My friends, I have two switches 424E and two 148F. The SWs are with version 6.4.6. My Fortigate VM is version 6.4.4. My topology is very simple! The two 424E receive the same fortilink (a STACK) and each with a 148F. But this is not working! I turned off the "split interface" as recommended. Only one side is working( 424E + 148F). Is there a problem or configuration on VMWARE (vswith for example) !? If I use two Fortilinks (two STACKs), I see two working! I need to have all switches on the same STACK. Thanks in advanced, Marcio - HXBRASIL

Marcio,

You'll have to set up MC-LAG between the 424E's using an ICL (inter-chassis link) then connect the 148Fs via ISL to each 424E. Only after you set up the MC-LAG would you disable split interface on the FortiLink. Have you gone through the multi-chassis LAG setup?

Thanks

Thanks for the answer! But which topology should I use? a) Two FORTLINKS interfaces or b) A FORTILINK interface

Thank you again!

You're going to have ONE FortiLink interface with two interfaces in it. You will just add multiple interfaces in the FortiLink interface setup:

edit "FortiLink"

set vdom "root"

set fortilink enable

set ip 192.168.121.1 255.255.255.0

set allowaccess ping fabric

set type aggregate

set member "port23" "port24"

set description "FortiLink"

set lldp-reception enable

set lldp-transmission enable

set snmp-index 9

set auto-auth-extension-device enable

set lacp-mode static
