Parameters
rule-id
: Specifies a rule ID, which ranges from 0 to 65534. If no rule ID is provided when you create an
ACL rule, the system automatically assigns it a rule ID. This rule ID takes the nearest higher multiple of the
numbering step to the current highest rule ID, starting from 0. For example, if the rule numbering step is
5 and the current highest rule ID is 28, the rule is numbered 30.
deny
: Denies matching packets.
permit
: Allows matching packets to pass.
protocol
