z
If the data field of a probe packet is smaller than the fill data, the system uses only the first part of
the character string to encapsulate the packet.
z
If the data field of a probe packet is larger than the fill data, the system fills the character string
cyclically to encapsulate the packet until it is full.
For example, when the fill data is
abcd
and the size of the data field of a probe packet is 3 byte,
abc
is
used to fill the packet. When the data field of a probe packet is 6 byte,
abcdab
is used to fill the packet.
z
In an ICMP echo test, the configured character string is used to fill the data field in an ICMP echo
message.
z
In a UDP echo test, because the first five bytes of the data field of a UDP packet have some
specific usage, the configured character string is used to fill the remaining bytes in the UDP
packet.
z
In a UDP jitter test, because the first 68 bytes of the data field of a UDP packet have some specific
usage, the configured character string is used to fill the remaining bytes in the UDP packet.
z
In a voice test, because the first 16 bytes of the data field of a UDP packet have some specific
usage, the configured character string is used to fill the remaining bytes in the UDP packet.
Examples
# Configure the string used to fill an ICMP echo probe packet as
abcd
.

Default Level
2: System level
Parameters
size
: Size of a probe packet in bytes, in the range 20 to 8100 for an ICMP echo or a UDP echo test, in
the range 68 to 8100 for a UDP jitter test and in the range 16 to 1500 for a voice test.
Description
Use the
data-size
command to configure the size of a probe packet to be sent.
Use the
undo data-size
command to restore the default.
