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.
3. (Optional.) Configure a
description for the IPv4 basic
ACL.

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.
If an ACL is for outbound QoS
traffic classification or outbound
packet filtering, do not specify the
vpn-instance
keyword.
6. (Optional.) Add or edit a rule
comment.

By default, no rule comments are
configured.
Configuring an IPv6 basic ACL
IPv6 basic ACLs match packets based only on source IP addresses.
To configure an IPv6 basic ACL:
