Configure Agile Multiband Operation

The Wi-Fi Alliance Agile Multiband Operation (MBO) feature enables better use of Wi-Fi network resources in roaming decisions and improves overall performance. This enhancement allows the FortiGate to push the MBO configuration to managed APs, which adds the MBO information element to the beacon and probe response for 802.11ax.

config wireless-controller vap
    edit <name>
        set mbo {enable | disable}
        set gas-comeback-delay <integer>
        set gas-fragmentation-limit <integer>
        set mbo-cell-data-conn-pref {excluded | prefer-not | prefer-use}
    next
end

mbo {enable | disable}

Enable/disable Multiband Operation (default = disable).

gas-comeback-delay <integer>

GAS comeback delay in milliseconds (100 - 10000, default = 500, 0 = special).

gas-fragmentation-limit <integer>

GAS fragmentation limit (512 - 4096, default = 1024).

mbo-cell-data-conn-pref {excluded | prefer-not | prefer-use}

MBO cell data connection preference:

  • excluded: Wi-Fi Agile Multiband AP does not want the Wi-Fi Agile Multiband STA to use the cellular data connection.
  • prefer-not: Wi-Fi Agile Multiband AP prefers that the Wi-Fi Agile Multiband STA should not use cellular data connection.
  • prefer-use: Wi-Fi Agile Multiband AP prefers that the Wi-Fi Agile Multiband STA should use cellular data connection.
To configure MBO for an 802.11ax FortiAP:
  1. Configure MBO on the VAP:
    config wireless-controller vap
        edit "FOS-QA"
            set max-clients 15
            set ssid "FOS-QAehta-01"
            set pmf enable
            set pmf-assoc-comeback-timeout 8
            set mbo enable
            set gas-comeback-delay 0
            set gas-fragmentation-limit 2048
            set mbo-cell-data-conn-pref prefer-use
            set passphrase <somepassword>
            set schedule "always"
            set target-wake-time disable
            set igmp-snooping enable
            unset broadcast-suppression
            set mu-mimo disable
            set quarantine disable
            set dhcp-option82-insertion enable
            set qos-profile "test"
        next
    end
  2. Enable the VAP on a WTP profile:
    config wireless-controller wtp-profile
        edit "FAP234F-default"
            config platform
                set type 234F
                set ddscan enable
            end
            set ble-profile "new"
            set wan-port-mode wan-lan
            config lan
                set port-mode bridge-to-ssid
                set port-ssid "16sep"
            end
            set handoff-sta-thresh 55
            set ip-fragment-preventing tcp-mss-adjust icmp-unreachable
            set allowaccess https ssh snmp
            set poe-mode high
            set frequency-handoff enable
            set ap-handoff enable
            config radio-1
                set band 802.11ax
                set short-guard-interval enable
                set auto-power-level enable
                set auto-power-high 21
                set auto-power-low 1
                set darrp enable
                set vap-all manual
                set vaps "FOS-QA"
                set channel "1" "6" "11"
            end
            config radio-2
                set band 802.11ax-5G
                set short-guard-interval enable
                set auto-power-level enable
                set auto-power-low 1
                set darrp enable
                set vap-all manual
                set vaps "FOS-QA"
                set channel "36" "40" "44" "48" "149" "153" "157" "161" "165"
            end
            config radio-3
                set mode monitor
                set wids-profile "default"
            end
            config lbs
                set station-locate enable
            end
        next
    end

        set mbo-cell-data-conn-pref {excluded | prefer-not | prefer-use}
    next
end

mbo {enable | disable}

Enable/disable Multiband Operation (default = disable).

gas-comeback-delay <integer>

GAS comeback delay in milliseconds (100 - 10000, default = 500, 0 = special).

gas-fragmentation-limit <integer>

GAS fragmentation limit (512 - 4096, default = 1024).

mbo-cell-data-conn-pref {excluded | prefer-not | prefer-use}

MBO cell data connection preference:

  • excluded: Wi-Fi Agile Multiband AP does not want the Wi-Fi Agile Multiband STA to use the cellular data connection.
  • prefer-not: Wi-Fi Agile Multiband AP prefers that the Wi-Fi Agile Multiband STA should not use cellular data connection.
  • prefer-use: Wi-Fi Agile Multiband AP prefers that the Wi-Fi Agile Multiband STA should use cellular data connection.
