Thank you for your replies. My notes follow :
1. The physical address must be different for each interface in the network and
can be changed using "ifconfig le1 ether a:b:c:d:e:f:g".
3. "/usr/sbin/arp -a" lists *some* of the physical addresses on the network.
'getethers' is a pd tool used for find physical addresses, available for
SunOS 4.1.3.
3. Solaris 2.x allows multiple IP address for each hardware interface.
4. Recommended reading : Internetworking with TCP/IP, Volume I, by Comer.
5. I'm sure that one person mentioned that the SBus card gives better
performance than the motherboard interface because it's data-buffered. I
can't find the message so apologies to the one who sent it.
I wanted to connect an ISDN router (allocated a Class C address by RIPE
NCC) and decided to use a dedicated (2nd card) in one of the Sparcs. The two
machines had been using a different Class C address. Instead of purchasing
a second repeater to link the two I wanted to investigate the option of
Multiple cards.
I've now got the money for a second repeater. Although it would have been
possible to use just one repeater I've decided to play safe and use a different
physical network.
