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
TPerf is servicing requests on 16
TPerf is servicing requests on 16
Tperf data source can now be started

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.
Generates traffic in one direction only. The default is round-trip.
Specifies a random protocol data unit (PDU) size between 1 and the size of
the send request, as set by -size.
Specifies cyclic redundancy check (CRC) to be performed on the payload.
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
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).
Specifies the interval at which the statistics display is refreshed, in seconds.
The default is 30 seconds.
