6.6.2.1 Summary
The following results including the Start (ST) and Elapsed (ET) times are displayed:
Line Rate (Mbps):
Negotiated rate of the interface (10M, 100M, or 1000M). This value is always fixed since it depends on the maximum capacity of the link under
test, hence the test interface that is configured.
Framed Rate:
(P MAC/IP VLAN Tag + Type/ CRC) / (P Total Overhead) * Line Rate % (in Mbps).
Data Rate:
Payload / (P Total Overhead) * Line Rate %.
Utilization:
% of Line Rate. For example, if we transmit 100Mbps on a 1Gbps interface then the utilization value is 10% (or 100Mbps) of the total link capacity (or
Line Rate).
Number of bytes
Pause Frames:
Total number of transmitted and received ethernet pause flow-control frames.
