Table 4-14. portStatsShow Command Field Descriptions (continued) Field Description stat_ftx Number of frames transmitted from the port. stat_frx Number of frames received by the port. stat_c2_frx Number of Class 2 frames received. stat_c3_frx Number of Class 3 frames received. stat_lc_rx Number of link control frames received. stat_mc_rx Number of multicast frames received. stat_mc_to Number of timeouts reported for multicast frames. A single frame could cause this counter to increment if it timed out for each multiple destination. stat_mc_tx Number of multicast frames transmitted. tim_rdy_pri The amount of time (measured in proprietary ticks) that R_RDY transmission has higher priority than frame transmission. tim_txcrd_z Time that this port cannot transmit frames due to a transmit buffer-to-buffer credit of zero. er_enc_in Received data: the number of 8b/10b encoding errors that have occurred inside frame boundaries. This counter is generally a nonzero value, although occasional errors may occur on a normal link and give a zero result. (Minimum compliance with the link bit error rate specification on a link continuously receiving frames would cause approximately one error every 20 minutes.) er_crc Received frames: the number of CRC errors detected. er_trunc Received frames: the number of frames that were shorter than the minimum Fibre Channel frame size (for example, a header with no payload). er_toolong Received frames: the number of frames that were longer than the maximum Fibre Channel frame size (for example, a header with a 2,112-byte payload). er_bad_eof The number of frames received with a badly formed end-offrame. er_enc_out Receive link: the number of 8b/10b encoding errors recorded outside frame boundaries. This number may become nonzero during link initialization but indicates a problem if it increments faster than the allowed link-bit error rate (approximately once every 20 minutes). er_disc_c3 Receive link: the number of Class 3 frames discarded. Class 3 frames can be discarded due to timeouts or invalid/unreachable destinations. This quantity could increment at times during normal operation but might be used for diagnosing problems in some situations. 4-26 Dell PowerVault 51F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide
