Hello!

I have posted earlier a problem, I am having in my network, where I cannot figure out, where the problem is, so my network is being still unstable. Here you can read about the problem with network: http://www.experts-exchange.com/Networking/Protocols/Q_24304808.html

I am looking for the software, app, which could send/broadcast raw packets on net (L2 level), where is no IP, to see if there is problem with one specific switch on the network. Is there any available? If there is no such software for L2 level broadcast, maybe you could suggest ony L3 level broadcasting software (TCP/UDP/ICMP/RAW)?

Thanks.

There are low-cost packet generators available -- jst do a google search for "Packet Generator" and you'll find several.  Here's one link that has a few to play with:

Some you'll find are Linux only, but others will work on Windows.

The only one I've used was the one built into Network General Sniffer software, and you can use it to craft any network packet and send it multiple times.

If your original problem is still an issue, I would recommend setting up a SPAN port on the Cisco and capturing the resulting traffic with Wireshark (www.wireshark.org), then look through the dump, looking for the "interesting" stuff...
