Multiple Ethernet Interfaces (SunOS)

How do you handle multiple ethernet interfaces?

SunOS normally assigns the same MAC address to every physical interface. This is fine when each interface it plugged into a different network. However, if you want to place more than one interface on the same subnet, you need to assign them each a unique MAC address.

To do this, create a script that can be run at boot time to assign MAC addresses to each interface.

# put unique MAC addresses on each of the qe port

do
   {
       ioname=`cat /etc/hostname.${io}`
       if [ "$ioname" != "xx0" ]
       then
               ifconfig $io ether "`cat /etc/etheraddr.${io} 2> /dev/null`"
       else
               ifconfig $io down
       fi
   }
done

Editing SPARC 10 Serial Pinout (RJ45)

The Host Circuit Board on a Sparc10 system is a DB25 connector with two serial ports wired into it, Port A and Port B.

PIN	SIGNAL	PORT	SIGNAL	SIGNAL	Common color coding
2	TD	A	TD		brown
3	RD	A	RD		white
4	RTS	A	RTS		green
5	CTS	A	CTS		yellow
6	DSR	A	DSR		blue
7	GND	AB	GND	GND	black
8	DCD	A	DCD		orange
11	DTR	B		DTR
12	DCD	B		DCD
13	CTS	B		CTS
14	TD	B		TD
15	TC	A	TC
16	RD	B		RD
17	RC	A	RC
18	TC	B		TC
19	RTS	B		RTS
20	DTR	A	DTR		red
24	TCO	A	TCO
25	TCO	B		TCO

So, for example;

port A pin 4 is RTS and connects to host pin 4

port B pin 4 is RTS and connects to host pin 19
