Appendix A—Using a Windows PC as a TTCP End Device
a. Download the TTCP for Windows ttcpw program from the link provided at
http://www.cisco.com/en/US/tech/tk801/tk36/technologies_tech_note09186a0080094694.shtml.
b. Expand the ZIP file in a folder to access the .exe and readme files.
c. Start the ttcpw program on the PC (in a DOS window), running as a receiver. Refer to the Readme
file provided with the windows TTCP software for the appropriate syntax. An example is provided
here.
C:\Cisco\TTCP>ttcpw -r -s ttcp-r: buflen=8192, nbuf=2048, align=16364/0,
port=5001 tcp ttcp-r: socket
d. Start the ttcp program on DLS2 running as a transmitter and specify the target IP address of the PC.
DLS2#ttcp
transmit or receive [receive]: transmit
Target IP address: 10.1.80.254
calculate checksum during buffer write [y]:
perform tcp half close [n]:
send buflen [32768]:
send nbuf [2048]:
bufalign [16384]:
bufoffset [0]:
port [5001]:
sinkmode [y]:

show tcp information at end [n]:
e. When the transfer completes, you should see the results on the transmitter and receiver. The
following output is from DLS2, the transmitter.
ttcp-t: buflen=32768, nbuf=2048, align=16384/0, port=5001 tcp ->
10.1.80.254
