By default, expanding a node marked with a plus sign adds all nodes that are one hop away from the node. For example, expanding a BGP service node shows all the BGP session objects and peer BGP service objects associated with the BGP service node.
You can use any of the following methods to expand a node marked with a plus sign:
Select the node and then select Expand Map Element from the Map Console Map menu.
Right-click the node and then select Expand Map Element.
Select the node and click the Show neighboring nodes button.Note:
Double-clicking a node launches either a Notification Properties dialog box or a Topology Browser view for the object, depending on whether any notifications are associated with the object.
