Hello again,

I found this solution. Can you tell me if it helps, please?

To set up redundancy paths between FortiSwitches using both fiber and WiFi bridges with FortiAPs in a mesh configuration, ensure that FortiLink P2P is properly configured and that no traffic is blocked on the Layer 2 setup. Consider using MCLAG or STP for redundancy, and review the specific configuration settings for FortiLink and P2P-FortiLink to ensure compatibility.

Hello again plsikk and sorry for the delay!

I found this solution to your question. Does it help? :)

To configure FortiLink over a point-to-point layer-2 network, especially when using a WiFi bridge, follow these steps:

1. Enable FortiLink P2P on Each FortiSwitch Unit:
   - Access the configuration for the physical port on each FortiSwitch unit that connects to the WiFi bridge.
   - Use the following commands: ```shell config switch physical-port edit <port_name> set fortilink-p2p enable end ```
   
   
2. Ensure Consistent TPID Values:
   - Make sure the FortiLink point-to-point TPID value is the same on each FortiSwitch unit. By default, it is 0x8100.
   - Use the following commands to verify or set the TPID: ```shell config switch global set fortilink-p2p-tpid <0x0001-0xfffe> end ```
   
   
3. Check Layer-2 Network Configuration: Ensure that the WiFi bridge and any intermediate Layer-2 devices are not blocking LLDP packets or any other necessary traffic for FortiLink.
   
   
4. Review Redundancy Protocols: If redundancy is required, consider using protocols like MCLAG or STP to manage the failover between the fiber and WiFi bridge links.
   
   
5. Troubleshoot Connectivity: If switches go offline when connecting the fiber port, check for any loops or misconfigurations in the network that might cause a broadcast storm or other issues.

By following these steps, you should be able to configure FortiLink over a WiFi bridge and troubleshoot any issues with the setup. If problems persist, further network analysis may be required to identify specific issues.
