Solaris 2.6 net install - OpenBoot 2.10
10/11/2017 14:54
I've been trying to use the network interface on an installed sunswift sbus card instead of the sparc onboard interface, but local-mac-address? true is ignored by the OS, which returns the same MAC for both interfaces (at least it does if I boot a 2.6 cdrom in single user mode).

The machine is an LX. Has anyone seen this before? It doesn't happen on an Ultra 60.

The only time when having the same address on multiple interfaces hurts is when you plug them all in the same net.

As all Suns have had networking, they all had a MAC address; so add on cards did not really need a MAC address; PCs never had this luxury, so a system ethernet address was never an option and so all add-on cards came with an ethernet address.

Dunno; but I would expect lots of failures at this time, specifically with the mechanical connectors and the fuses.

I know these LX's are steam age machines, but all three of them fail the external loop 'test net-tpe` on three different makes of 10/100 switch, which makes me think I may be doing something stupid. Are these things prone to faulty on-board ethernet interfaces? Thanks again.
