Simple Network Management Protocol (SNMP)
4.3.1
General function
SNMP is a manufacturer-neutral standard for Ethernet management. It defines commands
for reading and writing information, and defines formats for error and status messages.
SNMP is also a structured model that comprises agents, their relevant Management
Information Base (MIB) and a manager. The manager is a software tool, which is executed
on a network management station. The agents are located inside switches, bus terminal
modules, routers, and other devices that support SNMP. The task of the agents is to collect
and provide data in the MIB. The manager regularly requests and displays this information.
The devices can be configured by writing data from the manager to the MIB. In the event of
an emergency, the agents can also send messages (traps) directly to the manager.

All configuration modifications, which are to take effect after an FL NAT SMN 8TX(-M)
