300-410 Practice Question: Is troubleshooting a router that is not…
A network engineer is troubleshooting a router that is not generating any syslog messages at all, even for critical events like interface flaps. The 'show logging' output shows 'Syslog logging: disabled'. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The 'logging on' command is not configured.
The 'show logging' output clearly states that syslog logging is disabled. The most common cause is that the global 'logging on' command is missing from the configuration. Without this command, no syslog messages are generated or sent to any destination.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The 'logging on' command is not configured.
Why this is correct
Correct because 'logging on' globally enables syslog; without it, no messages are produced.
- ✗
The logging buffer is full and needs to be cleared.
Why it's wrong here
Incorrect because a full buffer does not disable syslog; it only prevents new messages from being stored locally.
- ✗
The router has run out of memory to generate syslog messages.
Why it's wrong here
Incorrect because memory exhaustion would cause other symptoms, and 'show logging' would not show 'disabled'.
- ✗
The 'logging host' command is missing, so no destination is configured.
Why it's wrong here
Incorrect because even without a remote host, local logging to buffer or console would still work if 'logging on' is enabled.
