Using 802.1x Authenticating

802.1x port authentication allows the printer to join networks that require authentication before allowing access. 802.1x port authentication can be used with the WPA (Wi-Fi Protected Access) feature of an optional internal wireless print server to provide WPA-Enterprise security support.

Support for 802.1x requires the establishment of credentials for the printer. The printer must be known to the Authentication Server (AS). The AS will allow network access to devices presenting a valid set of credentials which typically involves a name/password combination and possibly a certificate. The AS will allow network access to printers presenting a valid set of credentials. You can manage the credentials by using the Embedded Web Server of the printer. To use certificates as part of the credentials:

1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the format: http://ip_address/.

2Click Configuration.

3Under Other Settings, click Network/Ports.

4Click Certificate Management.

To enable and configure 802.1x on the Embedded Web Server after installing the required certificates:

1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the format: http://ip_address/.

2Click Configuration.

3Under Other Settings, click Network/Ports.

4Click 802.1x Authentication.

Note: If an optional internal wireless print server is installed, click Wireless instead of 802.1x Authentication.
