Description: Hirschmann HiOS (HM2) Layer 2 redundancy MIB for RSTP, MSTP, and ring redundancy protocol configuration.
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-L2REDUNDANCY-MIB?
HM2-L2REDUNDANCY-MIB is a vendor-specific MIB from Hirschmann, part of the HiOS management model ('HM2'), for industrial Ethernet switches, covering Layer 2 redundancy protocols such as the Media Redundancy Protocol (MRP) ring alongside RSTP/MSTP. It exposes ring redundancy configuration and operational state, including MRP domain identity, the two ring ports (each with its interface index, group ID, and operational state), and the node's redundancy role in both admin and operational form. It is directly used to monitor the fault-tolerance health of the network topology: the operational state of each ring port reveals whether that link is up, and a mismatch between the configured and operational redundancy role can indicate a role-negotiation failure, both critical to catch before a ring break causes a network outage. It complements standard RSTP/MSTP objects from the IEEE 802.1 bridge MIBs, since HiOS devices support MRP alongside those spanning-tree protocols. It is typically deployed on Hirschmann industrial Ethernet switches used in ring topologies for factory automation, process control, and other industrial network environments requiring fast failover. Engineers can download the HM2-L2REDUNDANCY-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HM2-L2REDUNDANCY-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 admin would poll hm2MrpTable, indexed by hm2MrpDomainID, to check hm2MrpRingport1OperState and hm2MrpRingport2OperState for each ring; if one ring port shows a down/faulted state while the other stays up, that indicates a ring break, though the network keeps functioning via the redundant path. Checking hm2MrpRoleOperState against hm2MrpRoleAdminState confirms whether the configured redundancy manager/client role actually took effect, catching a stuck failover after a device reboot. hm2MrpDomainName correlates the ring's logical name to the specific physical port pairs identified by hm2MrpRingport1IfIndex/hm2MrpRingport2IfIndex during troubleshooting.
What Can Be Monitored
- MRP ring port 1/2 operational state
- MRP ring port interface index and group ID
- redundancy role (admin vs. operational)
- MRP domain identity/name

How to Use in IPNetwork Monitor
Example using hm2MrpMRMRingOpenCount OID:
Select a Hirschmann HiOS industrial Ethernet switch (MRP ring/RSTP redundancy) 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 hm2MrpMRMRingOpenCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the counter will be incremented when the ring state changes to ring open. 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 a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
