    Subjectdon't use cheap switches under some scenarios
    Hi, all,
    I asked before why my linksys workgroup 5-port switch worked like
    a hub
    under heavy traffic (10mb/s) into one socket of the switch. 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.

    It is really weird!

    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?
