Figure 1 High-Level MIB Hierarchy

MIB is one of the elements of Simple Network Management Protocol (SNMP), which is used to manage network

devices. To deliver information between devices, every object referred to in an SNMP message must be listed in

the MIB. If a component of a device is not described in a MIB, that component cannot be recognized by SNMP—

there is no information for SNMP managers and SNMP agents to exchange.

The information provided by a MIB is a file that describes network elements with numerical strings. This

information is compiled into readable text by the SNMP manager. For information about reading MIB text files,

see “Reading MIB Files” on page28.

SNMP

Three significant elements of SNMP are Managers, Agents, and MIBs.

z Managers (software application) are consoles that are used to communicate with and manage devices that

support SNMP Agents. Managers collect information by polling Agents. Managers can also be used to send

configuration updates or send controlling requests to actively manage a network device.

z Agents (software application) provide information from the network devices to the Managers. Network

devices include workstations, routers, microwave radios, and other network components. Agents are

embedded in the controller firmware, unlike some devices such as servers that require the agent to be installed

separately.
