Description: Huawei LAN switch device management MIB providing hardware inventory, board status, and device health monitoring for Huawei stackable 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 HUAWEI-LswDEVM-MIB?

HUAWEI-LswDEVM-MIB is Huawei's LAN switch device management MIB, providing hardware inventory, board status, and core device health monitoring for Huawei stackable LAN switches. It exposes CPU utilization tables with per-minute and per-5-minute cost-rate averages, memory tables reporting total size, free memory, and raw slice usage, alongside general device (hwDevice), memory (hwMem), and flash (hwFlh) management branches. This is a core hardware-health MIB: it is explicitly used to monitor CPU load trends and memory exhaustion/fragmentation on switch hardware, both classic early-warning indicators of an overloaded or failing device before it becomes unresponsive. It is a Huawei-private module, though it parallels concepts found in the standard ENTITY-MIB and HOST-RESOURCES-MIB for hardware/resource monitoring. It is deployed on Huawei stackable LAN switches in enterprise and campus networks as a standard target for NMS CPU/memory health dashboards, forming the basis of HUAWEI-LswDEVM-MIB SNMP monitoring for CPU and memory trends.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-LswDEVM-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 stackable LAN switches

Monitoring Examples

An NMS would poll hwCpuCostRatePer1Min and hwCpuCostRatePer5Min from hwCpuTable per hwCpuIndex to track CPU load trends on a switch, flagging sustained high 5-minute averages as a sign of control-plane overload. It would also poll hwMemFree from hwMemTable per hwMemModuleIndex against hwMemSize to compute free-memory percentage, and watch hwMemRawSliceUsed for memory fragmentation. A steadily declining hwMemFree trend with rising hwCpuCostRate values would indicate an impending resource-exhaustion event, prompting a proactive switch reboot or process investigation before the device becomes unmanageable.

What Can Be Monitored

CPU utilization (1-min, 5-min averages)
total and free memory per module
memory raw slice usage
flash/storage status

How to Use in IPNetwork Monitor

Example using hwCpuCostRate OID:

Select a Huawei stackable LAN switch (CPU/memory hardware health) 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 hwCpuCostRate 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 overall CPU busy percentage in the last 5 second period. 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 Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if utilization exceeds 85%, a common warning threshold before sustained high load affects performance. Click Finish to create the monitor; you can adjust any parameter later.
