MIBs Provided with TCP/IP Services

This chapter describes how MIBs are implemented on OpenVMS. The MIBs provided with TCP/IP Services are:

The Host Resources MIB, which manages operating system objects (Section 2.1)

MIB II, which manages TCP/IP kernel objects (Section 2.2)

2.1Overview of the Host Resources MIB

The Host Resources MIB defines a uniform set of objects useful for the management of host computers. The Host Resources MIB, described by RFC 1514, defines objects that are common across many computer system architectures. The TCP/IP Services implementation of SNMP includes many of these defined objects. In addition, some objects in MIB II provide host management functionality.

2.1.1 Defining Host Resources MIB Implemented Objects

This section defines each of the implemented eSNMP objects. Table 2–1 provides a general RFC description and a specific OpenVMS description for each implemented object.
