A network engineer runs the following command to verify NetFlow export destination:
R1# show ip flow export
Flow export v9 is enabled for main cache Export source and destination details : VRF ID : Default Destination(1) 192.168.1.100 (2055) Source IP 10.0.0.1 Origin AS 65000 Peer AS 65001 Mask for source 255.255.255.255 Mask for destination 255.255.255.255 Version 9 flow records 1234 flows exported in 567 udp datagrams 0 flows failed due to lack of export packet 0 export packets were sent up to process level 0 export packets were dropped due to no fib 0 export packets were dropped due to adjacency issues 0 export packets were dropped due to fragmentation failures 0 export packets were dropped due to encapsulation fixup failures
What does this output indicate?
⚠ Common exam trap
300-410 often tests reading show command output; candidates may misinterpret the counters or overlook that all error counters are zero.
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
✓
NetFlow export is successful with 1234 flows exported and no errors.
The output shows '1234 flows exported in 567 udp datagrams' and all error counters are zero, indicating successful export. The destination is 192.168.1.100 on port 2055, and version 9 is used. Therefore, NetFlow export is working without errors.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NetFlow export is failing due to adjacency issues.
Why it's wrong here
The counter 'export packets were dropped due to adjacency issues' reads zero, so no adjacency-related drops occurred and export is functioning. It is tempting because adjacency problems are a common NetFlow export fault, but the output shows none here.
- ✓
NetFlow export is successful with 1234 flows exported and no errors.
Why this is correct
The counters confirm 1234 flows exported in 567 UDP datagrams with zero failures across every error category, including no-fib, adjacency, fragmentation and encapsulation drops. This demonstrates the NetFlow v9 export to 192.168.1.100 on port 2055 is functioning without loss.
- ✗
NetFlow is using version 5 export.
Why it's wrong here
The output explicitly states "Flow export v9 is enabled" and "Version 9 flow records", so version 5 is not in use. Version 5 is tempting because it remains a common legacy export format, and would be the correct answer had the output shown "Version 5 flow records" instead.
- ✗
The export destination is not configured.
Why it's wrong here
A destination is explicitly listed as 192.168.1.100 on port 2055, and 567 UDP datagrams were exported, so configuration exists and works. It is tempting because zero drops can suggest nothing is being sent, but the export counters disprove that.
