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
- Run system-view
The system view is displayed.
- Run cpu-defend policy policy-name
The attack defense policy view is displayed.
- Run auto-defend enable
Attack source tracing is enabled.
By default, attack source tracing is disabled.
- 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.
- Run commit
