Fortigate 201F : set up 2 port-channel (etherchannel level 2) on same Vlan
i have a fortigate 201F version 7 on NAT mode. Fortigate is between core switches and top of rack switchs. I want to use 2 LACP links to interconnect Fortigate with core (uplink LACP) and Tor switchs (downlink LACP). 2 Lacp must be trunked in order to carry many and same VLANS. 2 LACPs must be able to carry packets and communicate (switching L2 each other).
I try to set up this configuration but i meet some difficulties.
I create 2 aggregates interfaces. When i create Vlan (expect Level 2), i can't add these 2 aggregate interfaces. It just accepts one.
I try with Vlan Switch. With this type, you can't add aggregate interfaces, just physical interfaces.
So, do you know how i can achieve my network topolgy.
