Set Intel Pro 100 S Dual port ethernet speed from Linux

[ady2k]

I used Compaq Server DL 580 with ethernet card Intel pro 100 S dual port autosense. And I installed Linux Red Hat 6.2.
My question :
1.How could I configure the ethernet port speed from linux to fix the ethernet port speed to 10 or 100 Mbps ?
2. What software could I use to set the ethernet port speed from Linux?
Thank's

Hi,

You should be able to set options in your /etc/modules.conf file (might be /etc/conf.modules on older linuxes) :

alias eth0 eepro100
options eepro100 options=0x30, 0x30

The 0x30 = full duplex 100mbs for cards 1 & 2.
(0x50 = full duplex 10mbs)

See -->

Hope this helps

I already tried your solution. But I still had a problem.
After I rebooted the linux server few times only 1 ethernet port can work well.Because this Intel Ethernet Card have 2 port for 1 card.
Any solution for this problem ?
Thanks

Hi,

Presumably, that card would be seen as eth0 and eth1 so maybe you just need :

alias eth0 eepro100
alias eth1 eepro100
options eepro100 options=0x30, 0x30

hi there

When working with Intel NICs, do yourself a big favour and use the e100 driver which Intel itself writes, rather than the old eepro100. It has a number of amazing features, which amongst others allow you to offload utilization/processing from the CPU to the NIC controller. It also allows VLANs (virtual LANs) on a single card (or group of cards), as well as teaming (combining several interfaces into one big virtual interface). (kinda like partitioning/"RAID" for your network connection.) Both of these have to be supported by your switch.

The e100 driver is available in binary form (just make install it) and is included into later versions of the common distibutions.

Intel have definitely done their work on this one. I must say that since using this driver, I am looking at NICs in a whole new light. the Intel NICs are by far my favourate, and we never have enough of them when building a new box (we do however have lots of TLANs and 3COMs, which we rather not use these days

I want to set Intel ethernet port speed to 100 Mbps Full Duplex.With my experience : Intel ethernet card had a problem to connect to Nortel/Bay Network switch.Because Intel Ethernet Card and Nortle/Bay Network switch used autosense.But that two products can not match the ethernet port speed.Why I want to set dedicated speed from both sides.
I can not get any utilities under DOS from Intel to set the ethernet port speed until now.I only can download diagnostic utility under DOS from Intel.
So I want to find the solution from Linux.
