Huawei ACL Default Rule ID Increment
Short answer
B The default increment for ACL rules is 5, not 10, as they start at ID 5 and increase by 5.
Question
Key Takeaways
The main trap is confusing ACL rule ID increments (default 5) with Route-Policy node increments (default 10).
This question tests knowledge of Huawei ACL configuration defaults. Correct answer is B because ACL rules default to an increment of 5, not 10.
Common mistake: A common mistake is selecting TRUE because candidates confuse ACL rule numbering with Route-Policy node numbering, which does use an increment of 10.
Expert Analysis
Default ACL Rule Increment
In Huawei networking devices, Access Control Lists (ACLs) are used to define rule sets for traffic filtering or route matching. When a user creates an ACL—whether basic (numbered 2000-2999), advanced (3000-3999), or user-defined (4000-4999)—the system assigns a unique identifier to each rule within that list. This identifier determines the order in which rules are evaluated.
The critical distinction lies between ACL rules and Route-Policy nodes. A Route-Policy uses nodes with default increments of 10 (e.g., node 10, node 20, node 30). However, this behavior does not apply to ACLs. For ACLs, if you do not explicitly specify a rule ID when adding a rule, the system automatically assigns IDs starting from 5, with an increment of 5 for subsequent rules (i.e., 5, 10, 15, 20...).
Therefore, the statement claiming the default increment is 10 is incorrect. The confusion often arises because both ACLs and Route-Policies use numeric identifiers, but their default spacing differs significantly. ACLs start at 5 and increment by 5, whereas Route-Policy nodes start at 10 and increment by 10.
Exam Strategy
When configuring ACLs on Huawei devices, always remember that rule IDs default to 5, 10, 15... If you need precise control over rule ordering, explicitly specify the rule ID during creation. Do not assume the increment is 10; that applies to Route-Policy nodes, not ACL rules. This distinction is vital for troubleshooting and exam scenarios involving policy-based routing.

HCIP Resolutor 👍 1 Answered BUn paso/incremento de 10 es el valor predeterminado utilizado en las route-policy (node 10, node 20), pero no en las reglas de una ACL básica, avanzada o definida por el usuario.
