Counts are reported on frames transmitted by the port (Tx) or on frames received by the port (Rx). The display contains one output line per port. Numeric values exceeding 999 are displayed in units of thousands (k), or millions (m) if indicated. Values for the following parameters are displayed: frames tx Number of frames transmitted (Tx). frames rx Number of frames received (Rx). enc in Number of encoding errors inside frames received (Rx). crc err Number of frames with CRC errors received (Rx). crc g_eof Number of frames with CRC errors with good EOF received (Rx). too shrt Number of frames shorter than minimum received (Rx). too long Number of frames longer than maximum received (Rx). bad eof Number of frames with bad end-of-frame delimiters received (Rx). enc out Number of encoding error outside of frames received (Rx). disc c3 Number of Class 3 frames discarded (Rx). This counter includes the sum of the following class 3 discard counters reported by the portStatsShow command: er_rx_c3_timeout, er_tx_c2_timeout, er_c2_dest_unreach, and er_other_disc. Refer to portStatsShow help for a description of these counters. link fail Number of link failures (LF1 or LF2 states) received (Rx). loss sync Number of times synchronization was lost (Rx). loss sig Number of times a loss of signal was received (increments whenever an SFP is removed) (Rx). frjt Number of transmitted frames rejected with F_RJT (Tx). fbsy Number of transmitted frames busied with F_BSY (Tx). c3-timeout tx The number of transmit class 3 frames discarded at the transmission port due to timeout (platform- and port-specific). 744 Fabric OS Command Reference 53-1002746-01
