Simple Network Management Protocol (SNMP) is a
group of internet protocols that is a de facto standard for managing
TCP/IP networks. The architectural model for SNMP contains three
components: At least one network management station
with manager software. A network management station is a host running
the network management protocol and network management applications
that manage the network. The network management applications request
information from the agents, put the information into a database,
and translate messages into a readable format. Network Agents. Network agents are managed devices
containing agent software. They may be hosts, gateway systems, or
media devices (such as bridges, hubs, or multiplexors). These agents
are responsible for performing the network management functions requested
by the network management stations. They are also responsible for
monitoring information such as the number of connections and the
speed of transmission at their location. The network management protocol (SNMP). SNMP allows
network management stations to manage (monitor and control) network devices.
SNMP is used by the stations and agents to exchange management information.
SNMP describes how agents and managers communicate and defines the
types of information that can be exchanged.
The SNMP architecture provides a framework for managing internets and
is defined in the following documents: RFC 1213 (The MIB — Management Information
Base). RFC 1155 (The SMI — Structure of Management
Information).
This chapter consists of the following major topics: Concepts and definitions. Hardware and software requirements.
