BB_CreditRecoveryRRDYF
ailure
Number of times more when R_RDYs were lost during a credit
recovery period than the recovery process could resolve. This
causes a Link Reset to recover the credits.
Class 2 Frames In Number of class 2 frames received by this port.
Class 2 Frames Out Number of class 2 frames transmitted by this port.
Class 2 Words In Number of class 2 words received by this port.
Class 2 Words Out Number of class 2 words transmitted by this port.
Class 3 Frames In Number of class 3 frames received by this port.
Class 3 Frames Out Number of class 3 frames transmitted by this port.
Class 3 Toss 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.
Class 3 Words In Number of class 3 words received by this port.
Class 3 Words Out Number of class 3 words transmitted by this port.
Decode Errors Number of invalid transmission words detected during
decoding. Decoding is from the 10-bit characters and special K
characters.
Ep Connects Number of E_Port logins.
FBusy 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.
Flow Errors Number of times a frame is received and all the switch ports
receive buffers are full. The normal Fabric Login exchange of
flow control credit should prevent this from occurring. The frame
will be discarded.
FReject Number of frames, from devices, that have been rejected. Frames
can be rejected for any of a large number of reasons.
Invalid CRC Number of invalid Cyclic Redundancy Check (CRC) frames
detected.
Invalid Destination
Address
Number of address identifier (S_ID, D_ID) errors. AL_PA equals
non-zero AL_PA found on F_Port.
Link Failures Number of optical link failures detected by this port. A link
failure is a loss of synchronization or by loss of signal while not
in the offline state. A loss of signal causes the switch to attempt
to re-establish the link. If the link is not re-established, a link
failure is counted. A link reset is performed after a link failure.
LIP (AL_PD,AL_PS) Number of F7, AL_PS LIPs, or AL_PD (vendor specific) resets,
performed.
