300-410 Question 272
Select 3A network engineer is troubleshooting intermittent connectivity issues reported by users in a branch office. The engineer has enabled logging on the router and is trying to pinpoint the problem using conditional debugs. However, the logs are not showing any significant information. Which of the following steps should the engineer take to ensure useful debug information is captured?
- A
Enable timestamps on the logging output.
- B
Increase the logging level to capture more detailed events.
- C
Verify that the debug condition matches the traffic being analyzed.
- D
Send the debug output to a syslog server for easier analysis.
- E
Restart the router to reset the logging buffer.
Show answer and explanation
Correct answers: A, B, C
Explanation
To effectively troubleshoot using logging and debugs, it is important to ensure timestamps are enabled for time correlation, adjust the logging level to capture detailed events, and verify that the debug condition matches the traffic being analyzed. These steps will ensure that the logs provide meaningful information for root cause analysis.
- A. Correct.
Enabling timestamps on the logging output helps correlate log events with specific time periods, which is critical for troubleshooting intermittent issues.
- B. Correct.
Increasing the logging level ensures more detailed events are captured, which can reveal the source of the issue.
- C. Correct.
Conditional debugs require that the specified condition matches the traffic being analyzed. If the condition is incorrect or unmatched, no debug output will be generated.
- D. Incorrect.
While sending debug output to a syslog server can facilitate analysis, it does not directly address the issue of logs not showing significant information.
- E. Incorrect.
Restarting the router is unnecessary in this scenario and does not help in capturing more useful debug information.
