Q: Using multiple ethernet controllers in Solaris 2.X

[Jeffrey Huff]

Has anyone configured a sun system with mulitiple ethernet controllers
in Solaris 2.X on SPARC?? I have a 630MP with the on board lance
ethernet controller and one on a FSBE/S SCSI-II/lance ethernet S-bus
card. I have setup both the hostname.le0 and hostname.le1. Prtconf
shows both le0 and le1 to be configured, but the ethernet address for
both cards is the same as the onboard controller from an ifconfig -a.
The ethernet controller in the FSBE/S does not seem to have it's own
ethernet address show up.

Any help or information would be appreciated.

Thanks in advance...

That's right. Sun uses same Ethernet address on all the interfaces.
This is correct behaviour. Using different addresses on all interfaces
is also correct. :-) This is a FAQ, I think. It shows up often enough
to be one.

If you want to attach both Ethernets to the same segment, think again.
Attach your fastest interface to your busiest segment.

Well, you can attach two interfaces to the same segment. The trick is
to use the ether option of ifconfig to set a different ethernet
address on the second interface.

Hi Jeffrey,

the system gets the MAC address for all adapters from a setting in
IDPROM at boot. Unusual, but true. As long as the two adapters are
connected to different ethernet segments you needn't worry about this.

If you want to use both interfaces on the same segment, you'll need
to use the command "ifconfig leX ether xx:xx:xx:xx:xx:xx" where leX is
the interface you want to assign the new MAC address xx:xx:xx:xx:xx:xx
to. Of course, this only works until the next reboot, so you may want
to put that command somewhere in your system boot files.

Good luck, and if you need a better explanation, let me know.
