Configuring an Attack Source Tracing Mode

Configuring an Attack Source Tracing Mode

Context

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.

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 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 attack source tracing modes based on source MAC addresses and source IP addresses are supported.

  5. Run commit

    The configuration is committed.
