TTCP certainly works with 3600s. But it requires Enterprise IOS. I'm not sure
if PLUS supports it.
Chuck,
See: http://www.cisco.com/warp/public/471/ttcp.html for the correct syntax. No
te that you can download PC/Unix based clients as well (the above URL has a lin
k for it). While TTCP is a bit dated, it's a good quick&dirty test mechanism.
Also, if your BANDWIDTH*DELAY is 10^^6 (so for your T3, 25 ms or so will result
in 10^^6 BW*DELAY product) you CANNOT fill the pipe with host-to-host TCP traf
fic.
Down load the PC/Unix client and try it with UDP. Since there are no concepts
of windowing for UDP, you will most likely get a bump in throughput.
All of this assumes you have the proper working CSU etc. (clocking, framing, e
tc.)
Does your T3 links have 25+ms round-trip delays?
I'll see if I can sanitize my post-mortem so that I can send it to you (if you
want it)
