To create a TPerf data sink on VE_Port 16:
switch:admin> portcmd --tperf 16 -sink
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
To configure a Brocade FX8-24 blade as a TPerf data source (this example generates round-trip high,
medium, and low priority traffic with a fixed PDU size of 2084 bytes. The payload pattern is a jitter pattern
and the checksum is checked by the sink):
switch:admin> portcmd --tperf 16 -source \
-size 2048 -pattern 5
TPerf has been configured successfully for 16
TPerf is generating traffic on 16 priority: medium

To configure a TPerf source so it generates round-trip high and low priority traffic with a random PDU size
from 2048 to 10112 bytes (1 MSS) and with a payload pattern determined by previous settings saved in
memory:
switch: admin> portcmd --tperf 16 -source -high -low -random

****************************************************************
To configure a TPerf source to generate one-way low priority traffic with a random PDU size from 2048 to
4000 bytes and a payload pattern of ones.
