Parameter string: String of fill characters of a probe packet, in the range 1 to 200. It is case
sensitive.
Description Use the
data-fill command to configure the string of fill characters of a probe
packet.
Use the
undo data-fill command to restore the default.
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.
Example # Configure the string of fill characters of an ICMP-echo probe packet as abcd.
