Huawei VRP ACL Number Ranges: Layer 2 ACLs

H12-811 By islever Editorial Last updated

ACL Principles and Configuration

Short answer

D A layer 2 ACL value ranges from 4000-4999.

Question

What of the following statements is correct regarding Access Control List types and ranges?
  1. An interface ACL value ranges 1000-2000.
  2. A basic ACL value ranges from 1000-2999.
  3. An advanced ACL value ranges from 3000-4000.
  4. A layer 2 ACL value ranges from 4000-4999. Correct Answer

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.

Frequently Asked Questions

What is the number range for Basic ACLs in Huawei VRP?

Basic ACLs use the number range 2000–2999. They filter traffic based only on source IP addresses.

How do I identify an Advanced ACL by its number?

Advanced ACLs are identified by numbers in the range 3000–3999. These ACLs can filter based on source IP, destination IP, protocol, and port numbers.
