Possibly the length of the cable ?

It is a 5m cable. It is also the 'common' cable - it is unplugged from the router and plugged into the bridge (the other side stays in the switch).

    Hi all,

    I have the following problem. A Linux box configured as a bridge. One
    interface connects to the router via a crossover cable, the other
    connects to a switch via the cable that used to go to the router.

    Now I get the following:

    [root@localhost net]# ifconfig eth3
    eth3      Link encap:Ethernet  HWaddr 00:03:2D:07:61:5D
               UP BROADCAST MULTICAST  MTU:1500  Metric:1
               RX packets:1969134 errors:0 dropped:0 overruns:0 frame:176459
               TX packets:2186662 errors:0 dropped:0 overruns:0 carrier:0
               collisions:0 txqueuelen:1000
               RX bytes:492595115 ( 469.7 Mb)  TX bytes:579725462 (552.8 Mb)
               Interrupt:17

    eth3 is the interface that connects to the switch.  As you can see, 1 in
    10 rx packets are framing errors.

    What are possible causes for this? The cable is a constant, so is not
    likely to cause problems, so what else can possibly cause such a high
    number of frame errors?

    Any help appreciated.

    Thanks,

    Justin
