Network topology maps contain objects that may include IP networks, VLANs, routers, switches, hosts, and various types of connections such as cables and trunk cables. In a map display, a node is a graphical representation of a topology object, and an edge is a graphical representation of a relationship or connection between objects.
Note that your system administrator may replace the standard map icons with other map icons that are preferred by your organization. In that case, use Map > Map Legend to see the definitions of your map icons.
