Chapter 1. Introduction

SNMP OVERVIEW

The term SNMP broadly refers to the message protocols used to
exchange information between the network and the managed
devices, as well as to the structure of network management data
bases. SNMP has three basic components:

Network Manager

Control program that collects, controls, and presents data pertinent
to the operation of the network devices. It resides on a network
management station.

Agent

Control program that resides in each network device connected.
This program responds to queries and commands from the
network manager and returns requested information or invokes
configuration changes initiated by the manager.

MIB

Index to the organized data within a network device. It defines the
operation parameters that can be controlled or monitored.
The DSU IV supports the MIB-II standard, RFC 1213, and
ADTRAN Enterprise Specific MIB. MIB files are available from
ADTRAN in the support section of the ADTRAN webpage at
www.adtran.com.
The DSU IV's embedded SNMP feature allows the unit to be
accessed and controlled by a network manager through either a
device running SLIP or async PPP protocol (connected to the
CONTROL port of the DSU) or through a LAN. A LAN connection
requires the optional ESP ethernet card (P/N 1204005L1). This card
provides a 10BaseT ethernet interface to the LAN.
