31
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.
• In an ICMP echo test, the configured character string is used to fill the data field in an ICMP echo
message.
• 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.
• 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.
• 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.

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.
