How are Host Names of Devices Decided?

You can set the hostname of the device to whatever you would like. This will allow them to all have individual hostnames and be able to be quickly recognized at a glance. config system global set hostname " desired name" end There' s a lot of different ways you could name them. Make it something that defines the device and lets you know what it is.

Hi Paul, I' ve ran into the same issue at a customer network the other day. The MAC addresses were showing up correctly, but all the hostnames were from a wifi controller device in the network. Unfortunately the admin guide doesn' t have much information on this (http://docs.fortinet.com/uploaded/files/1946/fortigate-managing-devices-52.pdf). Would love it if someone has some details on how the hostname is derived exactly. From memory (on a general theme) the FortiGates look at the DHCP VCI (Vendor Class Identifier) if it can see DHCP traffic. It also looks at the TCP SYN packets and the HTTP UserAgent packets to determine some of its info.
