APC Domains

Expand the domain to view the spans in the domain. You can view the APC information for a node side by right-clicking a span and choosing the node side from the shortcut menu. The information appears in the right pane of the APC tab. See the node-name side {A | B | C | D | E | F | G | H} area described later in this table.
