Security Fabric Topology
You can see the Security Fabric topology in the FortiManager GUI, in the Fabric View menu. You can choose the Physical Topology or Logical Topology views. In both topology views, you can hover over device icons and use filtering and sorting options to see more information about devices and your organization's network. Go to Fabric View and select the Fabric group to see the whole topology for that Fabric group.
WAN Cloud Icon
The WAN cloud icon, in the Physical and Logical Topology views, allows you to receive destination data from the following options in the drop-down menu: Internet, owner IP address, and country/region. These options are available in the Physical Topology and the Logical Topology view, when you select Device Traffic in the menu in the top right corner.
When you set the WAN cloud icon to Owner, the destination hosts are simplified to a fixed size donut chart. This chart shows the percentage division between Internal hosts (with private IP addresses) and Internet hosts. To see which color represents each host, hover over either color. To zoom in on the total number of hosts, click on the donut graph.
FortiAP and FortiSwitch links are enhanced in the Security Fabric’s Logical and Topological views to show Link Aggregation Groups for the Inter-switch Link (ISL-LAG). This makes it easier to identify which links are physical links and which links are ISL-LAG. To quickly understand connectivity when you look at multiple link connections, ISL-LAG is identified with a thicker single line. To identify ISL-LAG groups with more than two links, you can also look at the port endpoint circles as references.
