This chapter describes configuring Simple Network Management Protocol
(SNMP), the network management protocol that governs the exchange
between nodes and stations.
About SNMP and the Digi Device Agent
This section introduces SNMP and network management in TCP/IP
networks and it describes the device server agent. It discusses the
following:
Network management components

Network Management Components
The TCP/IP network management architecture contains the following
components:
Managed nodes such as host systems, routers, terminal and
communications servers (such as device server) and other network
devices.
One or more network managers (also called network management
stations), which are the points from which the network is managed
Agents that reside on managed nodes and retrieve management
information and communicate this information to network managers.
The network management protocol, SNMP, which governs the
exchange of information between the nodes and stations.
Management information, which is the database of information about
managed objects. This database is called the management information
base (MIB).
SNMP Management Agent
Each managed node contains at least one agent—a component that
responds to requests from the network manager—that retrieves network
management information from its node and notifies the manager when
significant events occur.
