Configuring a Blacklist

Configuring a Blacklist

Context

A blacklist is a group of users with particular characteristics. The device discards packets from users in the blacklist. You can apply an ACL to a blacklist.

On switches except the CE6870EI and CE6875EI, the following parameters cannot be specified for the ACL referenced by a blacklist. Otherwise, the blacklist is invalid.
  • Basic ACL: vpn-instance
  • Advanced ACL: vpn-instance
    NOTE:

    The CE5880EI and CE6880EI do not support the icmp-type and igmp-type parameters in advanced ACLs.

  • Layer 2 ACL: 802.3
  • Basic ACL6: vpn-instance
  • Advanced ACL6: destination, dscp, and vpn-instance
On the CE6870EI and CE6875EI, only the following parameters can be specified for the ACL referenced by a blacklist. If other parameters are specified, the blacklist is invalid.
  • Basic ACL: source, time-range
  • Advanced ACL: protocol, source, time-range, ttl-expired, source-port, destination-port, igmp-type
  • Layer 2 ACL: source-mac, time-range, type, vlan
  • Basic ACL6: source, time-range
  • Advanced ACL6: protocol, source, time-range, source-port, icmp6-type, destination-port
NOTE:

For the CE6870EI running V200R002C50 and later versions, the blacklist no longer supports advanced ACLs with the source port number and TCP flag as matching rules. If a blacklist using the source port number or TCP flag as a matching rule is configured on a switch running a version earlier than V200R002C50, the blacklist becomes invalid after the switch is upgraded to V200R002C50 or a later version.

Procedure

  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 blacklist blacklist-id acl { acl-number | ipv6 acl6-number } [ interface { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-8> ] [ vlan { vlan-id1 [ to vlan-id2 ] } &<1-8> ]

    A blacklist is created.

    A maximum of eight blacklists can be configured on the device.

    The ACL applied to a blacklist can be a basic ACL, an advanced ACL, an ARP-based ACL, a basic ACL6, an advanced ACL6, or a Layer 2 ACL. For details on how to create an ACL, see ACL Configuration.

    By default, no blacklist is configured on the device.

    NOTE:

    During configuration restoration, the blacklists are restored in the ascending order of blacklist IDs (blacklist-id).

    For CE6870EI and CE6875EI, the ACL applied to a blacklist cannot be an ARP-based ACL.

  4. Run commit

    The configuration is committed.
