SNMP And its Working

Simple Network Management Protocol
Use Simple Network Management Protocol (SNMP) management software to monitor any network device configured with SNMP agent software. The SNMP agent, which is an optional component of Windows Server 2003, interacts with third-party SNMP management software to enable the flow of network status information between monitored devices and applications and the management systems that monitor them.
You can use SNMP in environments that include large networks with hundreds or thousands of nodes that would otherwise be difficult and costly to monitor. SNMP allows monitoring of network devices such as servers, workstations, printers, routers, bridges, and hubs, as well as services such as Dynamic Host Configuration Protocol (DHCP) or Windows Internet Name Service (WINS).

SNMP Architecture

To perform its monitoring services, SNMP uses a distributed architecture of management systems and agents and several related components. Windows Server 2003 provides an SNMP agent that is designed to be capable of interacting with any SNMP manager. The following components are the building blocks of SNMP and the Windows Server 2003 SNMP agent:
  • SNMP management systems and agents
  • Management Information Base (MIB)
  • SNMP Messages
  • SNMP Communities
  • The communication process between SNMP managers and agents 
The internal architecture of the Windows Server 2003 implementation of SNMP is divided into management and agent functions, which, in some cases, overlap. The following figure illustrates how the Windows Server 2003 SNMP structure fits into the layers of the underlying TCP/IP protocol architecture.
