Thanks for jogging my memory.  To answer some inquiries, Sun by default 
uses the same MAC address for NICs in the same subnet.  The solution now 
is to change the MAC address by using the following command:

#eeprom local-mac-address?=true

Having the same MAC on two NICs will confuse the switch which operates on 
low-level routing.

Kevin Korb noted using secondary interfaces on one NIC.  In my particular 
case, we wanted to separate the traffic on two separate NICs serving heavy 
web and SQL traffic.  To use secondary address on the same NIC:
# ifconfig hme0:1 <address> .....
