SNMP implementation
MIB files
Your meter is compliant with MIB-II as defined by the standard MIB file RFC 1213.
SNMP requires that you load your meter’s ION MIB file (available for download from
www.usa.siemens.com/pds) into the NMS.
You must install RFC 1213, which is required to read basic network information for the
meter (for example, TCP/IP traffic or number of packets received), if it is not included
with your SNMP manager software.
