Usage Guidelines

Usage Scenario

If an attacker sends a large number of UDP packets to the target host in a short time, the target host is busy with these UDP packets. As a result, the target host is overloaded and cannot process normal services. To prevent UDP flood attacks, run the anti-attack udp-flood enable command to enable defense against UDP flood attacks.

The device detects UDP flood attack packets after defense against UDP flood attacks is enabled. The device directly discards UDP flood attack packets.

Precautions

You can also run the anti-attack enable command in the system view to enable attack defense against all attack packets including UDP flood attack packets.

Example

# Enable defense against UDP flood attacks.

<Huawei> system-view
[Huawei] anti-attack udp-flood enable
