SNMP configuration

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

shields the physical differences between various devices and realizes automatic management of

products from different manufacturers.

An SNMP enabled network comprises the network management system (NMS) and agents.

The NMS manages agents by exchanging management information through SNMP. The NMS and

managed agents must use the same SNMP version.

Currently, SNMP agents support SNMPv1, SNMPv2c, and SNMPv3.

• SNMPv1 uses community name for authentication. Community name defines the relationship

between an SNMP NMS and an SNMP agent. SNMP packets with community names that do not

pass the authentication on the device are simply discarded. A community name plays a similar role

as a key word and can be used to control access from NMS to the agent.

• SNMPv2c uses community name for authentication. Compatible with SNMPv1, it extends the

functions of SNMPv1. SNMPv2c provides more operation modes such as GetBulk and

InformRequest; it supports more data types such as Counter64; and it provides various error codes,

thus being able to distinguish errors in more detail.

• SNMPv3 offers an authentication that is implemented with a User-Based Security Model (USM).

You can set the authentication and privacy functions. The former is used to authenticate the validity

of the sending end of the authentication packets, preventing access of illegal users; the latter is used

to encrypt packets between the NMS and agents, preventing the packets from being intercepted.

USM ensures a more secure communication between SNMP NMS and SNMP agent by

authentication with privacy.
