portPerfShow 2 portPerfShow Displays port throughput performance in bytes, kilobytes, or megabytes. Synopsis portperfshow [interval] Description Use this command to display throughput information for all ports on the switch. Data displays 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, until Enter, Ctrl-c, or Ctrl-d is pressed. This command displays 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 execution of this command is subject to Admin Domain restrictions that may be in place. Operands This command has the following operand: interval Specify the interval, in seconds, between each sample. Default is one second. This operand is optional. When fastwrite or tape pipelining is enabled, the portperfshow VE link output is different. The acceleration entity (fastwrite or tape pipelining) will respond (sending XFER_RDY and status) well ahead of the actual device's response to the host. The host will send the data and that data will be stored near to the device and will be 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, portperfshow output on VE link may not match the output on the device port.
