https://community.extremenetworks.com/t5/extremecontrol/visualize-device-in-nac/m-p/91136#M271 Hi Johan,<BR /><BR />As far as I know, DHCP requests are a way to "gather" devices information, but in order the device to appear in the NAC Control, you have to configure your current switches with -at least- RADIUS MAC Authentication on the your wired access ports (and in the EAC you create an "always allow" rule, that reply with "access-accept" messages to your switch), this will help you having the visibility. Pay attention to set a "Fail-safe" policy on your switches so that in case of EAC engine failure, your wired access can keep on working.<BR /><BR />Regards, Mon, 14 Mar 2022 18:28:38 GMT LaurentA 2022-03-14T18:28:38Z https://community.extremenetworks.com/t5/extremecontrol/visualize-device-in-nac/m-p/91134#M269 I have a network, non extreme.<BR /><BR />The DHCP request are send to&nbsp; EAC engine.<BR /><BR />Can those device been displayed by NAC Controle?
