Description
Use the rule command to define an ACL rule.
Use the undo rule command to delete an ACL rule.
Before you can delete a rule, you must specify the rule ID. If you do not know the rule ID,
you can view it by using the display acl config command.
In the case that you specify the rule ID when defining a rule:
z If the ACL is created with the config keyword specified and the rule identified by
the rule-id argument exists, the settings specified in the rule command overwrite
the counterparts of the existing rule (other settings of the rule remain unchanged).
If the ACL is created with the auto keyword specified, the rules of the ACL cannot
be edited. In this case, the system prompts errors when you execute the rule
command.
z If the rule corresponding to the specified rule ID does not exist, you will create and
define a new rule.
z The content of a modified or created rule must not be identical with the content of
any existing rule; otherwise the rule modification or creation will be failed, and the
system will prompt that the rule already exists.
If you do not specify a rule ID, you will create and define a new rule, and the system will
assign an ID for the rule automatically.
Examples
