1 Overview of SNMP
Figure 1 SNMP Environment
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.
The term storage system in this guide refers to an HP StorageWorks XP12000/XP10000/SVS
200 Disk Array.
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
Management 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.
