Starting 3c905B cards with full duplex upon booting

Starting 3c905B cards with full duplex upon booting

Post by CSLinuxBo » Sun, 25 Nov 2001 06:41:55



Hello all,

      A quick question.  How do I make it so I can pass options to a
kernel driver at boot time.  The reason for this is that the network
cards on our firewall will not come up by default with the full duplex
option set.  Therefore we have to always manually stop the network and
unload the NIC drivers and then reload them with the "options
full_duplex=1,1,1,1" option (we have 4 NICS on our firewall)".  Can this
be passed via the modules.conf file?  I am running RedHat 7.1 with the
2.4.14 kernel.  Thanks in advance.

Mike

If the driver is compiled as a module, you can use

option 3c59x full_duplex=1,1,1,1

in your /etc/modules.conf.

Could you not use the DOS utility (3C9X5CFG.EXE IIRC) to set the cards to
use full duplex mode by default?

1. 3com 3c905b cyclone full/half duplex switch

Hi

I have bought a 3com 905b cyclone card which doesn't perform that well
(about 98% packet loss). I suspect it to be in full duplex (while it is
connected to a half-duplex network) but the config program for the 3c90x
that I downloaded from 3com's site states that it is in half-duplex. (I'm
talking about 3C90XCFG.EXE - dos program)

Now are there any utilities, either for windows or for linux, that force it
to be in halfduplex? For windows I know there are, because they were shipped
with the cards I have installed for a company. But I can't find them on the
3com site.

In Linux, I've read /usr/src/linux/Documentation/networking/vortext.txt,
which tells me that there are specific options to force the card to be in
full duplex. So am I right to conclude that it defaults to half duplex?

Please send me such utility or give me an url? Thanks so much in advance,
Willem
