source { source-address source-wildcard | any }: Matches a source address. The source-address

source-wildcard arguments represent a source IP address and wildcard mask in dotted decimal notation.

A wildcard mask of zeros specifies a host address. The any keyword represents any source IP address.

time-range time-range-name: Specifies a time range for the rule. The time-range-name argument is a

case-insensitive string of 1 to 32 characters. It must start with an English letter. If the time range is not

configured, the system creates the rule. However, the rule using the time range can take effect only after

you configure the timer range. For more information about time range, see ACL and QoS Configuration

Guide.

vpn-instance vpn-instance-name: Applies the rule to a VPN instance. The vpn-instance-name argument is

a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, the rule applies only

to non-VPN packets.

Usage guidelines

If an ACL is for outbound QoS traffic classification or outbound packet filtering, do not specify the

vpn-instance keyword.

Within an ACL, the permit or deny statement of each rule must be unique. If the ACL rule you are creating

or editing has the same deny or permit statement as another rule in the ACL, the rule will not be created

or changed.

You can edit ACL rules only when the match order is config.

• If you do not specify any optional keywords, the undo rule command deletes the entire rule.

• If you specify optional keywords or arguments, the undo rule command deletes the specified

attributes.

To view rules in an ACL and their rule IDs, use the display acl all command.

Examples

# Create a rule in IPv4 basic ACL 2000 to deny the packets from any source IP segment but 10.0.0.0/8,

172.17.0.0/16, or 192.168.1.0/24.

<Sysname> system-view

[Sysname] acl number 2000

[Sysname-acl-basic-2000] rule permit source 10.0.0.0 0.255.255.255

[Sysname-acl-basic-2000] rule permit source 172.17.0.0 0.0.255.255

[Sysname-acl-basic-2000] rule permit source 192.168.1.0 0.0.0.255

[Sysname-acl-basic-2000] rule deny source any
