Description: Manages flash file system operations including directory listing, file transfers, and storage capacity on H3C devices.

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 A3COM-HUAWEI-FLASH-MAN-MIB?

A3COM-HUAWEI-FLASH-MAN-MIB is a joint 3Com/Huawei (H3C) enterprise MIB for managing flash storage cards and their operations on H3C networking devices. It exposes a table describing each flash device or partition present on the system, including its size, position/slot, chip count, description, initialization time, and whether it is removable or partitioned. Its monitoring value is directly hardware/storage-status oriented: administrators can check flash card presence, capacity, and initialization state to confirm the device's persistent storage (used for firmware, configuration, and logs) is healthy and has sufficient space. It is a vendor-specific module within the broader A3Com-Huawei/H3C enterprise MIB tree, typically used alongside other H3C hardware and file-system MIBs. It is deployed on H3C (Huawei-3Com) switches and routers that use removable or fixed flash storage. Engineers can download the A3COM-HUAWEI-FLASH-MAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-FLASH-MAN-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 (Huawei-3Com) switch/router

Monitoring Examples

An administrator can walk h3cFlashTable/h3cFlashEntry to see each flash card's h3cFlhSize, h3cFlhDescr, and h3cFlhRemovable status, cross-checking h3cFlhSupportNum to confirm the expected number of flash slots are populated. If h3cFlhInitTime shows an unexpectedly recent timestamp for a card that should have been installed long ago, this could indicate the flash card was reseated or reinitialized, possibly due to a hardware fault. h3cFlhPartitionBool would be checked to confirm whether a given flash card is partitioned as expected before a firmware upgrade.

What Can Be Monitored

flash card size
flash card removable status
flash card initialization time
number of supported flash slots
flash partition status

How to Use in IPNetwork Monitor

Example using h3cFlhChipWriteTimes OID:

Select an H3C/3Com switch and router 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 h3cFlhChipWriteTimes 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 a count of write times (retries) for the flash chip since initialization. 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.
