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 is discarded.
Number of frames, from devices, that have been rejected. Frames can
be rejected for many 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
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.
