300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show flow interface GigabitEthernet0/0 Interface GigabitEthernet0/0
FNF: enabled Ingress IPV4/IPV6 flow monitoring: enabled Exporter: EXPORTER1 Monitor: MONITOR1 Egress IPV4/IPV6 flow monitoring: disabled Ingress MPLS flow monitoring: disabled Egress MPLS flow monitoring: disabled
Based on this output, what is the state of NetFlow on this interface?
⚠ Common exam trap
The trap here is that candidates see 'FNF: enabled' and assume full bidirectional NetFlow, missing the specific ingress/egress status lines that reveal only one direction is active.
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 is only monitoring incoming traffic on this interface.
The output shows that ingress IPv4/IPv6 flow monitoring is enabled with an exporter and monitor configured, while egress IPv4/IPv6 flow monitoring is disabled. This means NetFlow is only monitoring incoming traffic on the interface, not outgoing traffic. The FNF (Flexible NetFlow) status confirms NetFlow is operational, but only for ingress direction.
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 is fully enabled for both ingress and egress traffic.
Why it's wrong here
The output shows ingress IPv4/IPv6 flow monitoring enabled but egress IPv4/IPv6, ingress MPLS and egress MPLS all disabled, so monitoring is one-directional only. It is tempting because 'FNF: enabled' appears, but that global flag does not mean both directions are actively monitored.
- ✓
NetFlow is only monitoring incoming traffic on this interface.
Why this is correct
Ingress IPv4/IPv6 flow monitoring is enabled and bound to EXPORTER1 and MONITOR1, while egress IPv4/IPv6 and both MPLS directions are disabled. Flexible NetFlow therefore records only traffic arriving on GigabitEthernet0/0, satisfying the stem's requirement to identify the interface's actual monitoring state.
- ✗
NetFlow is not configured on this interface.
Why it's wrong here
The output explicitly shows 'FNF: enabled' with ingress IPv4/IPv6 flow monitoring enabled and a named exporter and monitor, so NetFlow is configured and active. It is tempting to assume configuration is absent, but the presence of EXPORTER1 and MONITOR1 confirms it is applied.
- ✗
NetFlow is only monitoring MPLS traffic.
Why it's wrong here
The output shows ingress IPv4/IPv6 flow monitoring enabled while both ingress and egress MPLS flow monitoring are disabled, so no MPLS traffic is being monitored. It is tempting because MPLS flow monitoring is a genuine NetFlow capability, and it would be the correct answer on an interface where only the MPLS monitoring lines read enabled.
