portCmd 754 The following optional arguments are ignored on the data sink, because it services all requests from the data source: -high, -medium, -low, -unidirectional, -random, -pattern, and -size. When -source is specified, TPerf generates traffic until it is interrupted by user intervention (Ctrl + c) or, if a value for duration is specified with the -t option, until the process completes the set time frame. The TPerf module on the remote host will immediately begin generating traffic; it is therefore imperative that the data sink has been started on the opposing switch before the data source is started on the local switch. The following arguments are optional: -high Generates high priority traffic. -medium Generates medium priority traffic. -low Generates low priority traffic. If no traffic priority is specified only medium priority traffic is generated. -time duration Specifies the duration of the TPerf traffic flow in seconds. If a value for duration is not specified, the process continues to run until it is terminated with Ctrl + C. -unidirectional Generates traffic in one direction only. The default is round-trip. -random Specifies a random protocol data unit (PDU) size between 2048 and the size of the send request. Refer to -size below. -pattern pattern Specifies the test data pattern for the payload as one of the following values: 0 | notspecified No pattern is specified. TPerf applies whatever is already set or in memory. This is the default value. 1 | allzeros The specified pattern is "all zeros". 2 | allones The specified pattern is "all ones". 3 | incrementingbyte The specified pattern is "incrementing byte". 4 | random The specified pattern is "random". 5 | jitter The specified pattern is "jitter".
