Parameters
size: Specifies the payload size. Available value ranges include:
• 20 to 65507 bytes for the ICMP echo, UDP echo, or UDP tracert operation.
• 68 to 65507 bytes for the UDP jitter or path jitter operation.
• 16 to 65507 bytes for the voice operation.
Usage guidelines
In ICMP echo and path jitter operations, the command sets the payload size for each ICMP echo
request.
In UDP echo, UDP jitter, UDP tracert, and voice operations, the command sets the payload size for
each UDP packet.
Examples
# Set the payload size to 80 bytes for each ICMP echo request.
