Default Level
2: System level
Parameters
number: Defines a numbered IPv6 ACL.
acl6-number: IPv6 ACL number, which must be in the following ranges:
2000 to 2999 for basic IPv6 ACLs
3000 to 3999 for advanced IPv6 ACLs
name acl6-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. For how depth-first match works, refer to the "IPv6 ACL Match
Order" section in accompanied ACL Configuration.
config: Performs matching against rules in the order in which they are configured.
all: All IPv6 ACLs.
Description
Use the acl ipv6 command to enter IPv6 ACL view. If the ACL does not exist, it is created first.
Use the undo acl ipv6 command to remove a specified or all IPv6 ACLs.
By default, the match order is config.
Note that:
The match order setting is not available for simple IPv6 ACLs, because a simple IPv6 ACL can
contain only one rule.
You can specify a name for an IPv6 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 IPv6 ACL must be unique among IPv6 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 IPv6 ACL but only when it
is empty.
Examples
# Create IPv6 ACL 2000.
<Sysname> system-view
[Sysname] acl ipv6 number 2000
[Sysname-acl6-basic-2000]
# Create IPv6 ACL 2002, giving the ACL a name of flow.
<Sysname> system-view
[Sysname] acl ipv6 number 2002 name flow
[Sysname-acl6-basic-2002-flow]
# Enter the view of an IPv6 ACL that has no name by specifying its number.
<Sysname> system-view
[Sysname] acl ipv6 number 2000
