Why the NIC addresses are the same from lltstat -vvn? How can they be fixed?

Problem

 

By default, Sun systems assign the same <MAC> address to all interfaces.
To avoid this, configure the system to assign unique <MAC> addresses by
setting the <eeprom> parameter local-<mac>-address? to true.

Solution

 

Example:
===
# eeprom |grep local-mac
local-<mac>-address?=false
# /sbin/lltstat -vvn | more
LLT node information:
Node State Link Status Address
* 1 csvcs6 OPEN
qfe:0 UP 08:00:20:B6:D1:D9
qfe:1 UP 08:00:20:B6:D1:D9
 
# eeprom local-mac-address?=true
# eeprom |grep local-mac
local-mac-address?=true
# /sbin/lltstat -vvn | more
LLT node information:
Node State Link Status Address
* 1 csvcs6 OPEN
qfe:0 UP 08:00:20:B6:D1:D9
qfe:1 UP 08:00:20:B6:D1:D9
# reboot
# eeprom |grep local-mac
local-mac-address?=true
# /sbin/lltstat -vvn | more
LLT node information:
Node State Link Status Address
* 1 csvcs6 OPEN
qfe:0 UP 08:00:20:B4:08:90
qfe:1 UP 08:00:20:B4:08:91
