SNMP
24.1 Overview
This chapter explains how to configure the SNMP settings on the PMG2006-T20A.
24.2 The SNMP Screen
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your PMG2006-T20A supports SNMP agent functionality, which allows a
manager station to manage and monitor the PMG2006-T20A through the Network Management System
(NMS). The PMG2006-T20A supports SNMP version one (SNMPv1) and version two (SNMPv2c). The next
figure illustrates an SNMP management operation.

SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the PMG2006-T20A).
An agent translates the local management information from the managed device into a form
compatible with SNMP. The manager is the console through which network administrators perform
network management functions. It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of packets
received, node port status etc. A Management Information Base (MIB) is a collection of managed
objects. SNMP allows a manager and agents to communicate for the purpose of accessing these
objects.
