What Is ASCEND-WATCHDOG-MIB?
ASCEND-WATCHDOG-MIB is a proprietary Ascend Communications MIB managing a hardware watchdog timer used to detect and recover from system hangs on Ascend equipment. It exposes configuration data for enabling the watchdog and setting timeout thresholds, along with status/history data on watchdog-triggered resets. This is directly a hardware/software health MIB: it is the mechanism by which the device recovers from an unresponsive CPU or hung process, and its counters and last-reset-cause objects are key indicators of system stability and unexpected reboots. It is typically used alongside general system MIBs (e.g. sysUpTime from the standard SNMPv2-MIB) since a watchdog-triggered reset directly resets the device's uptime counter. It was deployed across Ascend's WAN access and dial-concentrator product lines as a baseline reliability safeguard, with ASCEND-WATCHDOG-MIB SNMP monitoring giving operators a way to confirm whether resets stemmed from the watchdog or a planned reboot.
IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-WATCHDOG-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
- Ascend WAN access router
- Ascend remote-access concentrator
Monitoring Examples
An administrator would poll the watchdog status and reset-history objects (an ascendWatchdogTable/ascendWatchdogEntry style structure, or scalar reset-count/last-cause objects) to check whether the device's uptime has been reset by the watchdog rather than a planned reboot, treating a rising watchdog-triggered reset count as strong evidence of a recurring software hang or firmware bug needing escalation. No sample objects were provided for this MIB, so these names are inferred from the stated watchdog purpose rather than confirmed source identifiers.
What Can Be Monitored
- watchdog enable/disable state
- watchdog timeout threshold
- watchdog-triggered reset count
- last reset cause
- time since last watchdog event
