In contrast to Static Groups, Dynamic Groups do not let you select individual equipment. You simply configure a filter, and Open Manage Network Manager creates the group on the fly. After you enter the Name and Category for the group, create the filter. To see what the group would look like, click Preview Group. This opens the Preview tab, concealing the General tab. To return to General, click that at the top of the screen. Click Save to preserve the group configuration, or Cancel to exit without saving.
