The unit supports Simple Network Management Protocol (SNMP) Versions 1, 2c & 3.
Creating SNMP MIB fi les
There are two Westermo MIBs.
One is generated on the unit after the firmware has been installed. This is done using the “mibprint”
CLI command and the “MIBEXE” DOS tool which is available from the Technical Support team. This
MIB changes with every firmware release as the firmware revision is embedded in the OIDs. This
MIB provides access to most configuration and statistics.
The second is the “Westermo Monitor MIB” which is a standard MIB that gives access to various
Westermo proprietary objects. The OIDs in this MIB do NOT change with each release although it
is possible for new objects to be added to it. This MIB is available from the Technical Support team.
The standard MIBs supported are:
SNMP MIB (RFC3418)
Interfaces MIB (RFC2233)*
IP MIB (RFC2011)
IP Forwarding Table MIB (RFC2096)
TCP MIB (RFC2012)
