milliseconds

—Time interval between tokens being placed in the bucket.

Each token represents a single ICMP error message. The acceptable range

is from 0 to 2147483647. A value of 0 disables ICMP rate limiting.

—Maximum number of tokens stored in the bucket. The

acceptable range is from 1 to 200.

Default Configuration

The default interval is 100ms and the default bucketsize is 10 i.e. 100 ICMP error

messages per second.

Command Mode

User Guidelines

Use this command to limit the rate at which IPv6 ICMP error messages are sent. A

token bucket algorithm is used with one token representing one IPv6 ICMP error

message. Tokens are placed in the virtual bucket at a specified interval until the

maximum number of tokens allowed in the bucket is reached.

milliseconds

argument specifies the time interval between tokens arriving in

the bucket. The optional

number of tokens allowed in the bucket. Tokens are removed from the bucket

when IPv6 ICMP error messages are sent, which means that if the

set to 20, a rapid succession of 20 IPv6 ICMP error messages can be sent. When

the bucket is empty of tokens, IPv6 ICMP error messages are not sent until a new

token is placed in the bucket.
