Multicast request
The AP unit sends a multicast discovery request and the controller replies with a unicast discovery response message. The AP and the controller do not need to be in the same broadcast domain if multicast routing is properly configured.
The default multicast destination address is 224.0.1.140. It can be changed through the CLI. The address must be same on the controller and AP. For information about connecting to the FortiAP CLI, see
“Connecting to the FortiAP CLI”.
To change the multicast address on the controller
config wireless-controller global
set discovery-mc-addr 224.0.1.250
end
To change the multicast address on a FortiAP unit
cfg –a AC_DISCOVERY_MC_ADDR="224.0.1.250"
