DLC/LLC Using the checkbox provided, you can enable (check) or disable (clear) the DLC/LLC (Data Link Control/ Logical Link Control) protocols on the HP Jetdirect print server. If the checkbox is clear, DLC/LLC protocols are disabled. NOTE: HP Jetdirect 635n print servers: except for TCP/IP, network protocols are disabled by factory default. SNMP You can specify or change the SNMP (Simple Network Management Protocol) parameters provided. See Table 4-11 SNMP Tab Settings on page 76. CAUTION: If you use HP Web Jetadmin to manage your devices, you should use HP Web Jetadmin to seamlessly configure SNMP v3 and other security settings on the print server. Using the embedded Web server to create the SNMP v3 account will erase any existing SNMP v3 accounts. In addition, the SNMP v3 account information will need to be implemented on the SNMP management application. For more information, see SNMP v3 on page 92. Table 4-11 SNMP Tab Settings Item Description Enable SNMPv1/v2 readwrite access This option enables the SNMP v1/v2c agents on the print server. Custom community names can be configured to control management access to the print server. An SNMP Set Community Name is a password to be able to configure (or "write") SNMP information on the HP Jetdirect print server. An SNMP Get Community Name is a password to retrieve (or "read") SNMP information on the HP Jetdirect print server. An incoming SNMP SetRequest or GetRequest command must contain the appropriate Set or Get community name before the print server will respond. A community name must be ASCII characters and can be up to 255 characters long. To restrict access, the default Get community name "public" can be disabled by checking the checkbox provided. NOTE: If "public" is disabled, some port monitors or discovery utilities may not operate properly.

The default Get community name "public" is automatically enabled. This option disables the SNMP v1/v2c agents on the print server, which is recommended for secure environments. If SNMP v1/v2c is disabled, some port monitors or discovery utilities may not operate properly. (Full-featured HP Jetdirect print servers only) This option enables (check) or disables (clear) the SNMP v3 agent on the print server. When enabled, an SNMP v3 account must be created on the print server, and the account information must be implemented on the SNMP v3 management application. You may create an account by providing the following information: User Name: the SNMP v3 account user name. 76 Chapter 4 Embedded Web Server (V.36.xx) ENWW
