E5-111-TRAPS-MIB::voipClockFail #

Clock fault trigger.

Variables #

• voipDevId

Definitions #

voipDevId

The device ID of the DUT. 0 means port 25 to 48, 1 means port 1 to 24.

Here is a runbook for the SNMP trap “E5-111-TRAPS-MIB::voipClockFail”:

Meaning #

The “E5-111-TRAPS-MIB::voipClockFail” trap indicates that a clock fault has been triggered on a VoIP device. This fault can cause issues with call quality, synchronization, and overall VoIP service reliability.

Impact #

The impact of this trap is high, as a clock fault can cause:

• Call quality issues, such as jitter, latency, and dropped calls
• Inaccurate call billing and logging
• Synchronization issues with other network devices
• Downtime and outages of VoIP services

Diagnosis #

To diagnose the issue, follow these steps:

1. Identify the affected device: Use the voipDevId variable to determine which device is experiencing the clock fault. Check the device ID to determine which port range is affected (0 for port 25-48, 1 for port 1-24).
2. Check device logs: Review the device logs to determine when the clock fault occurred and if there are any related error messages.
3. Verify clock synchronization: Check if the device is properly synchronized with an external clock source or if the clock is running in a standalone mode.
4. Check for hardware issues: Perform a visual inspection of the device to identify any signs of hardware failure, such as overheating or physical damage.

Mitigation #

To mitigate the issue, follow these steps:

1. Reset the device: Attempt to reset the device to restore clock synchronization.
2. Replace the device: If the issue persists, replace the faulty device to prevent further disruptions to VoIP services.
3. Verify clock configuration: Verify that the clock configuration is correct and that the device is properly synchronized with an external clock source.
4. Monitor for recurrences: Continuously monitor the device for recurrences of the clock fault and take proactive measures to prevent future occurrences.
