300-410 Router R8 is configured with SNMP and IP SLA Practice Question
Router R8 is configured with SNMP and IP SLA. The IP SLA operation sends SNMP traps to the NMS when a threshold is crossed. The configuration includes: ip sla 1, icmp-echo 192.168.1.1, threshold 100, timeout 1000, frequency 10, ip sla schedule 1 life forever start-time now, snmp-server enable traps ip sla. However, the NMS receives no traps when the threshold is crossed. The IP SLA operation shows 'Over threshold' in show ip sla statistics. What is the root cause?
⚠ Common exam trap
Cisco often tests the distinction between enabling SNMP traps globally ('snmp-server enable traps ip sla') and configuring the specific reaction that triggers those traps ('ip sla reaction-configuration'), leading candidates to overlook the missing reaction command.
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 IP SLA operation is missing the 'ip sla reaction-configuration' command to trigger SNMP traps when the threshold is exceeded.
The 'ip sla reaction-configuration' command is required to define the condition (e.g., threshold violation) that triggers an SNMP trap. Without this command, the IP SLA operation can detect and report 'Over threshold' in statistics, but it has no mechanism to generate an SNMP trap to the NMS. The 'snmp-server enable traps ip sla' command only enables the router to send IP SLA traps globally; it does not link a specific reaction to the threshold event.
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 IP SLA operation is missing the 'ip sla reaction-configuration' command to trigger SNMP traps when the threshold is exceeded.
Why this is correct
IP SLA traps require a reaction configuration that specifies the threshold and action (e.g., 'ip sla reaction-configuration 1 react timeout threshold 100 action trapOnly'). Without it, no traps are sent.
- ✗
The NMS is not configured to receive IP SLA traps.
Why it's wrong here
The NMS receives all traps, but the router is not generating them.
- ✗
The SNMP community string is incorrect for trap sending.
Why it's wrong here
The community string is configured globally, and the NMS can poll, so community is fine.
- ✗
The IP SLA operation is not scheduled correctly.
Why it's wrong here
The operation shows 'Over threshold', so it is running and detecting threshold crossings.
