Table 18 Port Statistics data window fields (Continued) Field Description BB_CreditRecoveryRRDYFail Number of times more R_RDYs were lost during a credit recovery period ure 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 Class 3 Frames In Number of class 2 words transmitted by this port. 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 Decode Errors 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. Ep Connects Number of E_Port logins. FBusy Flow Errors 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. 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 Link Failures 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. LIP(AL_PD,AL_PS) Number of F7, AL_PS LIPs, or AL_PD (vendor specific) resets performed. LIP(F7,AL_PS) LIP(F7,F7) 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. A loop initialization primitive frame used to acquire an AL_PA. LIP(F8,AL_PS) Denotes a loop failure detected by the L_port identified 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.
