Solaris

Hello !
i'm facing an anoying problem during configuration of our new T5220 Enperise server. I've upgarded 'em with a pci-e ethernet expantion card for four additional networkinterfaces using the nxge drivers. i could fix them to 100 fdx rather simple by adding the following settings to the
/platform/sun4v/kernel/drv/nxge.conf file:

adv_1000fdx_cap=0;
adv_1000hdx_cap=0;
adv_100fdx_cap=1;
adv_100hdx_cap=0;
adv_10fdx_cap=0;
adv_10hdx_cap=0;
adv_autoneg_cap=0;

so this was rather simple the hard part is to configure the built in e1000g
interfaces. i found some threads containing the modification of the
/kernel/drv/e1000g.conf like this:

# Driver.conf file for Intel e1000g Gigabit Ethernet Adapter
ForceSpeedDuplex=7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7; (autoneg)
AutoNegAdvertised=8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8; (autonegadvertise 100fdx only)

i also tried variations like
ForceSpeedDuplex=4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4; ( 100fdx)
AutoNegAdvertised=47,47,47,47,47,47,47,47,47,47,47,47,47,47,47,47;(autonegadvertise all supported modes)

but allways failed to fix the to 100fdx

dladm show-dev :
e1000g0 link: up speed: 100 Mbps duplex: half
e1000g1 link: up speed: 0 Mbps duplex: half
e1000g2 link: up speed: 0 Mbps duplex: half
e1000g3 link: up speed: 0 Mbps duplex: half
nxge0 link: up speed: 100 Mbps duplex: full
nxge1 link: unknown speed: 100 Mbps duplex: full
nxge2 link: unknown speed: 100 Mbps duplex: full
nxge3 link: unknown speed: 100 Mbps duplex: full

please help
cheers martin

Not sure this will work for you, but we were told to comment out the /kernel/drv/e1000g.conf lines for ForceSpeedDuplex and AutoNegAdvertised, which worked for us. (Guess you would have to then make sure your network is set to what you were looking for).

Why just not let them auto-configure?

Often becasue the driver, the card or the switch to which it is connected do not follow the standards correctly. The bge cards for example are well known for this and often have to be forced to the correct (full duplex) mode.

I've always heard that, and I only experienced problems with hme's, and not all of them, just a couple, and that was back in the Sol7, Sol8 days. I'd think that a card that's meant to autoneg because of the Gg capability should be able to handle autoneg for 100fdx just fine. If there are any concerns, I'd test the connection both ways and see if there really are any issues with an autonegotiated connectin.

maybe the net-tune script helps?

http://docs.cirkva.net/Sun/Solaris/Eis/S68net-tune_

read the first few lines on how to install an use the script!

thx but didnt work still getting the 100 HDX

@DukeNuke2 according the net-tune script havent found a proper ndd set
for the e1000g interfaces :-\

partially solved the problem by setting the switch-ports to autoneg and the nic settings below
still wont work with switch settings to 100 full duplex fixed

AutoNegAdvertised=8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8;
ForceSpeedDuplex=4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4;
