Configuring a Whitelist

Configuring a Whitelist


A whitelist is a group of authorized users. The device forwards packets from users in the whitelist. You can apply an ACL to a whitelist.


If a blacklist and a whitelist reference the same ACL, the blacklist takes effect.


  1. Run system-view

    The system view is displayed.

  2. Run cpu-defend policy policy-name

    The attack defense policy view is displayed.

  3. Run whitelist whitelist-id acl acl-number

    A whitelist is created.

    A maximum of eight whitelists can be configured in an attack defense policy on the device.

    The ACL applied to a whitelist can be a basic ACL, an advanced ACL, or a Layer 2 ACL. For details on how to create an ACL, see ACL Configuration.

    By default, no whitelist is configured on the device.


    If an ACL applied to a whitelist contains a deny rule, packets matching the ACL are discarded.

    If packets match both a whitelist that references an ACL with a permit rule and a user-defined flow, the user-defined flow does not take effect for the packets. The device limits the rate of these packets using the CPCAR value configured for the corresponding protocol.

    If an ACL has no rule, the whitelist that references the ACL does not take effect.
