S
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.
LIP(f8,AL_PS) This LIP denotes a loop failure detected by the L_port identi-
fied by AL_PS.
LIP(f8,f7) A loop initialization primitive frame used to indicate that a Loop
Failure has been detected at its receiver and does not have a
valid AL_PA.
Login Count Number of device logins that have occurred on the switch.
Logout Count Number of device logouts that have occurred on the switch.
Loop Timeouts Number of loop timeouts.
Loss Of Sync Number of synchronization losses (>100 ms) detected by this
port. A loss of synchronization is detected by receipt of an
invalid transmission word.
Primitive Sequence
Errors
Number of bad primitives received by the port.
