Usage guidelines
Enable HTTP client verification on the interface connected to the external network. This feature
protects internal servers against HTTP flood attacks.
For the HTTP client verification to collaborate with HTTP flood attack prevention, specify
client-verify as the HTTP flood attack prevention action. During collaboration, the device adds the
victim IP address to the protected IP list and verifies the untrusted sources if it detects an HTTP flood
attack. You can use the display client-verify http protected ip command to display the protected
IP list for HTTP client verification.
Examples
# Enable HTTP client verification on interface GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] client-verify http enable
