2.

Create an IPv4 advanced ACL
and enter its view.

acl number acl-number [ name
acl-name ] [ match-order { auto |

config } ]

By default, no ACL exists.
IPv4 advanced ACLs are

numbered in the range of 3000 to
3999.
You can use the acl name acl-name
command to enter the view of a

named ACL.

3.

(Optional.) Configure a
description for the IPv4

advanced ACL.

description text

By default, an IPv4 advanced 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 }
protocol [ { { ack ack-value | fin

fin-value | psh psh-value | rst

rst-value | syn syn-value | urg
urg-value } * | established } |

counting | destination

{ dest-address dest-wildcard |
any } | destination-port operator

port1 [ port2 ] | { dscp dscp |

{ precedence precedence | tos tos }
* } | fragment | icmp-type

{ icmp-type [ icmp-code ] |

icmp-message } | logging | source
{ source-address source-wildcard |

any } | source-port operator port1

[ port2 ] | time-range

time-range-name ] *

By default, an IPv4 advanced 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 neq for the operator
argument.

6.

(Optional.) Add or edit a rule
comment.

rule rule-id comment text

By default, no rule comments are
configured.

Configuring an IPv6 advanced ACL

IPv6 advanced ACLs match packets based on the source IPv6 addresses, destination IPv6 addresses,

packet priorities, protocol numbers, and other protocol header fields such as the TCP/UDP source port
number, TCP/UDP destination port number, ICMPv6 message type, and ICMPv6 message code.
Compared to IPv6 basic ACLs, IPv6 advanced ACLs allow more flexible and accurate filtering.
