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
The default CoPP aggregate policer rate on IOS-XE is 8000 bps, not 32000 bps. It is tempting because 32000 bps appears as a per-protocol policer value in some CoPP configurations, so it is the correct figure when a question asks about an individual class rather than the aggregate policer.
- ✗
75000 bps
Why it's wrong here
The default CoPP aggregate policer rate on IOS-XE is 8000 bps, not 75000 bps. It is tempting because 75000 bps is a commonly cited control-plane threshold in older documentation, making it the right answer when a question references that legacy value rather than the IOS-XE aggregate default.
- ✓
No default rate; CoPP is disabled by default
Why this is correct
Cisco IOS-XE ships with no default CoPP aggregate policer rate because control plane policing is disabled until explicitly configured. The aggregate policer only exists once an administrator defines a policy-map and attaches it to the control plane.
- ✗
128000 bps
Why it's wrong here
The default CoPP aggregate policer rate on IOS-XE is 8000 bps, not 128000 bps. It is tempting because 128000 bps appears as a configured aggregate value in some CoPP policy examples, so it is correct when the question asks about an explicitly configured rate rather than the platform default.
