SNMP Overview
Simple Network Management Protocol (SNMP) offers the communication rules between a
management device and the managed devices on the network; it defines a series of messages,
methods and syntaxes to implement the access and management from the management device
to the managed devices. SNMP has the following characteristics:
z
Automatic network management: SNMP enables network administrators to search and
modify information, find and diagnose network problems, plan for network growth, and
obtain reports on network nodes.
z
SNMP shields physical differences between various devices and thus realizes automatic
management of products from various vendors. Offering only the basic set of functions,
SNMP makes the management tasks independent of both the physical features of the
managed devices and the underlying networking technologies. Thus, SNMP achieves
effective management of devices from different vendors, especially in small, high-speed
and low-cost network environments.
SNMP Mechanism
An SNMP-enabled network comprises a Network Management Station (NMS) and agents.
z
An NMS is a station that runs the SNMP client software. It offers a user-friendly interface,
facilitating network administrators to perform most network management tasks.
z
An agent is a program resides in the device. It receives and handles requests sent from the
NMS. Only under certain circumstances, such as interface state change, will the agent
inform the NMS.
An NMS is a manager in an SNMP enabled network, whereas agents are managed by the NMS.
The NMS and agents exchange management information through the SNMP protocol.
SNMP provides the following four basic operations:
z
Get operation: The NMS gets the value of one or more objects of the agent.
