Hi I hit a similar problem with the cisco mac controls . I had to use an ethernet hub (1000 mbps ) / direct cat 6 cable (1g) in the end to achieve the throughput
The switch was dumping / blocking 80% of the generated traffic Regards Nigel -----Original Message----- From: Aaron Turner <synfina...@gmail.com> Sent: 07 July 2020 23:10 To: Main forum for tcpreplay <tcpreplay-users@lists.sourceforge.net> Subject: Re: [Tcpreplay-users] TCPReplay vis Managed Switch Sounds like your switch isn't forwarding the packets because it doesn't believe they should be delivered to the port your listening server is on because the destination MAC address isn't on that port. Hence, you'd need to rewrite the packets (tcprewrite) to change the dst mac. -- Aaron Turner https://synfin.net/ Twitter: @synfinatic My father once told me that respect for the truth comes close to being the basis for all morality. "Something cannot emerge from nothing," he said. This is profound thinking if you understand how unstable "the truth" can be. -- Frank Herbert, Dune On Tue, Jul 7, 2020 at 11:56 AM Prashantha Rao <prashanthara...@gmail.com> wrote: > > Hello Support, > > I am using TCPReplay along with other traffic to increase the network load. To make this happen I need to use a managed switch to union the Ethernet frames. I am facing a problem. The TCPReplay communication is not reaching the destination. But if the TCPReplay Computer is connected to Destination with a direct cable it works perfect with out any loss. Please let me know what I am missing. IS there any additional configuration in need to do in the switch? > > PS: in both cases the destination computer is set to promiscuous mode. > > Regards > Rao > > > > > _______________________________________________ > Tcpreplay-users mailing list > Tcpreplay-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/tcpreplay-users > Support Information: http://tcpreplay.synfin.net/trac/wiki/Support _______________________________________________ Tcpreplay-users mailing list Tcpreplay-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/tcpreplay-users Support Information: http://tcpreplay.synfin.net/trac/wiki/Support _______________________________________________ Tcpreplay-users mailing list Tcpreplay-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/tcpreplay-users Support Information: http://tcpreplay.synfin.net/trac/wiki/Support
