The Port Statistics data window displays statistics about port performance. Select one or more ports in the
faceplate display that you want to view statistics. Click the Port Stats data window tab to open the Port
Statistics window.
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. 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. Click Clear Baseline to set the current baseline when
viewing baseline statistics. The baseline will also be set when the switch status changes from unreachable
to reachable.

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 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.
Number of E_Port logins
Number of class 2 and class 3 fabric busy (F_BSY) frames
generated by this port in response to incoming frames. This
usually indicates a busy condition on the fabric or N_port that is
preventing delivery of this frame.
