SNMP. Simple Network Management Protocol
The SNMP protocol permits central network management for many network components. The primary objectives of
SNMP are a decrease in the complexity of the management functions, the expandability of the protocol and
independence from any network components.
There are three areas of management in which this protocol can be used:
During monitoring, events can be recorded and data for network statistics collected. Controlling supports
the modification of device parameters and device variables. During administration, information is recorded
which describe the development of the network configuration.
The architectural model of SNMP is very simple. According to this model, a network is divided into network management stations (NMSs) and network components.
The network management stations execute applications for monitoring and controlling the network components.
The network components router, host, bridge and terminal server have management agents which perform the
management functions. The management station and the network components communicate by means of SNMP.
This communication includes the transfer of relevant management data collected by the network components.
