ip icmp error-interval
Use ip icmp error-interval to set the bucket size and the interval for tokens to arrive in the bucket for
ICMP error messages.
Use undo ip icmp error-interval to restore the default.
Syntax
ip icmp error-interval interval [ bucketsize ]
undo ip icmp error-interval
Default
The bucket allows a maximum of 10 tokens, and a token is placed in the bucket every 100
milliseconds.

Parameters
interval: Specifies the interval for tokens to arrive in the bucket. The value range is 0 to 2147483647
milliseconds. To disable the ICMP 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 ICMP error messages are sent. Use this command to avoid
sending excessive ICMP error messages within a short period that might cause network congestion.
A token bucket algorithm is used with one token representing one ICMP 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 ICMP error message is sent. When the bucket is empty,
ICMP 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 ICMP error messages.
