Hi,
I am trying to play with link aggregation feature on Sun x4100 (Solaris 10 06/06 + all patches)

Both NET0 and NET1 of my x4100 is plugged into Cisco 3560g gigabit ethernet switch.
NET0 is plugged into:
>cisco-3560g-1#sh runn inter GigabitEthernet 0/3
>Building configuration...
>
>Current configuration : 161 bytes
>!
>interface GigabitEthernet0/3
> switchport access vlan 2
> switchport mode access
> spanning-tree portfast
>end
NET1 is plugged into:
>cisco-3560g-1#sh runn inter GigabitEthernet 0/4
>Building configuration...
>
>Current configuration : 161 bytes
>!
>interface GigabitEthernet0/4
> switchport access vlan 2
> switchport mode access
> spanning-tree portfast
>end
Now in /var/adm/messages I can see a lot of messages like:
>Sep 7 12:43:13 ride ip: [ID 903730 kern.warning] WARNING: IP: Hardware address '00:14:4f:2a:11:48' trying to be our address 010.200.144.003!
Do I miss something? Should I do some extra setup on my cisco switch?
