Configuration Guide Configuring SNMP
 SNMP Network Manager
The SNMP network manager is a system that controls and monitors the network based on SNMP and is also called the NMS.
 SNMP Agent
The SNMP agent (hereinafter referred to as the agent) is software running on the managed devices. It is responsible for
receiving, processing, and responding to monitoring and control packets from the NMS. The agent may also actively send
messages to the NMS.
 MIB
The MIB is a virtual network management information base. The managed network devices contain lots of information. To
uniquely identify a specific management unit among SNMP packets, the MIB adopts the tree hierarchical structure. Nodes in
the tree indicate specific management units. A string of digits may be used to uniquely identify a management unit system
among network devices. The MIB is a collection of unit identifiers of network devices.
