tim_txcrd_z The number of times that the port was unable to transmit frames because
the transmit buffer-to-buffer (BB) credit was zero. The purpose of this
statistic is to detect congestion or a device affected by latency. This
parameter is sampled at intervals of 2.5 microseconds, and the counter is
incremented if the condition is true. Each sample represents
2.5 microseconds of time with 0 Tx BB Credit. An increment of this counter
means that the frames could not be sent to the attached device for
2.5 microseconds, indicating degraded performance.
Error statistics:
er_enc_in Encoding errors inside frames.
er_crc Frames with cyclic redundancy check (CRC) errors.
er_trunc Frames shorter than the minimum frame length.
er_toolong Frames longer than the maximum frame length.
er_bad_eof Frames with bad end-of-frame.
er_enc_out Encoding error outside frames.
er_bad_os Invalid ordered sets (platform-specific and port-specific).
er_rx_c3_timeout Receive class 3 frames received at this port and discarded at the
transmission port due to timeout (platform-specific and port-specific).
er_tx_c3_timeout Transmit class 3 frames discarded at the transmission port due to timeout
(platform-specific and port-specific).
er_c3_dest_unreach Class 3 frames discarded because the transmit port, although it is
determined, cannot send the frame at the moment when the error occurs.
er_other_discard Other discards due to route lookup failures or other reasons.
er_type1_miss FCR frames with transmit errors.
er_type2_miss Frames with routing errors.
er_type6_miss FCR frames with receive errors.
er_zone_miss Frames discarded due to hard zoning miss. Hardware zoning enforcement
is not supported currently.
er_lun_zone_miss Frames discarded due to zoning miss. LUN zoning is not supported
currently.
er_crc_good_eof CRC errors with good end-of-frame (EOF).
er_inv_arb Invalid ARBs.
Port error information:
Loss_of_sync Link synchronization errors.
Loss_of_sig Link loss-of-signal errors.
Frjt Transmitted frames rejected.
Fbsy Transmitted frames busied.
Buffer information:
Lx Mode L0—Link not in long-distance mode.
