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 to the ACL for easy identification. The acl-name argument takes a
case-insensitive string of 1 to 32 characters. It must start with an English letter and to avoid confusion, it
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.
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 to an IPv4 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
