rst-flood threshold
Use rst-flood threshold to set the global threshold for triggering RST flood attack prevention.
Use undo rst-flood threshold to restore the default.
Syntax
rst-flood threshold threshold-value
undo rst-flood threshold
Default
The global threshold is 1000 for triggering RST flood attack prevention.
Views
Attack defense policy view
Predefined user roles
network-admin
Parameters
threshold-value: Specifies the threshold for triggering RST flood attack prevention. The value range is 1 to
1000000 in units of RST packets sent to an IP address per second.
Usage guidelines
The global threshold applies to RST flood attack detection for non-specific IP addresses.
Adjust the threshold according to the application scenarios. If the number of RST packets to a protected
server, such as an HTTP or FTP server, is normally large, set a large threshold. A small threshold might
affect the server services. For a network that is unstable or susceptible to attacks, set a small threshold.
Examples
# Set the global threshold to 100 for triggering RST flood attack prevention in attack defense policy
atk-policy-1.
