SNMP Configuration
12.1
Introduction
Simple Network Management Protocol offers a frame structure for low level network
management. The SNMP is widely used to control various network devices. SNMP basic
functions include network performance monitoring, network error checking and analysis
and network device configuration. SNMP can be used to gather statistics, configuration
and testing for a network and also error detection and recovery functions.
An SNMP managed network consists of three key components: a managed device, an
agent (the software which runs on the managed device) and the Network Management
System (NMS) this is the software which runs on the manager. SNMP itself does not
define which information a managed system should offer, it uses available information
defined by Management Information Bases (MIBs). The MIBs describe the structure of
the management data of a device subsystem, they use a hierarchical namespace
containing Object Identifiers (OIDs) and each OID identifies a variable that can be read
or set via SNMP.
In SNMPv2, authentication of clients is performed by a community string which is a type
of password transmitted in clear text. A Trap is a function for the Agent issuing a
message to NMS instead of a response to a request to report emergency alarms. There
can be five Trap server stations.
