clear collision

Hi all
I wonder how to clear the collision packet

eth0 Link encap:Ethernet HWaddr 00:02:A5:E8:31:26
inet addr:211.230.50.112 Bcast:211.230.50.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:550730 errors:0 dropped:0 overruns:0 frame:0
TX packets:484050 errors:0 dropped:0 overruns:0 carrier:205
collisions:349 txqueuelen:100
Interrupt:5 Base address:0x3000

collisions:349 ---> how to clear

is there any way to do so?

Re: clear collision

Collisions are created when network traffic can not get through. Packets collide.

The stats you see are not important, so long as collisions are not piling up. If they are, they are usually created by problems with your network configuration or physical setup.

ifconfig eth0 down

Then bring the card up, will probably clear the statistic, if not surely a system boot will. This will not address the root cause of the collision.

Re: clear collision

guess you should try to address the issue rahter than clearing the counters. there are some packet loss happening which is causing this error.

guess you need to monitor your network and try to get this fixed. (and dont ask me how! i dont know)

Re: clear collision

Hello!

If you mean clean collisions from the ifconfig
that you can try "ifconfig eth0 down"
and then "ifconfig eth0 up" and in most cases it will work but it depend also on how the driver writen.

Re: clear collision

On my box it doesn't. I jus see collisions back to the original number. It should be somewhere in the /proc directory, but I didn't find where. I'm reading somewhere that it's on NIC itself and can't be changed from OS, only on resettting physically... No help in man ifonfig either.

I agree anyway with the other to prefer to clear the problem rather than the counter...
