Question 2,117 of 2,152
Is There a Default CoPP Aggregate Policer Rate?
This 300-410 practice question tests your understanding of control plane policing (copp). 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.
What is the default CoPP aggregate policer rate for control plane traffic on a Cisco IOS-XE device?
Quick Answer
The answer is that there is no default CoPP aggregate policer rate on Cisco IOS-XE devices; CoPP is disabled by default. This is because Control Plane Policing is a manual security feature that requires explicit configuration through a policy-map and class-map to define which control plane traffic types are permitted, policed, or dropped. Without this configuration, the control plane accepts all traffic without any rate-limiting, meaning the aggregate policer rate is effectively nonexistent until an administrator activates it. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding that CoPP is not a default protection mechanism—a common trap is assuming a built-in rate exists, similar to how CoPP is enabled by default on some other platforms. Remember, IOS-XE treats the control plane as an open door until you lock it with CoPP. A useful memory tip: “No policy, no police”—if you don’t configure a policy-map, CoPP does nothing.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
No default rate; CoPP is disabled by default
Cisco IOS-XE does not enable Control Plane Policing (CoPP) by default; it must be explicitly configured using the 'control-plane' command followed by 'service-policy' to attach a policy map. The absence of a default aggregate policer rate means that without CoPP configuration, the control plane is unprotected from traffic storms or DoS attacks. Options A, B, and D are incorrect because they suggest predefined rates that do not exist as defaults in Cisco IOS-XE.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that CoPP has a built-in default policer rate, leading candidates to confuse it with the default hardware rate limits for control plane queues (e.g., on Catalyst switches) or with default values from other QoS features.
Detailed technical explanation
How to think about this question
CoPP uses MQC (Modular QoS CLI) to classify and police control plane traffic, requiring explicit creation of a class map, policy map, and attachment to the control plane. The 'police' command within the policy map defines the rate and burst parameters; if no police is configured, no policing occurs. In real-world scenarios, an engineer might mistakenly assume a default rate exists and skip verification, leaving the control plane vulnerable until a custom policy is applied.
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.
TExam Day Tips
- 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.
