6. SNMP Agent
6.1. General
Simple Network Management Protocol (SNMP, see RFC1157 standard) is used in network management systems
to monitor network-attached devices for conditions that warrant administrative attention. A management agent
is installed in the managing station, and exchanges data via get and set requests.
6.2. Community Strings
SNMP uses community strings for authentication. SNMP support and default community strings are required for
PROFINET comformance. For security reasons it is strongly recommended to change the values of these strings.
See attributes #20 and #21 in the
6.3. Management Information (MIB)
A MIB is a device database that is accessed by an SNMP agent. The Anybus CompactCom 40 PROFINET IRT
supports standardized MIBs: LLDP-MIB and MIB-II. Standardized MIBs are defined in RFC standards and contain
variables that are divided into so called groups. The host application can change the values of some of the
variables for the MIB-II.
6.4. MIB-II
The MIB-II of the Anybus CompactCom 40 PROFINET IRT contains the system- and interfaces group. The following
tables show the variables according to the MIB-II standard (RFC1213) for monitoring the device status. The
access authorizations refer to access via the SNMP protocol.
