Model 5399 Remote Access Concentrator Network Administrator’s Guide for UNIX

Book A

Chapter 2

Simple Network Management

Protocol (SNMP)

T

his chapter describes the Simple Network Management Protocol

(SNMP) and the SNMP agent provided by the 5399 RAC. This chapter
includes the following sections:

•

SNMP Protocol Overview

•

Setting up the 5399 RAC for SNMP

•

Standard MIB Support

•

Parameters vs. Private Enterprise MIB

•

5399 RAC Modem and Call Statistics.

SNMP Protocol Overview

SNMP is a heavily used management protocol. It operates over the User
Datagram Protocol (UDP), which is part of the TCP/IP protocol suite.
SNMP provides an easier and more efficient means of managing the 5399
RAC.

•

The SNMP network management station or application can send
queries to the SNMP agents located in each 5399 RAC.

•

Each SNMP agent collects information about its 5399 RAC and
provides that information to the Network Management Station.
The agent process acts as a server in a typical client-server
model.

•

Management Information Bases (MIBs) located on the SNMP
Network Management Station describe the information that
comes from the agents.
