NOTE:
The Web interface does not support ACL step configuration.
Meaning of the step
The step defines the difference between two neighboring numbers that are automatically assigned to
ACL rules by the device. For example, with a step of 5, rules are automatically numbered 0, 5, 10, 15,
and so on. By default, the step is 5.
Whenever the step changes, the rules are renumbered, starting from 0. For example, if four rules are
numbered 0, 5, 10, and 15 respectively, changing the step from 5 to 2 will cause the rules to be
renumbered 0, 2, 4, and 6.
Benefits of using the step
With the step and rule numbering/renumbering mechanism, you do not need to assign numbers to rules
when defining them. The system will assign a newly defined rule a number that is the smallest multiple of
the step bigger than the current biggest number. For example, with a step of five, if the biggest number
is 28, the newly defined rule will get a number of 30. If the ACL has no rule defined already, the first
defined rule will get a number of 0.
Another benefit of using the step is that it allows you to insert new rules between existing ones as needed.
For example, after creating four rules numbered 0, 5, 10, and 15 in an ACL with a step of five, you can
insert a rule numbered 1.
