Description: Huawei memory MIB providing memory utilization, pool allocation statistics, and threshold alerts for device memory resources.

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-MEMORY-MIB?

HUAWEI-MEMORY-MIB is a Huawei proprietary SNMP module that models memory resource consumption on Huawei networking equipment such as routers, switches, and access devices. It exposes device performance data in the categories of memory pool allocation, overall utilization percentage, and threshold-based alarm state. It is used directly for monitoring the software/hardware health of a device by reporting how much memory is in use relative to configured warning and critical thresholds, letting operators catch a slow memory leak or sudden exhaustion in a running process before the device becomes unstable, drops sessions, or reboots. It is typically polled alongside standard MIB-II objects and Huawei's other performance MIBs (e.g. CPU/interface utilization) to build a complete resource-health picture rather than being used in isolation. Deployment is via an NMS/EMS periodically polling Huawei carrier and enterprise routers/switches for capacity trending and automated memory-threshold alerting. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-MEMORY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-MEMORY-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 routers
Huawei switches

Monitoring Examples

No sample object names were provided for this module, so specifics beyond the module description cannot be grounded in real leaf names. In general terms, an administrator would poll the device's overall and per-pool memory utilization values on a schedule and compare them against the configured alarm thresholds. A steadily climbing utilization trend, rather than a stable sawtooth pattern, is the signature of a memory leak in a background process. Catching this early lets the operator restart the offending process or schedule a maintenance reboot before the device runs out of memory and starts dropping control-plane sessions.

What Can Be Monitored

overall memory utilization percentage
memory pool allocation/usage
free vs. used memory
memory threshold alarm status
memory usage trend over time

How to Use in IPNetwork Monitor

Example using hwMemoryDevFail OID:

Select a Huawei router or switch (memory utilization/threshold alarms) 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 hwMemoryDevFail 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 object indicates the count of memory allocation failures. 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 an Integer32-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.

OIDs

OID symbolic	OID numeric	Type	Access	Description
I32 hwBufferCurrentTotal	1.3.6.1.4.1.2011.6.3.5.2.1.3	Integer32	read-only	The object indicates the total number of the buffer currently.
I32 hwBufferCurrentUsed	1.3.6.1.4.1.2011.6.3.5.2.1.4	Integer32	read-only	The object indicates the used number of the buffer currently.
hwBufferEntry	1.3.6.1.4.1.2011.6.3.5.2.1		not-accessible	The Entries of hwBufferTable. The hwBufferTable is indexed by hwFrameIndex, hwSlotIndex, hwBufferModuleIndex and hwBufferSize. hwFrameIndex - the index of frame of the device. for example, hwFrameIndex equals 0 in NE16. hwSlotIndex - the slot number of the device, the MAX value varies with different types of devices. hwBufferModuleIndex - for the purpose of extension.In single CPU devices (NE16,eg.),hwBufferModuleIndex equals 0. hwBufferSize - the size in bytes of the buffer,such as 32 bytes,64 bytes, ...,etc.
