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:
â–  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.
â–  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.
â–  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.
â–  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.
SNMP Operations
SNMP itself is a simple request/response protocol. NMSs can send multiple requests without receiving a
response.
