WAN performance analysis tools 4 -time Specifies the duration of the Tperf traffic flow in seconds. If a 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 1 and the size of the send request, as set by -size. -crc Specifies cyclic redundancy check (CRC) to be performed on the payload. -pattern Specifies the test data pattern for the payload as one of the following values: 0 - No pattern is specified. Tperf applies whatever is already set or in memory. This is the default value. 1 - All zeros 2 - All ones 3 - Incrementing byte 4 - Random 5 - Jitter -size Specifies the PDU size to use (not including headers). This is also sets the maximum size if the -random option is specified.The valid range is 4 to 10112. The default is 10112, which is equivalent to the maximum segment size (MSS). -interval Specifies the interval at which the statistics display is refreshed, in seconds. The default is 30 seconds. The following example creates a Tperf data sink and a Tperf data source on VE_port 16. switch:admin> portcmd --tperf 16 -sink -interval 15 TPerf has been configured successfully for 16 TPerf is servicing requests on 16 priority: high TPerf is servicing requests on 16 priority: medium TPerf is servicing requests on 16 priority: low Tperf data source can now be started Tunnel ID: 16 High Priority Medium Priority Low Priority bytes tx 1898680 1579600 1233240 bytes rx 481884984 400902480 312996312 PDUs tx 47467 39490 30831 PDUs rx 47467 39490 30831 bad CRC headers rx 0 0 0 bad CRC payloads rx 0 0 0 out of seq PDUs rx 0 0 0 flow control count 0 0 0 packet loss (%) 100.0000 100.0000 100.0000 bytes/second 32319450 26806951 20869073 last rtt N/A N/A N/A Fabric OS FCIP Administrator's Guide 73 53-1001766-01
