NQA commands

data-fill

Use data-fill to configure the string to be filled in the payload of each probe packet.
Use undo data-fill to restore the default.
Syntax
data-fill string
undo data-fill
Default
The string is the hexadecimal number 00010203040506070809.
Views
ICMP echo operation view, UDP echo operation view
Predefined user roles
network-admin
Parameters
string: Specifies a case-sensitive string of 1 to 200 characters.
Usage guidelines
If the payload length is smaller than the string length, only the first part of the string is filled. For example,
if you configure the string as abcd and the payload size as 3 bytes, abc is filled.
If the payload length is greater than the string length, the system fills the payload with the string cyclically
until the payload is full. For example, if you configure the string as abcd and the payload size as 6 bytes,
abcdab is filled.
How the string is filled varies with operation types:
For the ICMP echo operation, the string fills the whole payload of an ICMP echo request.
•
• For the UDP echo operation, the first five bytes of the payload of a UDP packet are for special
purpose, so the string fills the remaining part of payload.
Examples
# Configure string abcd to be filled in the payload of an ICMP echo request.
<Sysname> system-view
[Sysname] nqa entry admin test
[Sysname-nqa-admin-test] type icmp-echo
[Sysname-nqa-admin-test-icmp-echo] data-fill abcd

data-size

Use data-size to configure the size of the payload in each ICMP echo request of the ICMP echo, or in
each UDP packet of the UDP echo.
