H3C S6812 Series Command Reference Manual page 1539

counting: Counts the times that the rule is matched. If you do not specify this keyword, matches for
the rule are not counted.
fragment: Applies the rule only to non-first fragments. If you do not specify this keyword, the rule
applies to both fragments and non-fragments. If an ACL is applied for packet filtering, do not specify
this keyword.
logging: Logs matching packets. This feature is available only when the application module (for
example, packet filtering) that uses the ACL supports the logging feature.
source { source-address source-wildcard | any }: Matches a source address. The source-address
and source-wildcard arguments specify a source IP address and a wildcard mask in dotted decimal
notation. A wildcard mask of zeros represents 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 time range. For more information about time range, see ACL and QoS
Configuration Guide.
Usage guidelines
Within an ACL, the permit or deny statement of each rule must be unique. If the rule you are creating
or editing has the same deny or permit statement as another rule in the ACL, the rule will not be
created or changed.
You can edit ACL rules only when the match order is config.
To view the existing IPv4 basic and advanced ACL rules, use the display acl all command.
The rule ID is required in the undo rule rule-id command.
If you do not specify optional parameters, the undo rule rule-id command deletes the entire rule. If
you specify optional parameters, the undo rule rule-id command deletes the specified attributes.
The undo rule { deny | permit } command can only be used to delete the entire rule. You must
specify all the attributes of the rule for the command.
The counting keyword in this command enables match counting specific to rules, and the
hardware-count keyword in the packet-filter command enables match counting for all rules in an
ACL.
Examples
# Create a rule in IPv4 basic ACL 2000 to deny the packets from any source IP subnet but 10.0.0.0/8,
172.17.0.0/16, or 192.168.1.0/24.
