# Setting IEEE802.1X Authentication

Specify the settings for using IEEE802.1X authentication with the printer.
See the following sections according to the protocol to be used for authentication.
"Setting TLS Authentication Information"
"Setting TTLS/PEAP Authentication Information"

IMPORTANT
###### Conditions for Using IEEE802.1X Authentication In order to use IEEE802.1X authentication, an authentication server (RADIUS server) is required.

NOTE
###### IEEE802.1X Authentication Protocol The printer supports TLS, TTLS and PEAP IEEE802.1X authentication. TLS performs mutual authentication using the certificate sent from the authentication server and the certificate set in the printer. TTLS and PEAP perform mutual authentication using the certificate sent from the authentication server and the user name and password set in the printer. Note the following when simultaneously specifying multiple options from TLS, TTLS, and PEAP: To select TLS: TTLS or PEAP cannot be specified. To select TTLS: TLS cannot be specified. PEAP can be specified. To select PEAP: TLS cannot be specified. TTLS can be specified. The network authentication method to use is determined by the configuration of the authentication server in use. Choose the method based on the configuration of the authentication server. ###### IEEE802.1X Authentication Settings We recommend that network settings be performed by the network administrator.
