31.1 Overview
This chapter explains how to configure the SNMP settings on the VMG.
31.2 The SNMP Screen
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your VMG supports SNMP agent functionality, which allows a manager
station to manage and monitor the VMG through the network. The VMG supports SNMP version one
(SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation.
Figure 146 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 VMG). 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.
