ACL configuration commands
acl
Syntax
acl number acl-number [ name acl-name ] [ match-order { auto | config } ]
undo acl { all | name acl-name | number acl-number }
View
System view
Default level
2: System level
Parameters
number acl-number: Specifies the number of an access control list (ACL):
•2000 to 2999 for IPv4 basic ACLs
•3000 to 3999 for IPv4 advanced ACLs
•4000 to 4999 for Ethernet frame header ACLs
name acl-name: Assigns a name to the ACL for easy identification. The acl-name argument takes a
case-insensitive string of 1 to 63 characters. It must start with an English letter, and to avoid confusion,
cannot be all.
match-order: Sets the order in which ACL rules are compared against packets:
•auto—Compares ACL rules in depth-first order. The depth-first order differs with ACL categories. For
more information, see ACL and QoS Configuration Guide.
•config—Compares ACL rules in ascending order of rule ID. The rule with a smaller ID has higher
priority. If no match order is specified, the config order applies by default.
all: Deletes all IPv4 ACLs and Ethernet frame header ACLs.
Description
Use acl to create an IPv4 ACL or an Ethernet frame header ACL, and enter its view. If the ACL has been
created, you enter its view directly.
Use undo acl to delete the specified IPv4 or Ethernet frame header ACL, or all IPv4 and Ethernet frame
header ACLs.
By default, no ACL exists.
You can assign a name to an IPv4 or Ethernet frame header ACL only when you create it. After an ACL
is created with a name, you cannot rename it or remove its name.
You can change match order only for ACLs that do not contain any rules.
To display any ACLs you have created, use the display acl command.
Examples
# Create IPv4 basic ACL 2000, and enter its view.
<Sysname> system-view

[Sysname] acl number 2000
[Sysname-acl-basic-2000]
# Create IPv4 basic ACL 2001 with the name flow, and enter its view.

acl copy
Syntax
acl copy { source-acl-number | name source-acl-name } to { dest-acl-number | name dest-acl-name }
View
System view
Default level
2: System level
Parameters
source-acl-number: Specifies an existing source ACL by its number:
•2000 to 2999 for IPv4 basic ACLs
•3000 to 3999 for IPv4 advanced ACLs
•4000 to 4999 for Ethernet frame header ACLs
name source-acl-name: Specifies an existing source ACL by its name. The source-acl-name argument
takes a case-insensitive string of 1 to 63 characters.
dest-acl-number: Assigns a unique number to the ACL you are creating. This number must be from the
same ACL category as the source ACL. Available value ranges include:
•2000 to 2999 for IPv4 basic ACLs
•3000 to 3999 for IPv4 advanced ACLs
•4000 to 4999 for Ethernet frame header ACLs
name dest-acl-name: Assigns a unique name to the ACL you are creating. The dest-acl-name takes a
case-insensitive string of 1 to 63 characters. It must start with an English letter and to avoid confusion,
cannot be all. For this ACL, the system automatically picks the smallest number from all available
numbers in the same ACL category as the source ACL.
Description
Use acl copy to create an IPv4 or an Ethernet frame header ACL by copying an ACL that already exists.
The new ACL has the same properties and content as the source ACL, but not the same ACL number and
name.
You can assign a name for an ACL only when you create it. After an ACL is created with a name, you
cannot rename it or remove its name.
Examples
# Create IPv4 basic ACL 2002 by copying IPv4 basic ACL 2001.
<Sysname> system-view
[Sysname] acl copy 2001 to 2002

3
acl ipv6
Syntax
acl ipv6 number acl6-number [ name acl6-name ] [ match-order { auto | config } ]
undo acl ipv6 { all | name acl6-name | number acl6-number }
View
System view
Default level
2: System level
Parameters
number acl6-number: Specifies the number of an IPv6 ACL:
•2000 to 2999 for IPv6 basic ACLs
•3000 to 3999 for IPv6 advanced ACLs
name acl6-name: Assigns a name to the IPv6 ACL for easy identification. The acl6-name argument takes
a case-insensitive string of 1 to 63 characters. It must start with an English letter, and to avoid confusion,
cannot be all.
match-order: Sets the order in which ACL rules are compared against packets:
•auto—Compares ACL rules in depth-first order. The depth-first order differs with ACL categories. For
more information, see ACL and QoS Configuration Guide.
•config—Compares ACL rules in ascending order of rule ID. The rule with a smaller ID has higher
priority. If no match order is specified, the config order applies by default.
all: Delete all IPv6 ACLs.
Description
Use acl ipv6 to create an IPv6 ACL and enter its ACL view. If the ACL has been created, you enter its view
directly.
Use undo acl ipv6 to delete the specified IPv6 ACL or all IPv6 ACLs.
By default, no ACL exists.
You can assign a name to an IPv6 ACL only when you create it. After an IPv6 ACL is created, you cannot
rename it or remove its name.
You can change match order only for ACLs that do not contain any rules.
To display any ACLs you have created, use the display acl ipv6 command.
Examples
# Create IPv6 ACL 2000 and enter its view.
<Sysname> system-view
[Sysname] acl ipv6 number 2000
[Sysname-acl6-basic-2000]
# Create IPv6 basic ACL 2001 with the name flow, and enter its view.

are not supported.
inbound: Specifies the inbound direction.
outbound: Specifies the outbound direction.
interface vlan-interface vlan-interface-number: Specifies a VLAN interface by its number.
slot slot-number: Specifies an IRF member switch. The slot-number argument is the ID of the IRF member

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Description
Use display packet-filter to display whether an ACL has been successfully applied to an interface for
packet filtering.
•The ACL application status may be different on the master and on an IRF member switch because
of ACL resource insufficiency. You can specify the slot number in the display packet-filter command
to check the ACL application status on the member switch.
•If you specify neither the inbound keyword nor the outbound keyword, the command displays the
application status of both incoming and outgoing packet filtering ACLs.
Examples
# Display the application status of incoming and outgoing packet filtering ACLs for interface
GigabitEthernet 1/0/1.
<Sysname> display packet-filter interface gigabitethernet 1/0/1

hardware-count enable
Syntax

View
IPv4 basic/advanced ACL view, IPv6 basic/advanced ACL view, Ethernet frame header ACL view
Default level
2: System level
Parameters
None
Description
Use hardware-count enable to enable counting ACL rule matches performed in hardware. The device
automatically counts the rule match counting performed in software.
Use undo hardware-count enable to disable counting ACL rule matches performed in hardware. This
command also resets the hardware match counters for all rules in the ACL. For a rule configured with the
counting keyword, this command only resets the rule’s hardware match counter.
By default, ACL rule matches performed in hardware are not counted.
The hardware-count enable command enables match counting for all rules in an ACL, and the counting
keyword in the rule command enables match counting specific to rules. For an individual rule, rule match
counting works as long as either the hardware-count enable command or the counting keyword is
configured.
When an ACL is referenced by a QoS policy, this command or the counting keyword does not take effect.
No ACL rule matches are counted.
Related commands: display acl, display acl ipv6, and rule.

# Enable rule match counting for IPv4 ACL 2000.
