Dotaz: TX packets errors

[dusan456]

Zdravím,

mám problém, že stále narastajú TX errors na jednom našom servry. Neviete prosím poradiť, čo by to mohlo spôsobovať?

Kábel bol najprv napojený na eth0, tak som skúsil ho napojiť na eth1, ale problém pretrváva naďalej.

# ifconfig
eth1      Link encap:Ethernet  HWaddr 00:11:16:32:13:cc  
          --
          --
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:996905 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1001818 errors:24 dropped:0 overruns:0 carrier:0
          collisions:69999 txqueuelen:1000 
          RX bytes:109704274 (104.6 MiB)  TX bytes:811574963 (773.9 MiB)
          Interrupt:17 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:10665 errors:0 dropped:0 overruns:0 frame:0
          TX packets:10665 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:1038904 (1014.5 KiB)  TX bytes:1038904 (1014.5 KiB)

Ďakujem

Taky tam je vetsi mnozstvi kolizi - podle me se vase sitova karta a switch nedomluvili na rychlosti a/nebo duplexu. Co pise ethtool ?

To je ten samy stroj jako v dotazu server - restart pripojenia k internetu? V kazdem pripade plati to co jsem psal tam. Sit je potreba mit nastavenou ve shode s druhou stranou dratu. Je lepsi se domluvit, jestli maji zapnutou autodetekci a pokud ne, jake parametry maji byt. 100Mbps s half duplexem mi neprijde prilis obvykle.

Áno, je to ten istý stroj.

Na tom druhom stroji je všetko vporiadku a tam je duplex: full

Chcel som to takto nastaviť aj u tohto:

ifdown eth1;
/usr/sbin/ethtool -s eth1 speed 100 duplex full;
ifup eth1;

ale nedá sa mi to zmeniť a ostáva stále half.

Musite nejdriv vypnout autonegociaci:

ethtool eth1 autoneg off

a az potom

ethtool -s eth1 speed 100 duplex full

Kazopadne bych se primlouval za autonegociaci na obou stranach. Za pul roku na to zapomenete a budete to resit znova, az to pripojite nekam jinam.

[dusan456]

Ďakujem, presne tak som to nakoniec urobil. Už nie sú žiadné chybné pakety, vyzerá to byť už v poriadku. Ďakujem všetkým za pomoc.

[dusan456]

Pozerám aj, že RX a TX je off, nemalo by to byť on?

# ethtool -a eth1
Pause parameters for eth1:
Autonegotiate:	on
RX:		off
TX:		off
