.
