Table 8-1. Map Styles

Hierarchical—The devices are presented in a tree- like structure, from a top-level device such as a switch, to its connecting hubs and end nodes.

Circular—The network map is displayed with devices connected in a circular pattern. Segments connect the circles.

Symmetric—The devices are spaced along an axis on the page, in a symmetrical fashion.

Orthogonal—The devices are displayed along the x and y axis. This map resembles a circuit board layout.

Cluster Size

Use the Cluster Size option to adjust the size of the clusters in your map. The options are:

■Enable Max Nodes—Check this box to select a maximum number of nodes to be displayed in a cluster. Enter the number of nodes in the Max Nodes field. If a cluster has more nodes than the specified maximum, that cluster is divided into two clusters of approximately the same size, unless the resulting cluster has fewer nodes than the specified minimum. This process continues until all clusters have fewer nodes than the maximum value, and more nodes than the minimum value.

■Enable Min Nodes—Check this box to select a minimum number of nodes to be displayed in a cluster. Enter the number of nodes in the Min Nodes field. If a cluster has fewer nodes than the specified minimum, that cluster is merged with a neighboring cluster.

■Cluster By Degree—The Degree of a node is the number of ports on the device connected to the node. A node with a degree value greater than or equal to the value entered in Cluster By Degree will become the starting node of a new cluster.
