Description: Hirschmann HiOS (HM2) management access MIB for controlling SNMP, SSH, and HTTPS access to the device.

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-MGMTACCESS-MIB?

This MIB module is part of Hirschmann's HiOS (HM2) enterprise MIB tree and governs management access to Hirschmann industrial Ethernet switches, controlling which protocols and ports can be used to reach the device for configuration. It exposes configuration-oriented data: administrative enable/disable status for SNMPv1/v2/v3, SNMP-over-802 (Ethernet), the SNMP trap service, and web management via HTTP and HTTPS, along with the TCP port numbers those services listen on. Rather than physical hardware telemetry, this MIB is mainly used to monitor the software/service status of the device's management plane — whether SNMP, web, or trap services are enabled, which ports they use, and whether an HTTPS certificate is present, which is essential for security-compliance monitoring. It has no heavy external MIB dependency beyond the vendor's own HM2 enterprise tree, though it interacts conceptually with standard SNMP framework MIBs. It is typically deployed in industrial/rugged network environments (factory automation, rail, energy) where Hirschmann switches are common, letting admins verify management-access hardening settings across many switches. Engineers can download the HM2-MGMTACCESS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HM2-MGMTACCESS-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 industrial Ethernet switch (HiOS/HM2 platform)

Monitoring Examples

An administrator polling hm2SnmpV3AdminStatus, hm2WebHttpsAdminStatus, and hm2WebHttpsCertPresent across a fleet of Hirschmann switches can detect devices where SNMPv1 is still enabled (a security risk) or where HTTPS is enabled but no certificate is installed. Checking hm2SnmpPortNumber and hm2WebHttpsPortNumber against expected values flags devices where a technician changed management ports from defaults, which could break existing monitoring scripts. hm2SnmpTrapServiceAdminStatus confirms whether trap forwarding is active before troubleshooting missing alerts.

What Can Be Monitored

  • SNMPv1/v2/v3 admin status
  • SNMP trap service status
  • SNMP over 802 status
  • HTTP/HTTPS web management status
  • management port numbers
  • HTTPS certificate presence

How to Use in IPNetwork Monitor

Example using hm2WebHttpsCertPresent OID:

Select a Hirschmann industrial Ethernet switch 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 hm2WebHttpsCertPresent into the Find box to locate it in the OID tree, then select it and click OK. Indicates what HTTP certificate files are present on the device, if any. 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 INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'pem', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.
