SNMP Configuration 
SNMP Overview 
The Simple Network Management Protocol (SNMP) is an application layer protocol 
that facilitates the exchange of management information between network devices. 
It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. 
SNMP enables network administrators to manage network performance, find and 
solve network problems, and plan for network growth.

An SNMP-managed network consists of four key components: Network management 
stations (NMSs), SNMP agents, Management information base (MIB) and network-
management protocol: 
•  Network management stations (NMSs):  Sometimes called consoles, these 
devices execute management applications that monitor and control network 
elements. Physically, NMSs are usually engineering workstation-caliber computers 
with fast CPUs, megapixel color displays, substantial memory, and abundant disk 
space. At least one NMS must be present in each managed environment. 
•  SNMP Agents:  Agents are software modules that reside in network elements. 
They collect and store management information such as the number of error 
packets received by a network element.
