I just hooked up an asante 8 port ethernet switch that resides in between my cable modem and my box, im getting some errors and collisions. it doesnt seem to be affecting things but i'd like to fix the issue if i can. heres the gory details

Code:
-bash-2.05b# ifconfig

eth0      Link encap:Ethernet  HWaddr 00:48:54:81:6A:98

         inet addr:68.44.125.24  Bcast:68.44.125.255  Mask:255.255.255.0

         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

         RX packets:21267 errors:0 dropped:0 overruns:0 frame:0

         TX packets:953 errors:0 dropped:0 overruns:0 carrier:0

         collisions:2 txqueuelen:1000

         RX bytes:2038867 (1.9 Mb)  TX bytes:116351 (113.6 Kb)

         Interrupt:11 Base address:0x1480

lo        Link encap:Local Loopback

         inet addr:127.0.0.1  Mask:255.0.0.0

         UP LOOPBACK RUNNING  MTU:16436  Metric:1

         RX packets:176 errors:0 dropped:0 overruns:0 frame:0

         TX packets:176 errors:0 dropped:0 overruns:0 carrier:0

         collisions:0 txqueuelen:0

         RX bytes:28053 (27.3 Kb)  TX bytes:28053 (27.3 Kb)

any thoughts on how to figure out whats wrong and how to fix the issue?

I only see 2 collisions in that output. Does it do it often or in specific intervals?

I havent noticed any specific intervals but i checked uptime and ifconfig again and after being up for 9:33

i have 311 collisions:

Code:
-bash-2.05b# uptime

07:06:15  up  9:35,  6 users,  load average: 0.06, 0.06, 0.07

-bash-2.05b# ifconfig eth0

Collisions are normal in a standard network. Granted, if you have 2,000,000,000 collisions (exaggeration) every minute, you've got a problem. Make sure you don't have a hub daisy-chained to that switch you're using. Basically, if it connects to the same routing device twice, you're gonna have collisions. The whole thing with collisions is that both devices are trying to talk to your switch at the same time, so it shows you a pretty orange light and re-sends the packet, all in a matter of milliseconds. You shouldn't notice too much slowdown or anything of the like. Hope this helps! Oh, and is that nine hours, or nine minutes?
