Chapter 3. Working with SNMP printers SNMP support Currently, InfoPrint Manager supports Simple Network Management Protocol (SNMP) V1. However, companies are shipping printers with SNMP V3. If you configure your printer to use SNMP Version 3, you need to turn off the InfoPrint Manager SNMP support by specifying False for the use-snmp actual destination attribute. Note: 1. If you configure your printer to use SNMP V3 and turn on the InfoPrint Manager SNMP support, it could impact the overall performance of the InfoPrint Manager SNMP support. 2. If you specified the destination-tcpip-internet-address actual destination attribute, the use-snmp actual destination attribute is set to True by default. About SNMP communication For network printers that work with Simple Network Management Protocol (SNMP) and the standard printer management information block (MIB) RFC 1759, the InfoPrint Manager server can use SNMP to automatically: v Set the default of several InfoPrint Manager actual destination attributes in the printer to the values returned in the standard printer MIB. The actual destination attributes pertain to trays, media, bins, plexes, and sides. This process is called smart-defaulting the attributes. v Detect, report, and recover from printer problems for several conditions, even if no jobs are currently being printed. v Assess device specific information directly. v Execute device commands directly on the device. With PTF UO00979 , InfoPrint Manager adds support for SNMP Version 3 (SNMPv3). This version enhances the security of SNMP communications between InfoPrint Manager and printers, and it includes encrypted and authenticated management traffic and protected remote configuration and device status messages. SNMPv3 supports three levels of security: v Minimum- Without authentication and privacy. v Medium- With authentication, but without privacy. v Maximum- With authentication and privacy. To support these three security levels, new SNMPv3 actual destination attributes are added. See "Procedures" on page 40 for more information. Smart-defaulting actual destination attributes The InfoPrint Manager server can automatically smart-default an actual destination attribute for an SNMP printer only if an InfoPrint Manager user does one of these: © Copyright InfoPrint Solutions Company 1998, 2010 35
