Configuring a basic ACL

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

Configuring an IPv4 basic ACL

IPv4 basic ACLs match packets based only on source IP addresses.
To configure an IPv4 basic ACL:

Step

Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Create an IPv4 basic ACL and

enter its view.

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

By default, no ACL exists.
IPv4 basic ACLs are numbered in
the range of 2000 to 2999.
You can use the acl name acl-name
command to enter the view of a

named ACL.

(Optional.) Configure a
description for the IPv4 basic

ACL.

The default setting is 5.

5.

Create or edit a rule.

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

source { source-address

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

By default, an IPv4 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.

comment.

By default, no rule comments are
configured.
