I am testing topology where fortigate connected to switch.

Config onFortigate.

edit "LAN" set vdom "root" set allowaccess ping set type aggregate set member "port2" "port3" set role lan set snmp-index 12 set lacp-mode static

 

Cisco Switch

 

interface Ethernet0/2 switchport trunk encapsulation dot1q switchport mode trunk channel-group 1 mode active

 

interface Ethernet0/3 switchport trunk encapsulation dot1q switchport mode trunk channel-group 1 mode active

 

interface Port-channel1 switchport switchport trunk encapsulation dot1q switchport mode trunk

 

Output on Cisco

have you tested lacp mode active ?

Even thought I set the command to active it doesnt show up so that means by default its active. which was like this when I started it and then I found in the doc to use passive. Still does work. I created another LACP with another switch and that does work so something wrong on Fortigate.

what type of cisco switch do you have?

make sure you not using a 10gig only interface on cisco if you not have a fortigate with 10gig interface. 

 

have you tested: set lacp-speed slow ?

  show lacp system-identifier
