FortiLink over P2P Wireless Bridges

This article explains how to configure FortiLink over a point-to-point wireless bridge solution.

This has been tested using:

• 1x FG-120G (v7.6.3)

• 1x FSW-108E-FPOE (v7.4.6) - LOCAL SWITCH (assumed already in place)

• 1x FSW-224E-POE (v7.6.2) - REMOTE SWITCH (assumed factory-reset)

• 2x Ubiquiti Building Bridge (v3.1.5)

The topology appears as follows:

Instructions

1. Log in to the LOCAL SWITCH via SSH.

2. Run the following commands on the LOCAL SWITCH:

Replace the <DOWNLINK-PORT> with the port facing the LOCAL BRIDGE.

config switch physical-port
    edit "<DOWNLINK-PORT>"
        set fortilink-p2p enable
        set lldp-profile "default-auto-isl"
    next
end

Replace the <MGMT-VLAN> with the VLAN to be used for wireless bridge management.

config switch global
    set fortilink-p2p-native-vlan <MGMT-VLAN>
end

1. Log in to the REMOTE SWITCH via console cable (note: 115200-baud).

2. Run the following commands on the REMOTE SWITCH:

Replace the <UPLINK-PORT> with the port facing the REMOTE BRIDGE.

config switch physical-port
    edit "<UPLINK-PORT>"
        set fortilink-p2p enable
        set lldp-profile "default-auto-isl"
    next
end

config switch interface
    edit "internal"
        set native-vlan 4094
    next
end

Replace the <MGMT-VLAN> with the VLAN to be used for wireless bridge management.

config switch global
    set fortilink-p2p-native-vlan <MGMT-VLAN>
end

1. Connect the LOCAL BRIDGE to the nominated port on the LOCAL SWITCH

2. Connect the REMOTE BRIDGE to the nominated port on the REMOTE SWITCH

3. The two bridges should establish a link, and the FortiSwitch should appear in the FortiGate for authorisation.

If you have an on-premises UniFi Network Controller, SSH to the Wireless Bridges

• UN: ubnt

• PW: ubnt

Run command:
