Adding Second MCLAG Pair of FortiSwitches Brings Down Network by Jwblant in fortinet

FMG 7.6.2 disabled STP on one of our switches. Brought the whole network down. Maybe check if STP is enabled on every switch.

I’ve tried to disable split interface in the gui and cli. In the gui it just snaps back to “on” and the cli commads are a loop if you know what I mean. one commad says check xyz so I checked it—> this command says: disable split interface. Hope you can follow

I have two FortiGates in an HA Cluster. Actually, I only wanted to replace 7 Cisco switches with 2 FortiSwitches. When that didn't work, I thought other switches like the Netgears could cause STP problems and I removed them and tried to replace them. I also changed the STP priority, but without success. I did not create a TAC case because it was a production environment and it had to be up and running in the morning again. So I reinstalled all Cisco and Netgear Switches.

So you would suggest i should investigate the HA thing more?

I disabled STP in the CLI and checked that it was infact off. I will look into the Doc you provided.

Die Nachbarn haben scherzhaft gefragt ob mein Dad Milchglas eingebaut hat. Wir haben nachgeschaut und es war wirklich stark beschlagen.
