Description
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.
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.
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 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.
Number of class 3 words received by this port.
Number of class 3 words transmitted by this port.
Number of invalid words transmitted 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 the
N_port that is preventing delivery of this frame.
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 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.
