Configuring an Attack Source Tracing Mode

Configuring an Attack Source Tracing Mode


After attack source tracing is enabled, you need to set a mode in which the device traces attack sources. The device supports the following attack source tracing modes:
  • Source IP address-based tracing: prevents Layer 3 attack packets.
  • Source MAC address-based tracing: prevents Layer 2 attack packets with a fixed source MAC address.
  • Tracing based on a combination of source port and VLAN: prevents Layer 2 attack packets with different source MAC addresses.


  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 auto-defend enable

    Attack source tracing is enabled.

    By default, attack source tracing is disabled.

  4. Run auto-defend trace-type { source-ip | source-mac | source-portvlan } *

    The attack source tracing mode is specified.

    By default, the device traces attack sources based on source MAC addresses, source IP addresses, and a combination of source ports+VLANs.
