Chapter 1. IBM Flex System FC3171 8 Gb SAN Switch - QLogic

The Statistics drop-down list is available on the Port Statistics data window, and
provides different ways to view detailed port information. Click the down arrow to
open the drop-down list, and select Absolute to view the total count of statistics
since the last switch or port reset. Select Rate to view the number of statistics
counted per second over the polling period. Select Baseline to view the total count
of statistics since the last time the baseline was set. When viewing baseline statistics,
click the Clear Baseline button to set the current baseline. The baseline will also be
set when the switch status changes from unreachable to reachable.
Table 21 describes the Port Statistics data window entries.

Description
The beginning of the period over which the statistics apply. The
start time for the Absolute view is not applicable. The start time
for the Rate view is the beginning of polling interval. The start
time for the Baseline view is the last time the baseline was set.
The last time the statistics were updated on the display.
Total time period from start time to end time.
Number of times the port entered the initialization state.
Number of times the port entered initialization and the initialization
failed. Increments count when port has a sync loss.
Number of frames that were truncated due to a loss of sync or
the frame didn't end with an EOF.
Number of times more frames were lost during a credit recovery
period than the recovery process could resolve. This value
causes a Link Reset to recover the credits.
Number of times more R_RDYs were lost during a credit recovery
period than the recovery process could resolve. This value
causes a Link Reset to recover the credits.
Number of class 2 frames received by this port.
Number of class 2 frames transmitted by this port.
Number of class 2 words received by this port.
Number of class 2 words transmitted by this port.
Number of class 3 frames received by this port.
Number of class 3 frames transmitted by this port.
Number of class 3 frames that were discarded by this port. A
frame can be discarded because of detection of a missing frame
(based on SEQ_CNT), detection of an E_D_TOV timeout, receiving
a reject frame, or receiving a frame on an offline port.
Number of class 3 words received by this port.
Number of class 3 words transmitted by this port.
Number of invalid transmission words detected during decoding.
Decoding is from the 10-bit characters and special K characters.
