132 Managing Ports
BB_CreditRecoveryFrameFailure Number of times more frames were lost during a credit recovery
period than the recovery process could resolve. This generates a Link
Reset to recover the credits.
BB_CreditRecoveryRRDYFailure Number of times more R_RDYs were lost during a credit recovery
period than the recovery process could resolve. This generates 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
may be discarded because a missing frame or an E_D_TOV timeout
is detected, a reject frame is received, or a frame is received 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 words transmitted 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 the N_Port that is preventing delivery
of this frame.
Flow Errors Number of times a frame is received when all the switch ports receive
buffers are full. The normal Fabric Login exchange of flow control
credit should prevent this from occurring. The frame is discarded.
FReject Number of frames, from devices, that have been rejected. Frames can
be rejected for many 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) 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.
