A network engineer runs the following command on Router R1:
R1# show flow monitor FLOW-MONITOR-1 cache format table
Cache type: Normal Cache size: 1000 Current entries: 1000 High Watermark: 1000
Flows added: 50000 Flows aged: 49000 - Active timeout (1800 secs) 40000 - Inactive timeout (15 secs) 8000 - Event aged 0 - Watermark aged 1000 - Emergency aged 0
Based on this output, what is the most likely issue?
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 cache size is too small, causing watermark aging and potential loss of flow data.
The cache is full (1000 current entries, high watermark 1000), and watermark aging has occurred (1000 flows aged due to watermark). This indicates the cache is overflowing, causing flows to be aged prematurely to make room for new flows. This can lead to incomplete data.
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 cache size is too small, causing watermark aging and potential loss of flow data.
Why this is correct
The cache is full and watermark aging is occurring, meaning flows are being aged out due to lack of space, which can result in incomplete export data.
- ✗
The active timeout is set too low at 1800 seconds.
Why it's wrong here
1800 seconds is the default; the issue is cache overflow, not timeout.
- ✗
The inactive timeout is set too low at 15 seconds.
Why it's wrong here
15 seconds is default; the issue is cache overflow.
- ✗
The flow exporter is not configured.
Why it's wrong here
The exporter status is not shown; the issue is cache capacity.
