Description: Huawei DEHA (Device Enhanced High Availability) MIB for managing enhanced high availability features including non-stop routing and stateful failover.

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-DEHA-MIB?

HUAWEI-DEHA-MIB (Device Enhanced High Availability) is a Huawei MIB covering redundancy features on modular network equipment, including non-stop routing (NSR) and stateful failover between control processors. It exposes data about a device's high-availability role, backup synchronization state, and failover/switchover history, placing it in the fault-tolerance and control-plane software status category. Monitoring it is directly about software/hardware resiliency health: confirming which control processor is currently active versus standby, whether session state is properly mirrored to the standby unit, and whether an unplanned switchover has occurred. It typically operates alongside entity/redundancy concepts similar to those in standard ENTITY-MIB-style hardware inventory, since HA roles are tied to specific physical control boards. It is deployed on modular Huawei routers and switches with dual or redundant control processors in networks where continuous forwarding during a control-plane failure is required. Engineers can download the HUAWEI-DEHA-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-DEHA-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 modular routers/switches with dual or redundant control processors

Monitoring Examples

An administrator would poll DEHA objects for the current active/standby role of each control processor and the synchronization status of NSR session state, catching a fault if the standby board falls out of sync or an unexpected switchover event appears in the failover history, either of which threatens the device's redundancy guarantee.

What Can Be Monitored

active/standby HA role
NSR/stateful failover sync status
switchover event history
control processor redundancy state

How to Use in IPNetwork Monitor

Example using hwDehaUDTPortStatisDisCellResBufOver OID:

Select a Huawei modular router or switch with dual/redundant control processor (HA failover) 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 hwDehaUDTPortStatisDisCellResBufOver 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 number of discarded cells due to receive buffer overflow. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
