2 portStatsShow tim_txcrd_z The number of times that the port was unable to transmit frames because the transmit 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 µs (microseconds), and the counter is incremented if the condition is true. Each sample represents 2.5 µs of time with zero Tx BB Credit. An increment of this counter means that the frames could not be sent to the attached device for 2.5 µs, indicating degraded performance. tim_txcrd_z_vc The number of times that the port was unable to transmit frames because the transmit BB credit was zero for each of the port's 16 Virtual Channels (VC 0-15). The purpose of this statistic is to detect congestion or a device affected by latency. This parameter is sampled at intervals of 2.5 µs (microseconds), and the counter is incremented if the condition is true. Each sample represents 2.5 µs of time with zero Tx BB Credit. An increment of this counter means that the frames could not be send to the attached device for 2.5 µs, indicating degraded performance (platform- and port-specific). er_enc_in The number of encoding errors inside frames. er_crc The number of frames with cyclic redundancy check (CRC) errors. er_trunc The number of frames shorter than the minimum frame length. er_toolong The number of frames longer than the maximum frame length. er_bad_eof The number of frames with bad end-of-frame. er_enc_out The number of encoding error outside frames. er_bad_os The number of invalid ordered sets (platform- and port-specific). er_rx_c3_timeout The number of receive class 3 frames received at this port and discarded at the transmission port due to timeout (platform-and port-specific). er_tx_c3_timeout The number of transmit class 3 frames discarded at the transmission port due to timeout (platform- and port-specific). er_c3_dest_unreach The number of 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 The number of other discarded due to route lookup failures or other reasons. er_zone_discard The number of class 3 frames discarded due to zone mismatch. er_type1_miss The number of frames with FTB type 1 miss. er_type2_miss The number of frames with FTB type 2 miss. er_type6_miss The number of frames with FTB type 6 miss. er_zone_miss , er_lun_zone_miss The number of frames discarded due to hard zoning miss or LUN zoning miss. If Rx port hard zoning is enabled, frames will be discarded at the Rx port. If TX port hard zoning is enabled, frames will be discarded at the TX port. If both RX and TX port hard zoning is enabled, frames will be discarded at the RX port. (LUN zoning is currently not supported.) er_crc_good_eof The number of CRC errors with good end-of-frame (EOF) (platform- and port-specific). er_inv_arb The number of invalid arbitrated loops (ARBs). 790 Fabric OS Command Reference 53-1001764-01
