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.
The
milliseconds argument specifies the time interval between tokens
arriving in the bucket. The optional bucketsize argument is used to define the
maximum 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
bucketsize is 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.
Average Packets Per Second = (1000/
milliseconds ) * bucketsize .
To disable ICMP rate limiting, set the milliseconds argument to zero.
Example
The following example shows an interval of 50 milliseconds and a bucket size
of 20 tokens being configured for IPv6 ICMP error messages:
console(config)# ipv6 icmp error-interval 50 20
ipv6 nd dad attempts
Use the ipv6 nd dad attempts command in Interface Configuration mode to
configure the number of consecutive neighbor solicitation messages that are
sent on an interface while duplicate address detection is performed on the
Unicast IPv6 addresses of the interface.
To return the number of messages to the default value, use the no form of
this command.
