H3C MSR Series Command Reference

1066
With global ICMPv6 flood attack detection configured, the device is in attack detection state. When
the sending rate of ICMPv6 packets to an IPv6 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 ICMPv6 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] icmpv6-flood threshold 100

Parameters
policy-name: Specifies an attack defense policy by its name. The policy name is a case-insensitive
string of 1 to 31 characters. Valid characters include uppercase and lowercase letters, digits,
underscores (_), and hyphens (-).
ip: Specifies protected IPv4 addresses.
ipv6: Specifies protected IPv6 addresses.
statistics: Clears flood attack detection and prevention statistics.
Examples
# Clear flood attack detection and prevention statistics for protected IPv4 addresses in the attack
defense policy abc.
<Sysname> reset attack-defense policy abc flood protected ip statistics
# Clear flood attack detection and prevention statistics for protected IPv6 addresses in the attack
defense policy abc.
<Sysname> reset attack-defense policy abc flood protected ipv6 statistics
