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.
LIP(f7,AL_PS)
This LIP is used to reinitialize the loop. An L_port, identified by
AL_PS, may have noticed a performance degradation and is
trying to restore the loop.
