Description: Huawei DAD (Dual Active Detection) MIB providing objects to configure and monitor dual-active detection in stacked or clustered Huawei switch systems.
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 HUAWEI-DAD-MIB?
HUAWEI-DAD-MIB is a Huawei-proprietary MIB implementing Dual-Active Detection (DAD), a mechanism used in stacked or clustered Huawei switch/router systems to detect when a cluster has split into two independently active halves (a 'dual-active' or split-brain condition). It exposes configuration objects for DAD detection links and parameters, and status objects reporting whether a dual-active condition has been detected. Its monitoring value is critical for cluster/stack hardware and software health: detecting a split-brain event early prevents duplicate active roles, IP conflicts, and network loops that can arise from two chassis both believing they are the active master. It depends on the underlying stack/cluster management framework of the Huawei device family it runs on (e.g. CSS/iStack). It is deployed on Huawei's clustered or stacked switches and routers in high-availability core/aggregation network designs. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-DAD-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-DAD-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
- Huawei stacked/clustered switch or router
Monitoring Examples
An administrator would poll DAD detection interface/link status (patterned as an hwDadTable, though not confirmed from sample objects) and the current dual-active detection state to confirm heartbeat links between stack/cluster members are up, with a reported dual-active/split-brain state triggering an immediate failover investigation. No sample_objects were provided for this module, so specific object names are inferred rather than confirmed from source.
What Can Be Monitored
- dual-active (split-brain) detection state
- DAD heartbeat link status
- DAD configuration parameters
