RFC2544 specifies an IP payload for the test packets. With timestamping, this
makes the minimum size of a test packet 66 bytes. If 64-byte packets are specified,
the unit will automatically adjust the size and place a warning message in the report.
If it is important to test with 64-byte packets, then the packet payload may be
specified as
IEEE803a (L2)
, which has a reduced overhead.

The throughput test may be skipped by setting this to
No
.
Note: Skipping the throughput test will mean that the latency test must be skipped
too, since it uses the results of the throughput test to set its rates.
14.2.6.3.3.2 Short Test Time
The short test time is fixed at 10 seconds.

The long test time can be set in the range 11 seconds to 1 hour, using one of the
standard time period entry methods (see section 13.3.1), or the long test can be
disabled by entering a value of 0.
