Topology map layout
The Management application provides several layouts for the IP Topology, Ethernet Fabrics, L2
Topology, and VLAN Topology views, so that you can determine which one provides the best display
of your network topology. When selecting a layout, keep the following in mind:
• When you first open a Topology view, the Topology Map uses the layout option specified in the
Topology Display dialog box. In a typical topology, the default layout for all topology views is
Organic. For IP Topology, the default layout is Circular. For VLAN topologies, the default layout is
Orthogonal (Merge Lines).
• The position of nodes on the next layout type depends on their position in the previously
displayed layout. You may see a better display if you choose the Circular layout first, then
choose the next layout you want to try.
• As you move from one layout to another the Management application animates the process of
redrawing the map.
When a topology map update is in progress, you can interact with client. The layout
management is a background thread. The amount of computing resource required to draw a
new layout depends on the number of nodes and connections on the network. If the layout
execution duration exceeds a minimum threshold, a progress bar displays. The minimum
threshold duration is 1 second.
• During a session, as you enter and exit any of the topology views, the last layout used is the
one displayed when you return to that topology view. However, the layouts are reset to the
default layouts when you logout of the Management application.
The following examples show the differences between the layouts. They may or may not match the
map drawn for your network. Also, some of the examples may look alike; however, the layouts may
look different on networks with more devices.
