the peer or reflector.

The Name button allows you to assign a custom name to the
test. See also: “Name” on page 105 .
5
Target Rate - This is the requested rate of upstream
traffic (from the source analyzer to the peer). Valid rates are
from 100 Kbps to 1 Gbps. If the actual rate is less than 99% of
the requested rate, the test will fail.
Target Rate - This is the requested rate of downstream
traffic (from the peer to the source analyzer). Valid rates are
from 100 Kbps to 1 Gbps. If the actual rate is less than 99% of
the requested rate, the test will fail.
Note
The above description applies when using a peer.
When using a reflector, upstream and downstream
traffic are not individually measured. Results are
based on roundtrip traffic, and only one rate can be
specified.
6
Loss Limit: is the percentage of frames that can be lost. If this
value is exceeded, the test will fail.
7
Duration is the length of time the test will run. You can run a
quick one second test or up to a full minute of testing.
8
Frame Size is the size of the frames that the OneTouch
analyzer will exchange with the endpoint. The header is
included in the frame size.
Sweep performs an RFC 2544
sweep test. The test runs for the specified duration at each
frame size: 64 B, 128 B, 256 B, 512 B, 1024 B, 1280 B, and
1518 B. Results can be viewed in tabular or graphical format.
See “Results” on
page 139.

The DSCP (Differentiated Services Code Point) control allows
for verification of higher quality of service (QoS) for
applications such as VoWiFi. Using the DSCP control, you can
specify a priority for the generated traffic by changing its
classification. This is a six-bit field. The default value of zero
specifies “best effort.”
