Data-Size - HP 6125G Command Reference Manual

How the string is filled varies with test types:
• For ICMP echo tests, the string fills the whole data field of ICMP echo requests.
For UDP echo tests, the first five bytes of the data field of a UDP packet are for special purpose, so
•
the string fills the remaining part of data field.
For UDP jitter tests, the first 68 bytes of the data field of a UDP packet are for special purpose, so
•
the string fills the remaining part of the data field.
• For voice tests, the first 16 bytes of the data field of a UDP packet are for special purpose, so the
string fills the remaining part of the data field.
Examples
# Configure string abcd to be filled in the data field of an ICMP echo request.

Default level
2: System level
Parameters
size: Specifies the size of the data field in a probe packet in bytes. The value is in the range of 20 to 8100
for probe packets of ICMP echo or UDP echo tests, 68 to 8100 for probe packets of UDP jitter tests, and
16 to 1500 for probe packets of voice tests.
Description
Use data-size to configure the size of the data field in each ICMP echo request of the ICMP echo tests or
in each UDP packet of UDP echo, UDP jitter, or voice tests.
Use undo data-size to restore the default.
