Description Configure ICMPv6 rate limiting for IPv6 to protect against denial-of-service (DoS) attacks.
Syntax [no] icmpv6-rate-limit normal-rate lockup max-rate lockup-time
Mode Configuration mode
Usage This command configures ICMPv6 rate limiting globally for all traffic to or through the ACOS device. To configure ICMPv6 rate limiting on individual Ethernet interfaces, see the icmpv6-rate-limit command in the “Config Commands: Interface” chapter in the Network Configuration Guide. To configure it in a virtual server template, see . If you configure ICMPv6 rate limiting filters at more than one of these levels, all filters are applicable.
Specifying a maximum rate (lockup rate) and lockup time is optional. If you do not specify them, lockup does not occur.
Log messages are generated only if the lockup option is used and lockup occurs. Otherwise, the ICMPv6 rate-limiting counters are still incremented but log messages are not generated.
