All,

I am configuring a small metro area network and am looking for a
command/commands or tools that will allow me to simulate traffic/test
available & used bandwidth. I have MRTG configured to graph results but
wanted something to create the traffic with. (No I am not planning a DOS
attack)

Devices:

Cisco
2948G
6509 (layer 3)

and 4 pair of licensed Wireless 100 MB Winnet Radios----------> 100BaseT
interfaces

Circuits are ILEC DS3's with the Winnet links as backups.

Any Ideas/comments are appreciated.

solarwinds.net makes a program called Wan Killer that will generate traffic
from a windows workstation to the UDP or TCP port of you choice. I think
their web site will let you download it for a 30 day trial

But to REALLY stress your network, a measily Windows PC will not do it.
It CANNOT saturate a gig link, and it can barely saturate a 100Mps link.

If you need it, smartbits will do it.

Hi

Not "the" perfect tool, but if you want to create some (not total,
abolutely wire-melting, but measurable) traffic, try
TTCP - it's on some IOSes (just type TTCP on a router to be sure) and also
available for Unix/Windows (Java).

Have fun

Nahshon,

Sniffer, http://www.sniffer.com/ , has a feature that lets you capture
actual traffic & regenerate it. Helpful if you need to simulate typical
traffic. You'd probably want to run it from a few PCs simultaneously.

Hope this helps,
Ian

Also look at www.networkinstruments.com
You can get about 6 copies of that software for what one copy of NIA's
sniffer pro costs and it does the same thing.

Also have a look at Chevin TeVista software they do a 'LAN stress
tester'. Not sure what the price is though?
