Parameters
milliseconds: Sets the interval between tokens arriving in the bucket. The value range is 0 to 2147483647
milliseconds, and the default is 100 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,
and the default is 10.
Usage guidelines
To avoid sending excessive ICMP error messages within a short period that might cause network
congestion, you can use the command to limit the rate at which ICMP error messages are sent. A token
bucket algorithm is used with one token representing one ICMP error message. Tokens are placed in the
bucket at a specific interval until the maximum number of tokens that the bucket can hold is reached.
Tokens are removed from the bucket when ICMP error messages are sent. When the bucket is empty,
ICMP error messages are not sent until a new token is placed in the bucket.
Examples
# Configure an interval of 200 milliseconds and bucket size of 40 tokens for ICMP error messages.
<Sysname> system-view
[Sysname] ip icmp error-interval 200 40
ip icmp source
Use ip icmp source to enable specifying the source address for outgoing ICMP packets.
Use undo ip icmp source to restore the default.
Syntax
ip icmp source [ vpn-instance vpn-instance-name ] ip-address
undo ip icmp source [ vpn-instance vpn-instance-name ]
Default
The device uses the IP address of the sending interface as the source IP address for outgoing ICMP
packets.
