Configuring a Basic ACL Rule

Configuring a Basic ACL Rule


A basic ACL classifies packets by matching packet information against its rules. After a basic ACL is created, configure rules in the basic ACL.


When the device receives a packet, it matches the packet against ACL rules one by one based on the configuration order. Once the packet matches a rule in an ACL rule group, the device stops the matching process and performs the action specified in the matching rule on the packet.


  1. Run system-view

    The system view is displayed.

  2. Run acl { [ number ] acl-number | name acl-name { [ number ] acl-number | basic } }

    A basic ACL is created and the basic ACL view is displayed.

    The parameter acl-number specifies the number of a basic ACL. The value ranges from 2000 to 2999.

    By default, no ACL is created.

  3. Run rule [ rule-id ] [ name rule-name ] { deny | permit } [ fragment-type fragment | source { source-ip-address { source-wildcard | 0 | src-netmask } | any } | time-range time-name | vpn-instance vpn-instance-name | logging ] *

    Rules for the basic ACL are configured.


    When you configure a basic ACL:

    • If a source address is specified for packets (that is, the source parameter is specified in step 3), the device filters IP packets from this source address or filters the ARP packets carrying this source address.

    • If all source IP addresses are specified (any in Step 3), the system will not check packets' source IP addresses.

    • When you specify the parameter time-range to reference a time range to the ACL, the ACL cannot be bound to the specified time range if the specified time-name does not exist.

  4. (Optional) Run rule rule-id description description

    The description of a basic ACL rule is configured.

    By default, no description is configured for an ACL rule.

    You are not allowed to configure the description for a rule that has not been created.

  5. Run commit

    The configuration is committed.
