Description: Manages device module inventory, slot states, and hardware component events on H3C Layer 2 switch platforms.

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 HH3C-LswDEVM-MIB?

HH3C-LswDEVM-MIB is a vendor-specific SNMP module from H3C (Hewlett-Packard/Huawei-affiliated networking vendor, now HPE-owned) for managing device module inventory, slot states, and hardware component events on H3C Layer 2 switch platforms. It exposes CPU utilization tables, memory usage tables, and flash/device module inventory objects, covering the physical and modular composition of the switch. This is fundamentally a hardware/software health monitoring MIB: hh3cCpuCostRatePer1Min/hh3cCpuCostRatePer5Min track CPU load over time, hh3cMemSize/hh3cMemFree/hh3cMemRawSliceUsed track memory utilization, and the device/flash objects support tracking hardware slot and module presence - all classic indicators used to detect an overloaded, memory-starved, or partially failed switch. It likely complements standard entity/interface MIBs (such as ENTITY-MIB) for physical inventory, though this is not explicitly stated in the source. Typical deployment context is enterprise or campus network closets running H3C/HPE Comware-based Layer 2 switches, and administrators can download the HH3C-LswDEVM-MIB file to load into their monitoring tools.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-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

  • H3C Layer 2 managed switch

Monitoring Examples

An administrator would poll hh3cCpuTable/hh3cCpuEntry per hh3cCpuIndex to read hh3cCpuCostRatePer5Min, flagging sustained high CPU load that could indicate a control-plane issue or attack. Walking hh3cMemTable by hh3cMemModuleIndex to compare hh3cMemFree against hh3cMemSize reveals memory pressure on a specific module before it triggers a crash or packet drops. A sudden drop in hh3cMemFree alongside rising hh3cCpuCostRatePer1Min would be a strong signal of a runaway process or memory leak on the switch.

What Can Be Monitored

  • CPU utilization (1-min/5-min)
  • memory total/free/used
  • device module inventory
  • flash storage status

How to Use in IPNetwork Monitor

Example using hh3cCpuCostRate OID:

Select an H3C Layer 2 managed switch (CPU/memory/module inventory) 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 hh3cCpuCostRate 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.
