Configuration Guide Configuring SNMP
5 Configuring SNMP
5.1 Overview
Simple Network Management Protocol (SNMP) became a network management standard RFC1157 in August 1988. At
present, because many vendors support SNMP, SNMP has in fact become a network management standard and is
applicable to the environment where systems of multiple vendors are interconnected. By using SNMP, the network
administrator can implement basic functions such as information query for network nodes, network configuration, fault
locating, capacity planning, and network monitoring and management.
SNMP Versions
Currently, the following SNMP versions are supported:
SNMPv1: The first official version of SNMP, which is defined in RFC1157.
SNMPv2C: Community-based SNMPv2 management architecture, which is defined in RFC1901.
SNMPv3: SNMPv3 provides the following security features by identifying and encrypting data.
1. Ensuring that data is not tampered during transmission.
2. Ensuring that data is transmitted from legal data sources.
3. Encrypting packets and ensuring data confidentiality.
