What Is DLB-ATHDRV-STATS-MIB?
DLB-ATHDRV-STATS-MIB is a private MIB from Deliberant, a manufacturer of point-to-point/point-to-multipoint wireless bridges built on Atheros wireless chipsets, exposing low-level driver statistics for the Atheros radio driver. It provides detailed counters for hardware-level radio events: watchdog timeouts, hardware error interrupts, beacon misses, receive overrun/end-of-list interrupts, and transmit underrun interrupts, along with queue-depth and discard counters for transmitted management frames. This is fundamentally a hardware/driver health monitoring MIB -- rising counts of hardware error interrupts, watchdog timeouts, or beacon misses are strong indicators of RF interference, driver instability, or a failing radio chipset on the wireless link. It is a vendor-specific extension exposing chipset/driver internals rather than depending on a standard wireless MIB, though it complements interface-level counters from IF-MIB. It is typically deployed on Deliberant outdoor wireless bridge/AP hardware used in WISP and point-to-point wireless backhaul deployments, generally obtained via a DLB-ATHDRV-STATS-MIB download for loading into the operator's monitoring stack.
IPNetwork Monitor allows you to monitor SNMP objects defined in DLB-ATHDRV-STATS-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
- Deliberant wireless bridge/access point (Atheros chipset-based)
Monitoring Examples
An operator would poll dlbAthStatsTable/dlbAthStatsEntry for dlbAthWatchdogTimeouts, dlbAthHardwareErrorInterrupts, and dlbAthBeaconMissInterrupts to gauge radio stability on a wireless link. A climbing dlbAthRecvOverrunInterrupts or dlbAthTxmitUnderrunInterrupts count would suggest the radio is struggling to keep up with traffic load or is experiencing RF-level problems, while a rising dlbAthTxQueueFull/dlbAthTxFramesDiscQueueDepth count would reveal frames being dropped due to congestion on the wireless backhaul.
What Can Be Monitored
- watchdog timeout count
- hardware error interrupt count
- beacon miss interrupt count
- receive overrun/EOL interrupt count
- transmit underrun interrupt count
- transmit queue full/discard counts
