Just a short note, FortiSwitch firmware version 3.6.5 just released yesterday. The release notes for the release can be found on Fortinet’s Doc website.
While there are no new features added in this firmware release, there are a few spanning-tree and MCLAG fixes that should make this the current “go to” release for switches. It does not appear that 3.6.5 has been released for the latest E series switches yet.
Slightly unrelated, when looking for the image downloads for 3.6.5, I did notice that firmware 3.6.4 has been added to the support site for the E series switches.
Happy switching!
