Icmp-Flood Action - HP FlexNetwork MSR Series Command Reference Manual

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.
With global HTTP flood attack detection configured, the device is in attack detection state. When the
sending rate of HTTP packets to an IP address reaches the threshold, the device enters prevention
state and takes the specified actions. When the rate is below the silence threshold (three-fourths of
the threshold), the device returns to the attack detection state.
Examples
# Set the global threshold to 100 for triggering HTTP flood attack prevention 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] http-flood threshold 100
