Supporting SNMPv3 (Simple Network Management Protocol version 3)

SNMPv3 protocol allows for encrypted and authenticated network communications. It also lets the administrator select a desired level of security. Prior to use, at least one user name and password must be established from the settings page. To configure for SNMPv3 through the Embedded Web Server of the printer:

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 SNMP.

SNMPv3 authentication and encryption has three levels of support:

•No authentication and no encryption

•Authentication with no encryption

•Authentication and encryption

Note: Only the selected level and later may be used to communicate.

Locking the control panel menus

Control panel Menu Lockout lets you create a PIN number and choose specific menus to lock. Each time a locked menu is selected, the user will be prompted to enter the correct PIN at the control panel. The PIN does not affect any access through the EWS. To lock control panel menus:

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 Security.
