SNMP
SNMP (Simple Network Management Protocol)
SNMP is a protocol for managing networks. To transmit data, SNMP uses the connectionless
UDP protocol.
The information on the properties of SNMPcompliant devices is entered in MIB files (MIB =
Management Information Base).
The CP supports data queries using SNMP in version 1. It delivers the content of certain MIB
objects according to the MIB II standard, LLDP MIB, Automation System MIB and
MRP Monitoring MIB.
The CP continues to support data queries via SNMPv3 (security enabled).

The CP supports the following groups of MIB objects of the standard MIB II according to
RFC1213:
• System
• Interfaces
• IP
