To configure rate limit for ICMP error messages:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Set the interval and bucket
size for ICMP error
messages
ip icmp error-interval
milliseconds [ bucketsize ]
By default, the bucket allows a maximum
of 10 tokens, and tokens are placed in
the bucket at the interval of 100
milliseconds.
To disable the ICMP rate limit, set the
interval to 0 milliseconds.
Specifying the source address for ICMP packets
Perform this task to specify the source IP address for outgoing ping echo request and ICMP error
messages. H3C recommends that you specify the IP address of the loopback interface as the source IP
address. This feature helps users to locate the sending device easily.
If you specify an IP address in the ping command, ping echo requests use the specified address as the
source IP address rather than the IP address specified by the ip icmp source command.
To specify the source IP address for ICMP packets:
Step Command

N/A
2.
Specify the source address
for outgoing ICMP
packets.
ip icmp source [ vpn-instance
vpn-instance-name ] ip-address
By default, the device uses the IP address
of the sending interface as the source IP
address for outgoing ICMP packets.
