The simple network management protocol (SNMP) use for 
monitoring of network-attached devices for any conditions 
that warrant administrative attention. It is use to manage 
IP network devices such as servers, routers, switches etc. 
Administrator can find or manage network performance, solve 
problem or even optimize it further. It works at TCP/IP 
Application layer 5 (L5

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).
