Configuring the Discovery Interface

By default FortiBranchSASE models have different ports designated as the discovery interface. These interfaces are used to establish connectivity with FortiGate or FortiSASE for device discovery and onboarding.

Model	Discovery interfaces
FBS-20G / FBS-20G WiFi	Port 1 and Port 2
FBS-10F WiFi	WAN port

To configure the discovery interface on a FortiBranchSASE device - CLI:

config system management
  set discovery-type auto
  config fortigate
    set ac-discovery-type broadcast
    set ac-ctl-port 5246
    set ac-data-port 25246
    set discovery-intf port1 port2
    set ingress-intf 
  end
end
