primitives need to be transmitted based on how many frames
were received. Credit is returned for frames that have a valid
SOF and at least one word of data following the SOF,
independent of the validity of the CRC.
Results - Strm Rslt (Stream Results) Screen
(Specifically for Fibre Channel SAN testing on the Packet tab)
The Stream Results screen displays the following statistics for the incoming stream:
Statistic Description
Selected Stream
Entry Displays the stream's WWN source and WWN destination
addresses.
Total Stream
Statistics Table
Provides transmit and receive statistics by Count and %BW.
Transmit Statistics:
•
Packets - Total number of Packets transmitted.
•
Bytes - Total number of Bytes transmitted.
•
BW - Percent of bandwidth currently being
transmitted.
Receive Statistics:
•
Packets - Total number of Packets received.
•
Bytes - Total number of Bytes received.
•
BW - Percent of bandwidth currently being received.
•
Loss - Current Packet Loss rate.
For loop backs with large latency, the Loss rate may
show greater than 0 while the test stream generation is
active, even if no packets are actually being lost
(dropped). This is due to the real-time RX packet count
being lower than the TX packet count, because of the
latency. If no packets were lost during the test, then
this value will drop to 0 when the test stream
generation is turned off.
Pass/Fail Test Provides User-Defined Acceptance Criteria:
