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
