What Is Wellfleet-HWF-MIB?
Wellfleet-HWF-MIB is a legacy Wellfleet Communications (later Bay Networks/Nortel, built on Wellfleet-COMMON-MIB) proprietary MIB reporting Hardware Filter (HWF) driver records — only one HWF driver may be spawned per slot, so slot number alone indexes the table. Its objects cover delete/enable flags, state, slot, available-lines count, and a per-line table (state, slot, line number, circuit, capable/current max table size, current used entries, dropped-frames count). As a status/performance MIB it lets an administrator confirm hardware-filter capacity and watch dropped-frame counts per line on a legacy Wellfleet (Bay Networks/Nortel) router. It is deployed on legacy Wellfleet Communications (Bay Networks/Nortel) routers (hardware filter). Engineers can download the Wellfleet-HWF-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Wellfleet-HWF-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.
What Can Be Monitored
- hardware-filter table capacity and dropped-frame counts
Supported Devices
- Legacy Wellfleet Communications (Bay Networks/Nortel) routers (hardware filter)
Monitoring Examples
An administrator checks wfHwfLineDroppedFrames and wfHwfLineCurrentUsedEntries to confirm hardware-filter capacity and frame drops on a legacy Wellfleet (Bay Networks/Nortel) router line.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| wfHwfTable | 1.3.6.1.4.1.18.3.4.6.1 | not-accessible | The following table will contain information about a collection of Hardware Filter (HWF) driver records. Only one HWF driver may be spawned, by the loader, on a given slot. Hence, only the slot number is used as the instance identifier into the table. | |
| wfHwfEntry | 1.3.6.1.4.1.18.3.4.6.1.1 | not-accessible | Slot number used as instance identifier. | |
| INT wfHwfDelete | 1.3.6.1.4.1.18.3.4.6.1.1.1 | INTEGER | read-write | Create/delete parameter. |
| INT wfHwfEnable | 1.3.6.1.4.1.18.3.4.6.1.1.2 | INTEGER | read-write | Enable/disable parameter. |
| INT wfHwfState | 1.3.6.1.4.1.18.3.4.6.1.1.3 | INTEGER | read-only | Driver state variable. |
| INT wfHwfSlot | 1.3.6.1.4.1.18.3.4.6.1.1.4 | INTEGER | read-only | Slot number -- instance ID. |
| INT wfHwfAvailableLines | 1.3.6.1.4.1.18.3.4.6.1.1.5 | INTEGER | read-only | Number of available lines on module. |
| wfHwfLineTable | 1.3.6.1.4.1.18.3.4.6.2 | not-accessible | The following table will contain information about a collection of Hardware Filter (HWF) line records. | |
| wfHwfLineEntry | 1.3.6.1.4.1.18.3.4.6.2.1 | not-accessible | Slot number and line number used as instance identifier. | |
| INT wfHwfLineState | 1.3.6.1.4.1.18.3.4.6.2.1.1 | INTEGER | read-only | State of filtering hardware on a per line basis. |
| INT wfHwfLineSlot | 1.3.6.1.4.1.18.3.4.6.2.1.2 | INTEGER | read-only | Slot number -- instance ID. |
| INT wfHwfLineNumber | 1.3.6.1.4.1.18.3.4.6.2.1.3 | INTEGER | read-only | Line number -- instance ID. |
| INT wfHwfLineCct | 1.3.6.1.4.1.18.3.4.6.2.1.4 | INTEGER | read-only | Circuit number associated with a line. |
| INT wfHwfLineCapableMaxTblSize | 1.3.6.1.4.1.18.3.4.6.2.1.5 | INTEGER | read-only | This attribute specifies the maximum number of table entries capable of being used by a line based upon actual hardware filter devices present and available. |
| INT wfHwfLineCurrentTblSize | 1.3.6.1.4.1.18.3.4.6.2.1.6 | INTEGER | read-only | Current capacity of the hardware filter table. Hardware filter table resources are dynamically allocated (in increments of 256) on an as-needed basis up to the available table size. |
| INT wfHwfLineCurrentUsedEntries | 1.3.6.1.4.1.18.3.4.6.2.1.7 | INTEGER | read-only | Number of hardware filter table entries used. |
| INT wfHwfLineDroppedFrames | 1.3.6.1.4.1.18.3.4.6.2.1.8 | INTEGER | read-only | Number of frames dropped because of hardware filter match. |
