37.3 SNMP
Simple Network Management Protocol is a protocol used for exchanging
management information between network devices. SNMP is a member of TCP/IP
protocol suite. A manager station can manage and monitor the IES-1248-51V
through the network via SNMP version one (SNMPv1) and/or SNMP version 2c.
The next figure illustrates an SNMP management operation. SNMP is only available
if TCP/IP is configured.
Figure 124 SNMP Management Model
An SNMP managed network consists of two main components: agents and a
manager.
An agent is a management software module that resides in a managed device (the
IES-1248-51V). 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.
