configuring a network interface on solaris:
ifconfig eri1 plumb
ifconfig eri1 up
ifconfig eri1 192.10.2.27 netmask 255.255.255.0 broadcast 192.10.2.255 up
if you want to make the ip address permanent you need to make a file called /etc/hostname.eri1 to do this type:
echo 192.10.2.27 > /etc/hostname.eri1
also, don't forget to add entries to /etc/hosts and /etc/netmasks
