Description
Use the
step
command to set a rule numbering step for an ACL. The rule numbering step sets the
increment by which the system numbers rules automatically. For example, the default ACL rule numbering
step is 5. If you do not assign IDs to rules you are creating, they are numbered 0, 5, 10, 15, and so on.
The wider the numbering step, the more rules you can insert between two rules. Whenever the step
changes, the rules are renumbered, starting from 0. For example, if there are five rules numbered 5, 10,
13, 15, and 20, changing the step from 5 to 2 causes the rules to be renumbered 0, 2, 4, 6 and 8.
Use the
undo step
command to restore the default.
The default rule numbering step is 5. After you restore the default numbering step by the
undo step
command, the rules are renumbered in steps of 5.
