Network topology diagrams can now be enhanced with additional devices.
Why would you want to do that? Well because your network topology may contain unmanaged switches that OT-BASE cannot discover, which will regularly lead to a number of endpoints in your topology not being connected to anything.
The workflow is as follows:
Click on the new "Edit" switch after opening a network topology diagram
Anywhere on the canvas, do a right click, which will add a button "New device".
Click on this button, which will pop up the "Add Device" dialog that you already know from the device inventory.
In the dialog, enter the device details, such as make & model.
If you don't know all the details or if it's not important to record them, you could enter something like "Generic unmanaged switch". When you are done with your edits, click on "Save".
Your new device is now added to the topology.
Draw the connections to other devices in the topology using drag-and-drop.
Once that you dropped a connection to another device, a dialog will pop up that allows you to enter additional details such as port numbers. Click on "Save" when you are done with your edits.
Your manually added link is now shown as a dashed line. You may now proceed by adding additional links to other devices.
When you are done with your edits, close and re-load the topology diagram.
Your new devices and connections will be displayed according to the chosen layout option.
