@Anonymous(last): You couldn't generate significant traffic load using Tcl on the router. Furthermore, baseline Tcl (as ported to IOS) supports only TCP sessions, you need host-specific binary libraries to send UDP packets or raw IP packets.

Something that would be VERY interesting would be if someone figured out TCL for it....Then you could run it on any cisco router.

A TCL based packet generation tool is available and is called netexpect. As the name suggests it's basically expect for packets. I.e. you send a packet and expect a response.

I never got a documentation marked "confidential" saying TAC is overloaded :))

Thanks for the Scapy link, looks like a really useful tool. We wanted to use PCs for packet generators in remote labs for quite a while, but somehow never found time to investigate the tools out there. Any idea what a suitable replacement for callgen might be?

On the negative side, looks like I'll have yet another scripting language to learn. I though PERL, ASP, PHP and Tcl would be enough ... but scapy is written in Python :((

"always overloaded TAC" : you just broke the TAC NDA !! :-)

There are free and open alternatives to our internal tools. Just use scapy instead of pagent/tgn for example.
