15.7.1 FC_MR-4 Card Performance Monitoring Parameters
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.
Table 15-61 defines the FC_MR-4 card Statistics parameters.
Table 15-61 FC_MR-4 Statistics Parameters
Parameter Meaning
Time Last Cleared A time stamp indicating the last time statistics were reset.
Link Status 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.
Rx Frames A count of the number of fiber channel frames received
without errors.
Rx Bytes A count of the number of bytes received without error for the
fiber channel payload.
Tx Frames A count of the number of transmitted fiber channel frames.
Tx Bytes A count of the number of bytes transmitted from the fiber
channel frame.
8b/10b Errors A count of 10b errors received by the serial/deserializer
(serdes 8b/10b).
Encoding Disparity Errors A count of the disparity errors received by serdes.
Link Recoveries A count of the FC-MR software initiated link recovery
attempts toward the FC line side because of SONET
protection switches.
Rx Frames bad CRC A count of the received fiber channel frames with errored
CRCs.
Tx Frames bad CRC A count of the transmitted fiber channel frames with errored
CRCs.
Rx Undersized Frames A count of the received fiber channel frames < 36 bytes
including CRC, start of frame (SOF), and end of frame
(EOF).
Rx Oversized Frames A count of the received fiber channel frames > 2116 bytes of
the payload. Four bytes are allowed for supporting VSAN
tags sent.
GFP Rx HDR Single-bit Errors A count of generic framing procedure (GFP) single bit errors
in the core header error check (CHEC).
GFP Rx HDR Multi-bit Errors A count of GFP multibit errors in CHEC.
GGFP Rx Frames Invalid Type A count of GFP invalid user payload identifier (UPI) field in
the type field.
GFP Rx Superblk CRC Errors A count of superblock CRC errors in the transparent GFP
frame.
