Description Use the rule command to define or modify an advanced IPv4 ACL rule. If the rule does not exist, it is created first.

Use the undo rule command to remove an advanced ACL rule or parameters from the rule.

With the undo rule command, if no parameters are specified, the entire ACL rule is removed; if other parameters are specified, only the involved information is removed.

You will fail to create or modify a rule if its permit/deny statement is exactly the same as another rule. In addition, if the ACL match order is set to auto rather than config, you cannot modify ACL rules.
