portCmd 2 -c L2 Class-of-Service Specifies Class of Service/Priority, as defined by the IEEE 802.1p specification. Values must be in the range of 0 to 7. The default value is 0. This operand is optional with the -v option. --tperf Determines the path characteristics to a remote host or tunnel destination The -tperf option requires two separate Brocade FX-24 blades to function. One blade plays the role of a data sink and the other blade plays the role of the data source. TPerf also requires that you define a tunnel as a TPerf tunnel. Refer to portCfg fciptunnel for more information. -sink | -source Designates the switch to function either as a data sink or a data source. This operand is required. When -sink is specified, TPerf begins to respond to traffic sent by the switch acting as the data source. The process continues to run until it is either terminated 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 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. -time duration If no traffic priority is specified, high, medium, and low priority traffic is generated. 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. -loop Reissues a send request as fast as possible after completion of the previous send request. -random Specifies a random protocol data unit (PDU) size between 1 and the size of the send request. Refer to -size below. -crc Specifies cyclic redundancy check (CRC) to be performed on the payload. Fabric OS Command Reference 695 53-1001764-02
