You're missing

  set member "port1" "port2"

under "Outside".

HI Toshi_Esumi,

 

I have deleted the ports sorry, traffic on primary fortigate is working, but on secondary firewall the port connected to cisco switch are suspended

It might be something to do with virtual MAC address on each vlan, and probably nothing to do with LAG setting. I don't have any a-a HA so I don't know how it would work. But below old KB says if only one side (your case outside only) is connected to the same switch, it should be fine.
If no one else replies, I would recommend you open a TAC case to ask.

Then please share the answer. I want to know as well.
