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

Under Other Settings, click

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:
1
Open a Web browser. In the address line, enter the IP address of the MFP being configured using the format: 
http://ip_address/
.
2
Click 
Configuration
.
3
Under Other Settings, click 
Network/Ports
.
4
Click 
Certificate Management
.
To enable and configure 802.1x on the EWS after installing the required certificates:
1
Open a Web browser. In the address line, enter the IP address of the MFP being configured using the format: 
http://ip_address/
.
2
Click 
Configuration
.

Under Other Settings, click

Click 
802.1x Authentication
.
Note:
If an optional internal wireless print server is installed, click 
Wireless
 instead of 802.1x 
Authentication.
5
Select the check box next to 
Active
 to enable 802.1x Authentication.
