Parameters

Parameter	Description	Value
basic-acl-name	Creates a basic ACL with a name.	The value is a string of 1 to 64 case-sensitive characters, spaces not supported. The name must start with a letter or digit, and cannot contain only digits.
basic	Creates a basic ACL with a keyword.	-
match-order	Indicates the order in which basic ACL rules are matched.	-
config	Indicates the configuration order, meaning that ACL rules are matched in the order they are configured. This mechanism applies only when rule numbers are not specified. If rule numbers are specified, the ACL rules are matched based on the numbers in ascending order.	-
auto	Indicates the automatic order, meaning that ACL rules are matched based on the depth-first principle. The depth-first principle matches ACL rules based on how precise the rules are. The more matching criteria an ACL rule contains, the more precise the rule is. If two rules have the same precision, they are matched in the order they are configured.	-
number basic-acl-number	Creates a basic ACL with a number.	The value is an integer ranging from 2000 to 2999.

Usage Guidelines

Usage Scenario

A basic ACL defines rules for filtering packets based on the source IP addresses of packets. To create a basic ACL, run the acl command.

Configuration Impact

The undo acl all command deletes all types of ACLs on a device. If the ACLs being deleted are applied to services, these services are interrupted. Before deleting an ACL, ensure that the ACL is not referenced by services.

Follow-up Procedure

Run the rule command to configure a rule for a created basic ACL. Then the ACL rule can be applied to match packets.

Run the description command to configure a description for a created basic ACL. The description can contain the functions of the basic ACL, facilitating applications.

Example

# Create a basic ACL named basic-acl.
