Usage Guidelines

Usage Scenario

The description command configures a description for an ACL in any of the following situations:

A large number of ACLs are configured, and their functions are difficult to identify.
An ACL is used at a long interval, and its function may be left forgotten.
Names of named ACLs cannot fully explain the ACLs' functions.

Precautions

If the description of an ACL rule is not configured, the ACL rule may be misunderstood or misused.

Example

# Configure a description for an ACL numbered 3100.

<HUAWEI> system-view
[~HUAWEI] acl 3100
[*HUAWEI-acl4-advance-3100] description This acl is used in GigabitEthernet 0/1/0
