Basic Dial NMS Implementation Guide
Overview of Basic SNMP Building Blocks
About SNMP
The Simple Network Management Protocol (SNMP) is an application-layer protocol that facilitates the
exchange of management information between a network management system (NMS), agents, and
managed devices. SNMP uses the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol
suite.
There are three versions of SNMP:
SNMP Version 1 (SNMPv1)
—The initial implementation of the SNMP protocol, which is
described in RFC 1157 (http://www.ietf.org/rfc/rfc1157).
SNMP Version 2 (SNMPv2)
—An improved version of SNMPv1 that includes additional protocol
operations. For the SNMPv2 Structure of Management Information (SMI), see RFC 1902
(http://www.ietf.org/rfc/rfc1902).
SNMP Version 3 (SNMPv3)
—SNMPv3 has yet to be standardized.
The case study in this guide describes how to create a dial NMS environment. To successfully manage
the environment, you must be familiar with the SNMP feature set. The following NMS applications use
SNMP to help manage the network devices in the case study:
UCD-SNMP
Multi-Router Traffic Grapher (MRTG)
HP OpenView (HPOV)
