acl-number: IPv4 ACL number, in the range of 2000 to 4999.
2000 to 2999 for basic IPv4 ACLs
3000 to 3999 for advanced IPv4 ACLs
4000 to 4999 for Ethernet frame header ACLs
name acl-name: Specifies the name of the ACL, which is a case insensitive string of 1 to 32 characters.
It must start with an English letter and cannot be the English word of all to avoid confusion.
match-order: Sets the order in which ACL rules are matched.
auto: Performs depth-first match.
config: Performs matching against rules in the order in which they are configured.
all: All IPv4 ACLs.
Description
Use the acl command to enter IPv4 ACL view. If the ACL does not exist, it is created first.
Use the undo acl command to remove a specified or all IPv4 ACLs.
By default, the match order is config.
Note that:
You can specify a name for an IPv4 ACL only when you create the ACL. After creating an ACL, you
cannot specify a name for it, nor can you change or remove the name of the ACL.
The name of an IPv4 ACL must be unique among IPv4 ACLs. However, an IPv4 ACL and an IPv6
ACL can share the same name.
If you specify both an ACL number and an ACL name in one command to enter the view of an
existing ACL, be sure that the ACL number and ACL name identify the same ACL.
You can also use this command to modify the match order of an existing ACL but only when it is
empty.
Examples
# Create IPv4 ACL 2000.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000]
# Create IPv4 ACL 2002, giving the ACL a name of flow.
<Sysname> system-view
[Sysname] acl number 2002 name flow
[Sysname-acl-basic-2002-flow]
# Enter the view of an IPv4 ACL that has no name by specifying its number.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000]
# Enter the view of an IPv4 ACL that has a name by specifying its number.
<Sysname> system-view
[Sysname] acl number 2002
[Sysname-acl-basic-2002-flow]
# Delete the IPv4 ACL with the number of 2000.
