portPerfShow 2 portPerfShow Synopsis Displays port throughput performance. portperfshow [interval] Description Use this command to display throughput information for all ports on the switch. Output includes the number of bytes received plus the number of bytes transmitted per interval. Throughput values are displayed as either bytes, kilobytes (k), megabytes (m), or gigabytes (g). Values are always rounded down. The data is displayed in 8 or 16 columns, one column per port plus one column that displays the total for these ports. Results display every second or over the specified interval. Enter, Ctrl-c, or Ctrl-d to exit the display. Note The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for details. Operands This command has the following operand: interval Specifies the interval, in seconds, between each sample. Default is one second. This operand is optional. When Fastwrite or Tape Piplelining is enabled, the portPerfShow VE link output is different. The acceleration entity (Fastwrite or Tape Piplelining) responds by sending XFER_RDY and status well ahead of the actual device's response to the host. The host sends data which is stored near the device and is delivered to the device only when the device is ready. So the data may be stored near the target for some brief period of time. In this case, the portPerfShow output on the VE link may not match the output on the device port.
