15.7.1.1 FC_MR-4 Statistics Window
The statistics window lists parameters at the line level. The Statistics window provides buttons to change
the statistical values shown. The Baseline button resets the displayed statistics values to zero. The
Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic
refresh occurs. The Statistics window also has a Clear button. The Clear button sets the values on the
card to zero. All counters on the card are cleared.

defines the FC_MR-4 card Statistics parameters.
Meaning
A time stamp indicating the last time statistics were reset.
Indicates whether the fibre channel link is receiving a valid
fibre channel signal (carrier) from the attached fibre channel
device; up means present, and down means not present.
A count of the number of fiber channel frames received
without errors.
A count of the number of bytes received without error for the
fiber channel payload.
A count of the number of transmitted fiber channel frames.
A count of the number of bytes transmitted from the fiber
channel frame.
A count of 10b errors received by the serial/deserializer
(serdes 8b/10b).
A count of the disparity errors received by serdes.
A count of the FC-MR software initiated link recovery
attempts toward the FC line side because of SONET
protection switches.
A count of the received fiber channel frames with errored
CRCs.
A count of the transmitted fiber channel frames with errored
CRCs.
A count of the received fiber channel frames < 36 bytes
including CRC, start of frame (SOF), and end of frame
(EOF).
A count of the received fiber channel frames > 2116 bytes of
the payload. Four bytes are allowed for supporting VSAN
tags sent.
A count of generic framing procedure (GFP) single bit errors
in the core header error check (CHEC).
A count of GFP multibit errors in CHEC.
A count of GFP invalid user payload identifier (UPI) field in
the type field.
A count of superblock CRC errors in the transparent GFP
frame.
