Parameters
interval: Specifies the interval for tokens to arrive in the bucket. The value range is 0 to 2147483647
milliseconds. To disable the ICMPv6 rate limit, set the value to 0.
bucketsize: Specifies the maximum number of tokens allowed in the bucket. The value range is 1 to
200.
Usage guidelines
This command limits the rate at which ICMPv6 error messages are sent. Use this command to
prevent network congestion caused by excessive ICMPv6 error messages generated within a short
period. A token bucket algorithm is used with one token representing one ICMPv6 error message.
A token is placed in the bucket at intervals until the maximum number of tokens that the bucket can
hold is reached.
A token is removed from the bucket when an ICMPv6 error message is sent. When the bucket is
empty, ICMPv6 error messages are not sent until a new token is placed in the bucket.
Examples
# Set the bucket size to 40 tokens and the interval for tokens to arrive in the bucket to 200
milliseconds for ICMPv6 error messages.
