Description
Number of times more frames were lost during a credit recovery
period than the recovery process could resolve. This causes a Link
Reset to recover the credits.
Number of times more R_RDYs were lost during a credit recovery
period than the recovery process could resolve. This causes a Link
Reset to recover the credits.
Number of class 2 frames received by this port.
Number of class 2 frames transmitted by this port.
Number of class 2 words received by this port.
Number of class 2 words transmitted by this port.
Number of class 3 frames received by this port.
Number of class 3 frames transmitted by this port.
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.
Number of class 3 words received by this port.
Number of class 3 words transmitted by this port.
Number of invalid transmission words detected during decoding.
Decoding is from the 10-bit characters and special K characters.
Number of E_Port logins.
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.
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.
Number of frames, from devices, that have been rejected. Frames can
be rejected for any of a large number of reasons.
Number of invalid Cyclic Redundancy Check (CRC) frames detected.
Number of address identifier (S_ID, D_ID) errors. AL_PA equals
non-zero AL_PA found on F_Port.
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.
Number of F7, AL_PS LIPs, or AL_PD (vendor specific) resets,
performed.
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.
