Automatic Radio Resource Provisioning

To prevent interference between APs, the FortiOS WiFi Controller includes the Distributed Automatic Radio Resource Provisioning (DARRP) feature. Through DARRP, each FortiAP unit autonomously and periodically determines the channel that is best suited for wireless communications. FortiAP units to select their channel so that they do not interfere with each other in large-scale deployments where multiple access points have overlapping radio ranges.

To enable ARRP - GUI
  1. Go to WiFi Controller > FortiAP Profiles and edit the profile for your device.
  2. In the Radio sections (Radio 1, Radio 2, etc.), enable Radio Resource Provision.
  3. Click OK.
To enable ARRP - CLI

In this example, ARRP is enabled for both radios in the FAP321C-default profile:

config wireless-controller wtp-profile

edit FAP321C-default

config radio-1

set darrp enable

end

config radio-2

set darrp enable

end

end

Setting ARRP timing

By default, ARRP optimization occurs at a fixed interval of 1800 seconds (30 minutes). You can change this interval in the CLI. For example, to change the interval to 3600 seconds enter:

config wireless-controller timers

set darrp-optimize 3600

end

Optionally, you can schedule optimization for fixed times. This enables you to confine ARRP activity to a low-traffic period. Setting darrp-optimize to 0, makes darrp-day and darrp-time available. For example, here's how to set DARRP optimization for 3:00 am every day:

config wireless-controller timers

set darrp-optimize 0

set darrp-day sunday monday tuesday wednesday thursday friday saturday

set darrp-time 03:00

end

Both darrp-day and darrp-time can accept multiple entries.
