User Manual
Target Rate - 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 - 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.
The above description applies when using a peer.
When using a reflector, upstream and downstream
traffic are not individually measured. Results are
based on round-trip traffic, and only one rate can be
specified.
Duration - the length of time the test will run. You can run a quick
one-second test or up to a full minute of testing.
Frame Size - the size of the frames that the 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
Loss Limit - the percentage of frames that can be lost. If this value
is exceeded, the test will fail.
DSCP (Differentiated Services Code Point) - allows you to 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."This configuration parameter lets you verify higher
quality of service (QoS) for applications such as VoWiFi.
Port - specifies the UDP port for the test's control connection. The
same port must be specified on the peer endpoint. The next two
higher port numbers are also used for the test. See "How it
Works," below.
