Simple Network Management 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 between the SNMP manager and an SNMP agent 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 called trap.

SNMP Manager Overview

SNMP Manager is mounted on a Network Management Station and gathers and manages information

from SNMP agents of multiple managed network devices.

For details on SNMP Manager, see the manual of the SNMP Manager mounted on the Network

Mana

gement Station.

SNMP Agent Overview

SNMP agent is mounted on a managed network device (such as disk devices) and gathers usage and

error information, and transfers the gathered information to the SNMP manager.
