Description: HP ICF SNMP MIB for Multi-Active Detection (MAD) in IRF stacking to detect and recover from split-brain scenarios on HP switches.

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 HP-ICF-MAD-MIB?

HP-ICF-MAD-MIB is an HP Networking (ICF, Comware-based) MIB implementing Multi-Active Detection (MAD) for IRF (Intelligent Resilient Framework) stacked switches, used to detect and recover from split-brain conditions where a stack has partitioned into multiple active fabrics. It exposes configuration and status objects related to MAD detection mechanisms (such as LACP-based, BFD-based, or dedicated MAD-link detection) and the resulting active/inactive/recovering state of stack members after a split is detected. This is a hardware/software fault-detection MIB focused on stack topology health: it lets an administrator confirm MAD is correctly configured and monitor whether a stack is currently in a healthy single-active state versus a detected split-brain condition requiring recovery action. It builds on HP's IRF stacking technology and standard detection protocols like LACP/BFD as the underlying transport for MAD probes. It is deployed on HP/H3C Comware IRF-stacked switches in campus and data-center core/aggregation layers where stack resiliency is critical. Engineers can download the HP-ICF-MAD-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HP-ICF-MAD-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

HP Networking / H3C Comware IRF-stacked switch

Monitoring Examples

Because sample_objects is empty for this entry, exact object names cannot be confirmed, but based on the module's stated purpose an administrator would poll MAD detection status objects to confirm the IRF stack has not split, and would monitor for a MAD-detected split-brain event indicating two stack members are each acting as the active fabric simultaneously, a serious condition that can cause duplicate IP/MAC conflicts on the network until MAD forces one side down for recovery.

What Can Be Monitored

MAD split-brain detection status
stack member active/inactive/recovering state
MAD detection mechanism (LACP/BFD/dedicated link) configuration

How to Use in IPNetwork Monitor

Example using hpicfMadPassthroughLacpAggPDUsRx OID:

Select an HP/H3C Comware IRF-stacked switch (Multi-Active Detection, split-brain recovery) 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 hpicfMadPassthroughLacpAggPDUsRx 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. The number of valid LACP PDUs with MAD TLV received on this aggregation port. 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.
