Automatic BSS coloring 7.0.2
BSS coloring is a mechanism in 802.11ax that enables spatial reuse when overlapping BSS occurs. This can happen when adjacent APs use the same channels and, in the case of BSS coloring, the same color. Automatic Basic Service Set (BSS) coloring can be configured in the FortiGate wireless controller for the FortiAP radios to automatically change colors when BSS coloring conflicts are detected. Automatic BSS coloring is enable by default.
config wireless-controller wtp-profile edit <profile> config <radio> set bss-color-mode {auto | static} end next end
The following configurations show the WTP profiles for a FortiAP U431F that has three radios. The two examples demonstrate using automatic and static BSS coloring to separate the BSS color on the two radios to prevent coloring conflicts.
To configure the FortiAP profile with automatic BSS coloring:
config wireless-controller wtp-profile edit "FAPU431F-BSS-auto" config platform set type U431F end set handoff-sta-thresh 30 set allowaccess https ssh config radio-1 set band 802.11ax-5G set vap-all manual end config radio-2 set band 802.11ax,n,g-only set vap-all manual end config radio-3 set mode monitor end next end
# diagnose wireless-controller wlac -c wtp PU431F5E19000105 | grep "bss color" bss color mode : Auto bss color mode : Auto
To configure the FortiAP profile with static BSS coloring:
config wireless-controller wtp-profile edit "FAPU431F-BSS-static" config platform set type U431F end set handoff-sta-thresh 30 set allowaccess https ssh snmp config radio-1 set band 802.11ax-5G set bss-color 60 set bss-color-mode static set vap-all manual end config radio-2 set band 802.11ax,n,g-only set bss-color 50 set bss-color-mode static set vap-all manual end config radio-3 set mode monitor end next end
# diagnose wireless-controller wlac -c wtp PU431F5E19000105 | grep "bss color" bss color mode : Static bss color : 60 bss color mode : Static bss color : 50
