Lexmark X854e, X850e, X852e manual Disabling ports and protocols, Using 802.1x Authentication

Administrative support

Disabling ports and protocols

The TCP and UDP ports can be configured to one of three modes or values:

•Disabled—Never allows network connections to this port

•Secure and Unsecure—Allows the port to remain open, even in Secure mode

•Unsecured Only—Allows the port to only open when the MFP is not in Secure mode

Note: A password must be set to enable Secure mode. Once enabled, only the ports set to Secure and Unsecure will be open.

To configure the mode for TCP and UDP ports from the EWS:

1Open a Web browser. In the address line, enter the IP address of the MFP being configured using the format: http://ip_address/.

2Click Configuration.

3Under Other Settings, click Network/Ports.

4Click TCP/IP Port Access.

5For each port listed, select the appropriate value from the list previously described.

Note: Disabling ports will disable function on the MFP.

6Click Submit.

Using 802.1x Authentication

802.1x port authentication allows the MFP 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 MFP. The MFP 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 MFPs presenting a valid set of credentials. The credentials can be managed by using the EWS of the MFP. To use certificates as part of the credentials:

1Open a Web browser. In the address line, enter the IP address of the MFP being configured 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 EWS after installing the required certificates:

1Open a Web browser. In the address line, enter the IP address of the MFP being configured 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.

5Select the check box next to Active to enable 802.1x Authentication.
