Aggregating multiple LAN ports

Certain FortiAP models including FAP-320C, FAP-421E, and FAP-U421EV, have two ports, labeled LAN1 and LAN2. These ports can be re-configured to function as one aggregated link, per IEEE 802.3ad Link Aggregation Control Protocol (LACP), allowing data traffic across both ports to increase the overall throughput and support redundancy.

Note: You can only enable the Link Aggregation Control Protocol (LACP) from the FortiAP CLI. The commands for enabling LACP differ depending on the FortiAP model type.

To enable LACP on a FortiAP, FortiAP-S, or FortiAP-W2 model - CLI

1. Access the CLI of your FortiAP (see FortiAP CLI access).

2. In the FortiAP CLI, set the WANLAN_MODE parameter to AGGREGATE by entering the following command:

   cfg -a WANLAN_MODE=AGGREGATE

   Note: By default, WANLAN_MODE is set to WAN-ONLY.

3. Save the changes to the device flash with the following command:

   cfg -c

To enable LACP on a FortiAP U model - CLI

1. Access the CLI of your FortiAP (see FortiAP CLI access).

2. In the FortiAP CLI, set the FAP_ETHER_TRUNK parameter to 2 by entering the following command:

   cfg -a FAP_ETHER_TRUNK=2

   Note: By default, FAP_ETHER_TRUNK is set to 0.

3. Save the changes to the device flash with the following command:

   cfg -c
