300-410 Practice Question: Is troubleshooting a router that is not sending…
A network engineer is troubleshooting a router that is not sending SNMP traps for a specific interface down event. The engineer has an EEM applet configured to send an SNMP trap when the interface goes down. The applet uses event syslog pattern 'LINK-3-UPDOWN' and action snmp-trap. The interface goes down, but no trap is sent. 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 SNMP trap destination is not configured globally.
The EEM applet is triggered by a syslog message, but the syslog message may not be generated for that specific interface, or the SNMP trap action may require additional configuration such as an SNMP community or target host.
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 syslog pattern 'LINK-3-UPDOWN' is incorrect; the correct pattern is 'LINK-5-CHANGED'.
Why it's wrong here
Incorrect because 'LINK-3-UPDOWN' is a valid syslog message for interface state changes.
- ✗
The EEM applet is not registered with the SNMP agent.
Why it's wrong here
Incorrect because EEM applets do not need to be registered with SNMP; they use the SNMP trap action directly.
- ✗
The SNMP trap action requires an SNMP community string to be specified in the applet.
Why it's wrong here
Incorrect because the SNMP trap action uses the global SNMP configuration; however, the trap destination must be configured.
- ✓
The SNMP trap destination is not configured globally.
Why this is correct
Correct because the EEM applet's SNMP trap action sends traps to the configured SNMP trap receivers; if none are configured, the trap is not sent.
