traffic-filter (Interface view)

traffic-filter (Interface view)


The traffic-filter command applies an ACL to an interface to filter packets on the interface.

The undo traffic-filter command cancels the configuration.

By default, no ACL is applied to an interface to filter packets on the interface.


traffic-filter { inbound | outbound } acl { acl-number | name acl-name }

undo traffic-filter { inbound | outbound } acl { acl-number | name acl-name }






Configures ACL-based packet filtering in the inbound direction on an interface.



Configures ACL-based packet filtering in the outbound direction on an interface.



Filters packets based on the IPv4 ACL.



Specifies the number of an ACL.

The IPv4 ACL number ranges from 2000 to 4999 or 6000 to 6999,
  • The value of a basic ACL ranges from 2000 to 2999.
  • The value of an advanced ACL ranges from 3000 to 3999.
  • The value of a Layer 2 ACL ranges from 4000 to 4999.

    Layer 2 ACLs are not supported when this function is configured in the dialer interface view.

  • The value of a user defined ACL ranges from 6000 to 6999.

name acl-name

Filters packets based on a specified named ACL. acl-name specifies the name of the ACL.

The ACL name must exist.

The value range is the same as that of the acl-number parameter.

Usage Guidelines

Usage Scenario

After the traffic-filter command is executed on an interface, the device filters packets matching ACL rules:

  • If the action in an ACL rule is deny, the device discards packets matching the rule.
  • If the action in an ACL rule is permit, the device forwards packets matching the rule.
  • If no rule is matched, packets are allowed to pass through.


A named ACL has been created using the acl name command.


The AD9431DN-24X does not support ACL-based packet filtering in the VLANIF interface view.

The traffic-filter command can reference an ACL with no rule configured. You can configure a rule for the ACL after running this command.

At most eight ACL rules can be configured for packet filtering in one direction. The rules take effect in the sequence in which they are configured. To improve match efficiency, you are advised to configure an ACL rule with a high match probability for packet filtering. When configuring each ACL rule, set a small ID for the rule with a high match probability, reducing the number of times ACL rules are matched and saving resources. To change the sequence in which packets are filtered based on ACLs, delete all related configurations and reconfigure ACL-based packet filtering.
