Use undo icmpv6-flood threshold to restore the default.

icmpv6-flood threshold threshold-value
undo icmpv6-flood threshold

Parameters
threshold-value: Specifies the threshold for triggering ICMPv6 flood attack prevention. 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 ICMPv6 flood attack detection for non-specific IPv6 addresses.
Adjust the threshold according to the application scenarios. If the number of ICMPv6 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.
