The anti-attack udp-flood enable command enables defense against UDP flood attacks.
The undo anti-attack udp-flood enable command disables defense against UDP flood attacks.
The anti-attack udp-flood disable command disables defense against UDP flood attacks.
By default, defense against UDP flood attacks is enabled.
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.
