Description: Hirschmann HiOS (HM2) network objects MIB defining reusable address and service object groups for policy rules.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is HM2-NETOBJ-MIB?

HM2-NETOBJ-MIB is a Hirschmann HiOS (HM2 platform) MIB that defines reusable network object groups, such as address and service definitions, used as building blocks for firewall/ACL or policy rules on Hirschmann industrial Ethernet switches. It exposes a table of named network objects along with per-object data entries and their associated data table, effectively representing named collections of addresses or values referenced elsewhere in the device's policy configuration. Its monitoring value is primarily configuration-state visibility rather than runtime performance: an administrator can confirm how many net objects and data entries are defined (hm2NetobjectsCount, hm2NetobjectsDataEntriesCount) and inspect each object's name and row status to verify that security/policy object definitions are present and active as expected. It is a self-contained Hirschmann proprietary MIB, though it complements SNMPv2 RowStatus conventions and Hirschmann's broader HiOS policy/ACL MIBs. It is typically deployed on Hirschmann industrial switches used in automation and critical-infrastructure networks where address/service objects underpin firewall or access control policies. Engineers can download the HM2-NETOBJ-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HM2-NETOBJ-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Hirschmann HiOS industrial Ethernet switch

Monitoring Examples

An administrator would poll hm2NetobjectsTable entries by hm2NetobjectsIndex to read hm2NetobjectsName and hm2NetobjectsRowStatus, confirming that a named network object used in an ACL rule is correctly defined and active (rowStatus = active). Cross-checking hm2NetobjectsDataTable entries via hm2NetobjectsDataTableObjIndex reveals whether the expected data values (addresses/services) are actually populated under that object. An object showing notInService or notReady row status, or an unexpectedly empty hm2NetobjectsDataTable, would reveal a misconfigured or incomplete policy object definition.

How to Use in IPNetwork Monitor

Example using hm2NetobjectsCount OID:

Select a Hirschmann HiOS industrial Ethernet switch (named network object groups) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hm2NetobjectsCount into the Find box to locate it in the OID tree, then select it and click OK. The current number of netobject entries in the netobjects table. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
