3C905C - nejde full duplex

[Rainbow]

V robote na serveri je tato sietovka. Nech sa snazim ako chcem, na switchi stale svieti 100mbps half duplex. "mii-tool -F xxx" ani "mii-tool -A xxx" nerobi nic. Co s tym kua je Jadro Linux 2.6.7.

Me se osvedcilo prepinat pri nahrati modulu,
#modprobe 3c59x options=0x200 , ale nevim jestli pomuze, nedavno jsem mel v kompu sitovku, ktera mi s donaldovym driverem poradne nejela, a musel jsem pouzit tu od 3COMu.
Jedu tak 2.6kovy kernely

[Rainbow]

Teraz s tym nic robit nemozem, lebo cez SSH je to dost nebezpecne...a navyse nemozem pozerat na LEDky switchu. To bude zase "sranda" - driver som zakompiloval do jadra - myslel som si, ze to bude fungovat bez problemov... Ked vyjde jadro 2.6.8, tak to asi cele prerobim a pripadne vyskusam driver od 3Comu.

[Rainbow]

Tak driver od 3Comu nevyskusam, lebo je takmer 3 roky stary...pre 2.4.x

/usr/sbin/ethtool -s ${IFACE} port aui duplex full

takhle to mam pro ronju, ale jestli to fackt jede full duplex vi Buh. Ono se to pri half chova uplne stejne.

Pak mam jeste trochu jinsi mrsku
# eth1 - PCI 10/100 3c595 XL - LAN
alias eth1 3c59x
options eth1 options=4
# options eth1 options=4 full_duplex=1

ta zase pri full duplex sice jede, ale je tam chyb jak maku.

To tam zjavne nefunguje. U mna doma to funguje:

bash-2.05b# ethtool eth0
Settings for eth0:

ale prezmenu nefunguje mii-tool (3c509 zjavne nema MII)

[Glottis]

zkus utilitku primo od 3comu, tam to jde nastavit na tvrdo

[Rainbow]

Zajtra tam idem, tak vyskusam ten DOSovsky program - najprv na PC vedla (je tam rovnaka sietovka, ale windows...) a potom na serveri. V tom Linuxovom driveri je asi nejaky bug, ked to vobec nereaguje na mii-tool...

[Arteee]

Jo mam obdobny problem.... ethtool nefunguje a porad nahazuje 10Mb HD... pokud nastavym mii-tool 100Mb FD tak se nic nestane, jadro 2.6... Je taky 3Com ale jedna 590B a druha 590C... delaji to obe

[Rainbow]

Tak uz som to vyriesil. Tym DOSovskym programom (3c90xcfg) som zistil, ze to bolo nastavene na 100mbps full-duplex. Nastavil som vsetko na AUTO, ulozil, vypol a zapol - a potom to neslo vobec - ani LINK. Tak som vypol a zapol znovu a uz to ide na 100mbps full-duplex Vyriesil sa tym problem s pomalostou siete medzi serverom a ostatnymi pocitacmi, ktore isli na 100mbps full-duplex.
