Simple Network Management Protocol (SNMP)
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
permits network administrators to manage network performance, find and solve network
problems, and plan for network growth.
An SNMP-managed network consists of the following:
• 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.
