Usage Guidelines

Usage Scenario

The step is the difference between rule IDs when the system automatically assigns rule IDs. For example, if the ACL step value is set to 5, rules are numbered 5, 10, 15, and so on.

To add a rule between existing rules, you need to reset the step. For example, an ACL in config mode contains three rules with IDs being 5, 10, and 15. To insert a new rule after rule 5 (the first rule), run the rule 7 xxxx command to insert rule 7.

If the step value is changed, ACL rule IDs are arranged automatically. For example, if the original rule IDs are 5, 10, and 15, the rule IDs become 2, 4, and 6 after you change the step value to 2.


The undo step command can be used to realign ACL rule IDs immediately based on the default step. For example, ACL rule group 3001 contains four rules with IDs being 1, 3, 5, and 7, and the step is 2. After the undo step command is executed, the rule IDs become 5, 10, 15, and 20 and the step value is restored to 5.


An ACL has been created by running the acl command.
