DataSize (DS)
For the loopback test, the data size specifies the data (frame payload) size in
bytes. The data size is the actual data that is transferred during any given pass of
the test.
DS <param value>
DataSize <param value>
The valid data sizes are as follows:
Read/write buffer test. The data size can be 8, 16, 32, 64, or 128 bytes.
The default value is 128 bytes.
Echo test. The data size can be 8, 16, 32, 64, 128, 256, 512, 1024, or 2048.
The default size is 512.
Loopback test (Windows, Solaris, and Macintosh systems). The data
size can be 8, 16, 32, 64, 128, 256, 512, 1024, or 2048. The default value is
512 bytes.
Loopback test (Linux systems). The data size can be 8, 16, 32, 64, 128,
256, 512, 1024, 2048, 4096, 8192, 16384, 32768, or 65535. The default
value is 512 bytes.
TestCount (TC)
The test count specifies the number of loopback tests:
TC <param value>
TestCount <param value>
For a read/write buffer test, the number of tests run must be in the range of
0–10000.
For a loopback test, the number of tests run must be in the range of 0–65535.
For both tests, a value of 0 indicates that the test runs continuously (it stops
when you press
ENTER
). The default number of tests run is 500.
TestIncrement (TI)
The test increment for the loopback test is either of the following:
TI <param value>
TestIncrement <param value>
For a read/write buffer test, the test increment must be in the range of 1–10000.
For a loopback test, the test increment must be in the range of 1–65535.
If the number of tests is continuous (see “TestCount (TC)” on page 4-23), the test
increment is automatically set to one of the following:
