300-410 Practice Question: The default CoPP aggregate policer rate for…
What is the default CoPP aggregate policer rate for control plane traffic on a Cisco IOS-XE device?
⚠ Common exam trap
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.

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
✓
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
32000 bps
Why it's wrong here
No default rate exists for CoPP; it must be explicitly configured.
- ✗
75000 bps
Why it's wrong here
No default rate exists for CoPP; it must be explicitly configured.
- ✓
No default rate; CoPP is disabled by default
Why this is correct
CoPP is not enabled by default on Cisco IOS-XE; the administrator must configure a policy-map and apply it to the control plane.
- ✗
128000 bps
Why it's wrong here
No default rate exists for CoPP; it must be explicitly configured.
