string: String of fill characters of a probe packet, in the range 1 to 200. It is case
sensitive.
Use the command to configure the string of fill characters of a probe

packet.

undo data-fill
By default, the string of fill characters of a probe packet is the string
corresponding to the ASCII code 00 to 09.
If the probe packet is smaller than the fill data, the system uses only the first
■
part of the character string to encapsulate the packet.
If the 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 a probe packet is 3 byte,
abc is used to fill the packet. When the probe size is 6 byte, abcdab is used to fill
the packet.
Because the first five bytes of a probe packet in a UDP-echo test have some
■
specific usage, the configured character string is used to fill the remaining bytes
in the probe packet.
Because the first 68 bytes of a probe packet in UDP-jitter test have some
■
specific usage, the configured character string is used to fill the remaining bytes
in the probe packet.
# Configure the string of fill characters of an ICMP-echo probe packet as abcd.
