Usage guidelines
The global HTTP flood attack detection applies to all IP addresses except for those specified by the
http-flood detect command. The global detection uses the global trigger threshold set by the
http-flood threshold command and global actions specified by the http-flood action command.
Examples
# Enable global HTTP flood attack detection in the attack defense policy atk-policy-1.
<Sysname> system-view
[Sysname] attack-defense policy atk-policy-1
[Sysname-attack-defense-policy-atk-policy-1] dns-flood detect non-specific

Parameters
port-list: Specifies a space-separated list of up to 65535 port number items. Each item specifies a
port by its port number or a range of ports in the form of start-port-number to end-port-number. The
end-port-number cannot be smaller than the start-port-number.
Usage guidelines
The device detects only HTTP packets destined for the specified ports.
The global ports apply to global HTTP flood attack detection and IP address-specific HTTP flood
attack detection with no port specified.
Examples
# Specify the ports 80 and 8080 as the global ports to be protected against HTTP flood attacks in the
attack the defense policy atk-policy-1.
<Sysname> system-view
[Sysname] attack-defense policy atk-policy-1
[Sysname-attack-defense-policy-atk-policy-1] http-flood port 80 8080
