Configure 2 nics at different speeds.
Hi,
I have a sunfire v120 which I have setup to have one nic using 192.168.51.5 and the the other to be 192.168.151.5. The first nic is on a 100Mb switch and the other is connected to a 1Gb switch.
They are currently running at
InterfaceSpeedDuplex
--
eri0100 Mbit/shalf
eri1100 Mbit/sfull
I have forced the eri interfaces to connect at 100Mb Full duplex by setting the /etc/system file with the following;
set eri:eri_adv_autoneg_cap=0
set eri:eri_adv_100hdx_cap=0
set eri:eri_adv_100fdx_cap=1
Which has worked for the first nic.
How to I set the second nic to connect at 1Gb full duplex?
Thanks
chris

Chris,
You would need to install a Gigabit-capable Ethernet card
to the system's solitary PCI slot.
The ERI interface is only capable of 10/100 network speeds.

There are a number of fully qualified 10/100/1000 cards for that platform.

Hi, Thanks for the reply.I'll look at doing that.Also though I have two v240's which have bge nics, I believe to support 1Gb. Would I be able to setup the second nic at 1Gb, as per my original question?ThanksChris

Yes, the bge interfaces are capable of gigabit speeds.
"bge" = Broadcom Gigabit Ethernet chipset.
I've never had a need to do that sort of a configuration,
but it's plausable because you're going to manipulate
specific interfaces by name ( interface"0" and interface"1" ).
Go for it, then return to the forum and let us all know how it works out.

Have you actually determined that autonegotiation does not work?
I have not had a Sun NIC fail to autonegotiate properly since 1999.
Any so-called network admin who tells you that forcing speed-duplex by default is best practice is misinformed. Of course, sometimes you have no choice but to submit to their whims.
