Question 1,812 of 2,152
Local SPAN: Monitoring Interface Traffic with Source Both
This 300-410 practice question tests your understanding of span, rspan, and erspan. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Consider the following partial configuration on a Cisco IOS-XE switch:
monitor session 1 source interface GigabitEthernet1/0/1 both monitor session 1 destination interface GigabitEthernet1/0/2
What is the effect of this configuration?
Quick Answer
The answer is that it copies all traffic received and transmitted on GigabitEthernet1/0/1 to GigabitEthernet1/0/2. This is correct because the keyword "both" in the source interface configuration specifies that the local SPAN session will monitor both ingress and egress traffic, duplicating every packet entering or leaving the source port and forwarding it out the destination port for analysis. On the Cisco CCNP ENARSI 300-410 exam, this question tests your understanding of local SPAN interface configuration effects, often appearing in troubleshooting or design scenarios where you must distinguish between "rx", "tx", and "both" options. A common trap is assuming "both" only captures one direction or confusing it with remote SPAN; remember that local SPAN is strictly within the same switch, and the destination port cannot be a source port. For a quick memory tip, think of "both" as "bidirectional" — it mirrors the full conversation, not just half of it.
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
✓
It copies all traffic received and transmitted on GigabitEthernet1/0/1 to GigabitEthernet1/0/2.
This configures a local SPAN session that copies traffic from GigabitEthernet1/0/1 (both ingress and egress) to GigabitEthernet1/0/2 for monitoring.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It copies all traffic received and transmitted on GigabitEthernet1/0/1 to GigabitEthernet1/0/2.
Why this is correct
The 'both' keyword specifies both ingress and egress traffic.

Why it's wrong here
Source and destination are clearly defined; direction is from source to destination.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
