Parameters
rule-id: Specifies a rule ID, in the range of 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 is 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.
counting: Counts the number of times the ACL rule has been matched. In the software version, the device
counts the number of times the ACL rule has been matched no matter whether this keyword is specified.
fragment: Applies the rule only to non-first fragments. A rule without this keyword applies to both
fragments and non-fragments.
logging: Logs matching packets. This function is available only when the application module that uses the
ACL supports the logging function.
source { source-address source-wildcard | any }: Matches a source address. The source-address
source-wildcard arguments represent a source IP address and wildcard mask in dotted decimal notation.
A wildcard mask of zeros specifies a host address. The any keyword represents any source IP address.
time-range time-range-name: Specifies a time range for the rule. The time-range-name argument is a
case-insensitive string of 1 to 32 characters. It must start with an English letter. If the time range is not
configured, the system creates the rule. However, the rule using the time range can take effect only after
you configure the timer range.
vpn-instance vpn-instance-name: Applies the rule to packets in a VPN instance. The vpn-instance-name
argument is a case-sensitive string of 1 to 31 characters. If no VPN instance is specified, the rule applies
only to non-VPN packets.
Usage guidelines
Within an ACL, the permit or deny statement of each rule must be unique. If the ACL rule you are creating
or editing has the same deny or permit statement as another rule in the ACL, your creation or editing
attempt fails.
To view rules in an ACL and their rule IDs, use the display acl all command.
