Default
Global ICMPv6 flood attack detection is disabled.

Usage guidelines
The global ICMPv6 flood attack detection applies to all IPv6 addresses except for those specified by
the icmpv6-flood detect ipv6 command. The global detection uses the global trigger threshold set
by the icmpv6-flood threshold command and global actions specified by the icmpv6-flood action
command.
Examples
# Enable global ICMPv6 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] icmpv6-flood detect non-specific
Related commands
icmpv6-flood action
icmpv6-flood detect ipv6
icmpv6-flood threshold
icmpv6-flood threshold
Use icmpv6-flood threshold to set the global threshold for triggering ICMPv6 flood attack
prevention.
Use undo icmpv6-flood threshold to restore the default.
Syntax
icmpv6-flood threshold threshold-value
undo icmpv6-flood threshold
Default
The global threshold is 1000 for triggering ICMPv6 flood attack prevention.

Parameters
threshold-value: Specifies the threshold value. The value range is 1 to 1000000 in units of ICMPv6
packets sent to an IP address per second.
Usage guidelines
The global threshold applies to global ICMPv6 flood attack detection. Adjust the threshold according
to the application scenarios. If the number of ICMPv6 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.
