[solved] Collisions problem

Hi! My first post here

I have a linux router running archlinux and i got this with ifconfig:

eth0      Link encap:Ethernet  HWaddr 00:0E:A6:2F:51:54
          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1278293 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1449231 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:440509859 (420.1 Mb)  TX bytes:1360369533 (1297.3 Mb)
          Interrupt:18 Base address:0xc000

eth2      Link encap:Ethernet  HWaddr 00:4F:4E:16:05:87
          inet addr:10.1.1.1  Bcast:10.1.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1449773 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1258700 errors:0 dropped:0 overruns:0 carrier:0
          collisions:87945 txqueuelen:1000
          RX bytes:1360634458 (1297.6 Mb)  TX bytes:438376026 (418.0 Mb)
          Interrupt:20 Base address:0x6000

Look at the collisions number on eth2!! That ethernet card is directly connected to an ADSL router (eth0 is connected to an ethernet switch, but that doesn't matter...). 

So where are those collisions coming from??? I changed the UTP cable and the collisions are still there...

Thanks!

Re: [solved] Collisions problem

Well, I solved it... A duplex mismatch was causing the problem.
