Simple N etwork Man agem ent Protocol ( SNMP) is an industry-standard the protocol for managing and
monitoring network devices, including disk devices, routers, and hubs. SNMP uses Simple Gateway
Management Protocol (SGMP) to manage the TCP/IP gateways.
The standardized configuration and database of network management information is called a
Management Information Base (MIB) . A standard MIB is common to all SNMP interfaces. An extension
MIB
is defined by the particular managed device or protocol.
An SNMP manager monitors the devices, which are referred to as managed nodes. The primary types of
interaction bet ween the SNMP manager and an SNMP ag ent are polling and trap.Typically, the SNMP
manager polls the SNMP agents on a periodic basis, to determine whether the device is operating
normally. If an abnormal event occurs, the SNMP Agent can report the condition without a request from
the
manager, by using a message c alle d trap.
