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