We currently have a pair of Fortinet 1500D the have the internal port(s) connected to a C3 stack. I would like to take it off the stack and connect it to the SSA-T1068 at the top of the network for our central office. Last night I attempted to do so while upgrading some other switches. Let's say I was not very successful. Has anyone else encountered problems with Fortinet/Extreme interoperability? I am new to Extreme and any assistance would be very helpful.
Are you sure the ports came up on the right speed/duplex? On Fortinet stuff, I have had to manually set speed and duplex once, but that was on a Fortigate 1000A.
