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)?
