Huawei VRP ACL Number Ranges: Layer 2 ACLs
Short answer
D A layer 2 ACL value ranges from 4000-4999.
Question
Key Takeaways
The question tests precise memorization of numeric boundaries for ACL types. The main trap is confusing the start/end points of adjacent ranges (e.g., claiming Advanced ACLs go up to 4000 instead of 3999).
Identify the correct Huawei VRP Access Control List (ACL) number range. Layer 2 ACLs utilize the 4000-4999 range, while Basic and Advanced ACLs use 2000-2999 and 3000-3999 respectively.
Common mistake: Option C is a common distractor. Test-takers often misremember the upper limit of Advanced ACLs, thinking they extend into the Layer 2 range or confusing the inclusive/exclusive nature of the ranges.
Expert Analysis
To determine the correct statement, we must evaluate each option against Huawei's Virtual Routing and Forwarding (VRP) platform ACL numbering conventions.
Option A claims an interface ACL value ranges from 1000-2000. This is incorrect; Huawei does not use this specific range for standard ACL definitions. Interface-based configurations typically utilize named ACLs or apply existing numbered ACLs.
Option B states a basic ACL ranges from 1000-2999. This is incorrect because it conflates two distinct types. Basic ACLs are assigned the range 2000–2999. The range 1000–1999 is generally reserved for other internal uses or vendor-specific extensions, not standard basic ACLs.
Option C asserts an advanced ACL ranges from 3000-4000. This is incorrect due to the upper bound. Advanced ACLs occupy the range 3000–3999. Including 4000 incorrectly overlaps with the Layer 2 ACL range.
Option D specifies that a Layer 2 ACL value ranges from 4000-4999. This is correct. In VRP, Layer 2 ACLs (also known as MAC address ACLs) are strictly defined within the 4000–4999 numerical range. This allows network administrators to distinguish between Layer 3 filtering (Basic/Advanced) and Layer 2 filtering based on the ACL number assigned.
Exam Strategy
When studying for H12-811, create a mental map of ACL number blocks rather than memorizing isolated facts. Group them by OSI layer: Layer 2 (4000-4999), Layer 3 Source/Destination (2000-2999 Basic, 3000-3999 Advanced). When reviewing options, check both the lower and upper bounds carefully, as exam questions often shift one boundary by 1 digit to create incorrect statements.
