The conclusion is that the switch has some problem. In fact, for the first 5 minutes, it works like a switch and then it works like a hub. The switching table is messed up by the intense traffic, we believe. Other cheaper switches (netgear fast esthernet switch FS108 ) have the same problem. We use a CentreCom FS708, and then the problem is solved. Of course other expensive and professional switches should be ok too, we think. Just some information.

Host_10.1--->10.254_router_1.254--->Linksys 5-port workgroup switch-->Host1.1 | | | | v v Host_1.10 Host_1.5 Host_10.1 sends 1000 packets/s (pps) to Host_1.10. Host_1.10 receives the packets. But Host_1.5 receives the packets too, while Host_1.1 does not (by tcpdump -i any). What is the possible reason? Thanks!
