9.9 SNMP
Simple Network Management Protocol (SNMP) is a protocol for managing networks and
devices in the network. To transmit data, SNMP uses the connectionless "UDP" protocol.
Information about the properties of SNMP-enabled devices is stored in Management
Information Base (MIB) files.
You can find basic information on this topic in the "Diagnostics and configuration with SNMP"
manual on the Web pages of the Siemens Industry Online Support
( https://support.industry.siemens.com/cs/ww/en/view/103949062 ).
