Icmpv6-Flood Action - HP FlexNetwork 7500 Series Command Reference Manual

The global threshold applies to global ICMP flood attack detection. Adjust the threshold according to
the application scenarios. If the number of ICMP packets sent 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 ICMP flood attack prevention in attack defense policy
atk-policy-1.
<Sysname> system-view
[Sysname] attack-defense policy atk-policy-1
