This chapter explains how to configure the SNMP settings on the VMG.

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.

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.
