SNMP Overview

SNMP (Simple Network Management Protocol) is used by network management systems to manage and
monitor network-attached devices. SNMP is based on the manager/agent model consisting of a manager,
an agent, a database of management information, managed objects, and the network protocol. The manag-
er provides the interface between the human network manager and the management system. The agent
provides the interface between the manager and the physical devices being managed (Figure 40). SNMP
uses basic messages (such as GET, GET-NEXT, SET, and TRAP) to communicate between the manager
and the agent.

6.7.3.3.1.1 MIB
The manager and agent use a Management Information Base (MIB), a logical, hierarchically organized
database of network management information. MIB comprises a complete collection of objects used to
manage entities in a network. A long numeric tag or object identifier (OID) is used to distinguish each
variable uniquely in the MIB and SNMP messages.
