ACL configuration commands

NOTE:

The Layer 3 Ethernet interface in this document refers to the Ethernet port that can perform IP routin

and

inter-VLAN routing. You can set an Ethernet port as a Layer 3 Ethernet interface by using the port

link-mode route command (see the

Layer 2—LAN Switching Configuration Guide

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 IPv4 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 for the IPv4 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 the 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.

Description

Use the acl command to create an IPv4 ACL and enter its view. If the ACL has been created, you enter its

view directly.

Use the undo acl command to delete the specified IPv4 ACL or all IPv4 ACLs.

By default, no ACL exists.

You can assign a name for an IPv4 ACL only when you create it. After a named 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 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.

<Sysname> system-view

[Sysname] acl number 2001 name flow

[Sysname-acl-basic-2001-flow]

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 a source IPv4 ACL that already exists 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 a source IPv4 ACL that already exists 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 for the IPv4 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 for the IPv4 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 the acl copy command to create an IPv4 ACL by copying an IPv4 ACL that already exists. Except for

the number and name (if any), the new ACL has the same configuration as the source ACL.

You can assign a name for an IPv4 ACL only when you create it. After a named IPv4 ACL is created, you

cannot rename it or remove its name.

Examples

# Create IPv4 basic ACL 2002 by copying IPv4 basic ACL 2001.

Parameters

number acl6-number: Specifies the number of an IPv6 ACL:

• 2000 to 2999 for IPv6 basic ACLs

name acl6-name: Assigns a name for 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 the 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 the acl ipv6 command to create an IPv6 ACL and enter its ACL view. If the ACL has been created, you

enter its view directly.

Use the undo acl ipv6 command to delete the specified IPv6 ACL or all IPv6 ACLs.

By default, no ACL exists.

You can assign a name for an IPv6 ACL only when you create it. After a named 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.
