On FortiGate, automatic BSS coloring is enabled by default, when a collision is detected on FortiAP radio, it changes the color. It is also possible to change the mode from automatic to static. In Both modes, collision detection works.
BSS Color configuration in FortiOS :
# config wireless-controller wtp-profile
Example : AUTO.
Example : STATIC.
BSS Color config verification in FortiAP CLI :
FortiAP-231F # rcfg . .
bss color mode : static /auto
FortiOS CLI :
FGT# diagnose wireless-controller wlac -c wtp FP231FTF20004934 | grep bss
Note: once set BSS coloring mode to static and set value to 0, which means BSS coloring is disabled. BSS coloring status can be checked under iwpriv command:
BSS coloring disabled:
FortiAP-231F # iwpriv wifi0 g_he_bss_color wifi0 g_he_bss_color:256 (0x100)
BSS coloring enabled:
FortiAP-431F # iwpriv wifi1 g_he_bss_color wifi1 g_he_bss_color:21 (0x15)
