Usage Guidelines

Usage Scenario

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

The device detects ICMP flood attack packets after defense against ICMP flood attacks is enabled. If the device detects ICMP flood attack packets, the device limits the rate of these ICMP flood attack packets to ensure that the device CPU works properly.

Precautions

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

Example

# Enable defense against ICMP flood attacks.
