SNMP Management

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information
between network devices. The IES-1000 supports SNMP versions one and two (SNMPv1 and SNMPv2) agent
functionality, which allows a manager station to manage and monitor it through the network.
The next figure illustrates an SNMP management operation.

Figure 16-1 SNMP Management Model

An SNMP managed network consists of two main component types: agents and a manager.
An agent is a management software module that resides in a managed device (the IES-1000). An agent translates
the local management information from the managed device into a form compatible with SNMP. The manager is
the station through which network administrators perform network management functions. It executes operations
that control and monitor the managed devices.
The managed devices contain objects that define each piece of information to be collected about a device.
Examples of variables include the number of packets received, node port status, etc. A Management Information
