portStatsShow 2 portStatsShow Synopsis Description Displays port hardware statistics. portstatsshow [slotnumber/]portnumber portstatsshow [ge | ip | fcip ] [slotnumber/]geportnumber [ipaddress | tunnelnumber] Use this command to display port hardware statistics counters. Some counters are platform- or port-specific and display only on those platforms and ports. All statistics have a maximum 32-bit value of 4,294,967,295. The command output may include the following fields: stat_wtx The number of 4-byte words transmitted. stat_wrx The number of 4-byte words received. stat_ftx The number of frames transmitted. stat_frx The number of frames received. stat_c2_frx The number of class 2 frames received. stat_c3_frx The number of class 3 frames received. stat_lc_rx The number of link control frames received. stat_mc_rx The number of multicast frames received. stat_mc_to The number of multicast timeouts. stat_mc_tx The number of multicast frames transmitted. tim_rdy_pri The number of times that sending R_RDY or VC_RDY primitive signals was a higher priority than sending frames, due to diminishing credit reserves in the transmitter at the other end of the fiber. This parameter is sampled at intervals of 1.8 µs (microseconds), and the counter is incremented by 1 if the condition is true. 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.
