half duplex

Post by tindanos » Wed May 07, 2003 5:40 pm

Vill ändra mitt NIC till half duplex då detta tydligen skall hjälpa om man har problem med comhems dhcp men vet inte inte riktigt hur jag skall göra.

Läste någonstans att jag skall sätta
alias tulip options=9 (alt 12) i modules.conf
Testade detta men verkar inte ge något resultat
kanske skall jag skriva
alias eth1 tulip options=9 i modules.autoload istället

tulip-diag ger

Code: Select all

root@xxxxxx root # ./tulip-diag -a
tulip-diag.c:v2.17 5/6/2003 Donald Becker (becker@scyld.com)
 http://www.scyld.com/diag/index.html
Index #1: Found a Digital DC21041 Tulip adapter at 0x1000.
 * A potential Tulip chip has been found, but it appears to be active.
 * Either shutdown the network, or use the '-f' flag to see all values.
Digital DC21041 Tulip chip registers at 0x1000:
 0x00: ffe08000 ffffffff ffffffff 1169b000 1169b200 fc660000 fffe2202 ffffebef
 Port selection is full-duplex.
 Transmit started, Receive started.
  The Rx process state is 'Waiting for packets'.
  The Tx process state is 'Idle'.
  The transmit unit is set to store-and-forward.
  The NWay status register is 45e1d5c8.
    Link Partner ability: 45e1.
    100baseTx link good.
    10baseT link good.
dmesg ger

Code: Select all

root@xxxxxxx root # dmesg | grep eth1
eth1: Digital DC21041 Tulip rev 17 at 0x1000, 21041 mode, 00:80:AD:A9:24:06, IRQ 11.
Skulle enn annan variant kunna vara
alias tulip full_duplex=1
Här indikeras ju även att options inte kan ta högre värde än 8 ju

Code: Select all

root@xxxxx modules.d # modinfo tulip
filename:    /lib/modules/2.4.20-gentoo-r2/kernel/drivers/net/tulip/tulip.o
description: "Digital 21*4* Tulip ethernet driver"
author:      "The Linux Kernel Team"
license:     "GPL"
parm:        tulip_debug int
parm:        max_interrupt_work int
parm:        rx_copybreak int
parm:        csr0 int
parm:        options int array (min = 1, max = 8)
parm:        full_duplex int array (min = 1, max = 8)
Hoppas någon kan hjälpa mig med mitt problem

En variant är att styra det via mii-tool eller tulip-diag. Jag har ingen erfarenhet av tulip nätverkskort men följande fungerar på intel och många andra:

# 10mbit, half-duplex
mii-tool -F 10baseT-HD eth0
# 100mbit, half-duplex
mii-tool -F 100baseTx-HD eth0

eller

# 10mbit, half-duplex
tulip-diag -F 10baseT-HD eth0
# 100mbit, half-duplex
tulip-diag -F 100baseTx-HD eth0

mii-tool -v talar om vilken hastighet du kör idag och vad den andra sidan klarar av.
