2.

Create an IPv6 basic ACL
view and enter its view.

acl ipv6 number acl-number
[ name acl-name ] [ match-order

{ auto | config } ]

By default, no ACL exists.
IPv6 basic ACLs are numbered in

the range of 2000 to 2999.
You can use the acl ipv6 name
acl-name command to enter the

view of a named ACL.

3.

(Optional.) Configure a
description for the IPv6 basic

ACL.

By default, an IPv6 basic ACL has
no ACL description.

4.

(Optional.) Set the rule

numbering step.

step step-value

The default setting is 5.

5.

Create or edit a rule.

rule [ rule-id ] { deny | permit }
[ counting | fragment | logging |

routing [ type routing-type ] |

source { source-address
source-prefix |

source-address/source-prefix |

any } | time-range
time-range-name ] *

By default, an IPv6 basic ACL does
not contain any rule.
The logging keyword takes effect
only when the module (for

example, packet filtering) that uses

the ACL supports logging.
If an ACL is for QoS traffic
classification or packet filtering:

Do not specify the fragment

keyword.

Do not specify the routing

keyword if the ACL is for

outbound QoS traffic
classification or outbound

packet filtering.

6.

(Optional.) Add or edit a rule

comment.

rule rule-id comment text

By default, no rule comments are
configured.

Configuring an advanced ACL

This section describes procedures for configuring IPv4 and IPv6 advanced ACLs.

Configuring an IPv4 advanced ACL

IPv4 advanced ACLs match packets based on source IP addresses, destination IP addresses, packet
priorities, protocol numbers, and other protocol header information, such as TCP/UDP source and

destination port numbers, TCP flags, ICMP message types, and ICMP message codes.
Compared to IPv4 basic ACLs, IPv4 advanced ACLs allow more flexible and accurate filtering.
To configure an IPv4 advanced ACL:
