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 microseconds, and the counter is incremented by 1 if the condition is true. 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 microseconds, and the counter is incremented if the condition is true. Each sample represents 2.5 microseconds 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 microseconds, indicating degraded performance. 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 microseconds (microseconds), and the counter is incremented if the condition is true. Each sample represents 2.5 microseconds 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 microseconds, indicating degraded performance (platform- and port-specific). The number of encoding errors inside frames. The number of frames with cyclic redundancy check (CRC) errors. The number of frames shorter than the minimum frame length. The number of frames longer than the maximum frame length. The number of frames with bad end-of-frame. The number of encoding error outside frames. The number of invalid ordered sets (platform- and port-specific). The number of Physical Coding Sublayer (PCS) block errors. This counter records encoding violations on 10 Gbps or 16 Gbps ports. This is applicable only on platforms that support 10 Gbps or 16 Gbps ports. The number of receive class 3 frames received at this port and discarded at the transmission port due to timeout (platform-and port-specific). The number of transmit class 3 frames discarded at the transmission port due to timeout (platform- and port-specific). The number of frames discarded because they cannot be routed. 846 Fabric OS Command Reference 53-1002746-01
