Command Reference Guide – ACL Chapter 1 ACL Commands
1-25
z If the rule corresponding to the specified rule ID already exists, you will edit the
rule, and the modified part in the rule will replace the original content, while other
parts remain unchanged.
z If the rule corresponding to the specified rule ID does not exists, 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 fail, 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.
Note:
Only cards other than A type ones support the user-defined ACL.
Example
# Define a rule to forbid all TCP packets to pass through.
