4.3 Simple Network Management Protocol

4.3.1 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 three 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.

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.

Management information base (MIB)

A MIB is a collection of managed objects residing in a virtual information store.

Collections of related managed objects are defined in specific MIB modules.

Network-management protocol

A management protocol is used to convey management information between agents and

NMSs. SNMP is the Internet community's de facto standard management protocol.
