I have the following scenario, Fortigate towards FortiSwitch 2048F in MCLAG, and access switches connected to both 2048F. I was able to configure MCLAG, and add 2 access switches without issue. Meaning GUI topology on managed fortiswitch is showing what is expected.
But as soon as I add the 3rd access switch, the topology changes and one of my MCLAG interface went missing on the GUI as well as the MCLAG grouping.
I am using 7.4.8 on FortiGate, 7.6.2 on FortiSwitch. I am only using the GUI on FortiGate to create all of this.
I also tried using 7.6.3 on FortiGate and 7.6.2 on FortiSwitch and the GUI topology is much worst, It shows Fortilink connection as dotted line as well as the MCLAG connection.
Let me check!
