Chapter 11 The IBM 6400 Printer Management Model
150
Agent/Manager Model
The elements of a monitoring system, MIB and SNMP, are implemented
in an agent/manager model:
• The manager is a console, workstation, or server on working hubs or
routers which has a global knowledge of NICs and printers.
• Agents are utilities that reside on devices, such as a NIC, that
respond through SNMP to management requests for information. The
information is stored in a MIB (Management Information Base).
MIB
A MIB is a management information base that contains information a
device makes available to SNMP. The MIB describes information about
actual objects to be managed and controlled. There are many different
MIBs defined.
Standards of IBM Network Printer MIBs
The Printer MIB is based on the following standards:
• System and Interfaces Group MIB (RFC 1213 of March 1991)
• Host Resource MIB (RFC 1514 of September 1993)
• Printer MIB (RFC 1759 of March 1995)
Components of the Printer MIB
The IBM Printer MIB gives the network manager access to most of the
information that is normally accessible through the NIC command set for
configuring the server with SNMP. Some objects identified by this MIB are
not applicable to the NIC.
The complete definition of the Printer MIB is provided in the Printer MIBs
in DOS Format and Printer MIBs in TAR Format, which are shipped with
the NIC. The MIB is provided in a subset of the ASN.1 syntax. The Printer
MIB is composed of the following sections:
• General
• Cover
