
Unit: Select the result unit. Choices are:

Layer/Displayed Step/Mode
Layer (Throughput and Back-to-Back): Select the Layer that will be
used to compute the results. Choices are Layer 1,2,3, Layer 2,3 and
Layer 3. The default setting is Layer 1,2,3.

Layer 1,2,3 contains the Idle, Preamble, Start of Frame Delimiter,
MAC address, IP address, and data.

Layer 2,3 contains the MAC layer, IP layer, and data.

Layer 3 contains the IP layer, and data.
Displayed Step (Frame Loss only): Select the percentage of the
speed used for the test. Choices are 100% (or % of the maximum
speed) to 0% with increment set by the Test Granularity from the RFC
2544 Frame Loss tab. The default setting is 100% (or % of the
maximum speed). This is only available once the Frame Loss test is
started.
Mode (Latency test only): Select the propagation time mode. The
default setting is Store and Forward. Choices are:

Cut Through (Bit Latency): Cut Through allows the calculation of
the propagation time of a bit.

Store and Forward (Frame Latency): Store and Forward allows
the calculation of the propagation time of a frame.
