TXSTArt

Transmit one or more packets in background

TXSTArt

Shortest form: txsta.

Send packets like TX, but in a background thread, so the prompt returns at once. The arguments are the same as for TX, and so is the built-in help. Use TXCount to watch progress and TXSTOp to stop. Only one background transmission can run at a time; a second txstart prints <cmd>: Error: tx command running.

Like TX, txstart sends real traffic, for as long as it runs.

TXSTArt show

Print the state of the SDK’s TX module, instead of starting a transmission. The built-in help does not mention this form. show must be written in full. It works only while no background transmission is running. Read-only.

Parameters: <Count> [options]
  Transmit the specified number of packets, if the contents of the
  packets is important, they may be specified using options.
  Supported options are:

      TXUnit=<val>        - Transmit unit number
      PortBitMap=<pbmp>   - Specify port bitmap packet is sent to.
      UntagBitMap=<pbmp>  - Specify untag bitmap used for DMA.
      File=<filename>     - Load hex packet data from file and ignore
                            various other pattern parameters below.

      PerPortSrcMac=[0|1] - Associate specific (different) src macs
                            with each source port.
      SourceMac=<value>   - Source MAC address in packet
      SourceMacInc=<val>  - Source MAC increment
