Displaying Port Information
5-6 59097-02 B
S
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 time-
out, 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 decod-
ing. Decoding is from the 10-bit characters and special K char-
acters.
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 fail-
ure 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.
LIP(f7,f7) A loop initialization primitive frame used to acquire an AL_PA.
