Forti Cluster with LACP connect CISCO SVI Switch

Hi Kindly advise we have a requirement to configure as below,

Forti Member1 > Switch 1

Forti Member1 > Switch 2

Forti Member2 > Switch 1

Forti Member2 > Switch 2

According to the physical connection, we have 4 connections to the Cisco Switch SVI environment.

Cisco side we need to correct one port channel, can someone advise if is it possible to do this? do i need to modify the connection configuration?

Thank you,

Duminda.

Hello,

I suppose that the two Cisco switches are in a single cluster and allow to aggregate those 4 ports (2 port of each switch ) on a single LAG using LACP.
If yes you can treat them as a single switch and refer to this article: https://community.fortinet.com/t5/FortiGate/Technical-Tip-LACP-behavior-in-an-HA-cluster/ta-p/195163
or the configuration guide: https://docs.fortinet.com/document/fortigate/6.0.0/handbook/207052/ha-with-802-3ad-aggregate-interfaces
