FortiGate manage FortiSwitch by FortiLink over Layer3 Core Switch (Non-FortiSwitch)
I'm trying to set up a network environment where a FortiGate centrally manages a FortiSwitch. In the existing environment, all endpoint devices are assigned to different VLANs (such as 101, 201, 301, etc.), and all endpoint device IP gateways are configured on the core switch.
After successfully creating the FortiLink over a Layer 3 network to manage the FortiSwitch—following the reference link and documentation—I am able to manage and assign VLANs to the FortiSwitch from the FortiGate. However, I found that user traffic and DHCP assignment are also failing on the FortiSwitch. It seems the FortiSwitch cannot receive or forward any Layer 2 or Layer 3 traffic to the core switch.
Please advise if there is any misconfiguration or if you have any suggestions. Thank you very much!
Current Network Environment/HLD:
Internal Firewall (FortiGate) <-> Layer3 Core Switch (Cisco, H3C, Juniper, etc) <-> Access Switch (FortiSwitch) <-> User/Endpoint Devices
