Select Topology to view the switch topology. The Topology page shows an overview of FortiSwitch islands connected to FortiSwitch Cloud.
A FortiSwitch island contains a cluster of connected FortiSwitch units, as well as devices that are not managed by FortiSwitch Cloud. Depending on whether FortiSwitch Cloud can obtain valid root information from Spanning Tree Protocol (STP), each FortiSwitch island is displayed with either an LLDP-based graph or an LLDP-and-STP-based graph with tiers. The host name is displayed for FortiSwitch units; MAC addresses are displayed for non-FortiSwitch devices.
To update the topology display, select Refresh.
To display networks with inter-switch links (ISLs), select On for Show Inter-Switch-Link Network.
By default, only topologies containing more than one FortiSwitch unit are displayed. To display single FortiSwitch topologies, select Off for Hide Single Switches.
To find a specific FortiSwitch unit, enter the host name in the Search field, and the node for the switch is highlighted. If you select a node in the Topology pane and then go to the Detail Topology view, the node is still highlighted to make it easier to locate it.
To filter the FortiSwitch units by tag, select and the tag to filter with. If you select multiple tags to filter with, the results are FortiSwitch units that are tagged with one or more of the selected tags.
To examine the details of the topology of one of the FortiSwitch islands, select , and the Detail Topology view is displayed.
In the Detail Topology view, you can do the following:
- When the cursor changes from a crosshair to an arrow, you can click and drag the graph to where you want it.
- To look at a subset of connected nodes, use your cursor to click and drag around the nodes that you want to examine. When you release the cursor, only the selected nodes are displayed. You can repeat this action until a single node remains. Select Reset to see the entire graph.
- To look at a subset of nodes that are not connected, select On for Multiple Brushes, use your cursor to click and drag around the nodes that you want to examine, and then select Apply Brush. Select Clear Brush to undo your selections before selecting Apply Brush again.
- You can zoom in and out by using the scroll wheel on your mouse.
- To collapse the topology, select the icon.
- To expand the topology, select the icon.
- To see the connections between ports, select a node.
NOTE: Ports that are not connected are not displayed. You cannot zoom in on ports with a brush.
- In an LLDP-based graph (a topology without tiers), you can click on a node and drag it to make the host names easier to read.
- To change the Detail Topology view to the default settings, select Reset.
- To display networks with inter-switch links (ISLs), select On for Show Inter-Switch-Link Network.
- To display the state of ports for a single Spanning Tree Protocol (STP) instance, select On for Show STP Topology. When you hover over a link, a tooltip displays the detailed state of the connected ports.
- To change which STP instance is displayed, select the instance number from the STP Instance drop-down list.
- To return to the Topology pane, select Close.
