Sun Trunking 1.& kern Warning Hardware address trying to be our IP addresse

Question

Using Sun Trunking 1.3 on a solaris 10 11/06 V490 server.
setenv local-mac-address? is set to true
Obviously server Aggregate MAC address corresponds to first NIC local MAC address. Second NIC has its specific MAC address.
Aggregate seams OK (traffic continues undisrupted when unplugging a card)
but :
1) Should I worry kernel is logging from toime to time messages such as :
WARNING: IP: Hardware address '00:14:4f:3b:60:f4' trying to be our address IP_address !
2) There is no load balancing between the 2 NIC interfaces as reported by nettr -stats 0 interval=2
Traffic always flows using NIC 2.
Appreciated,
Lor.

Answer 1

That depends on the switch.
SunTrunking 1.3 is compatible with Cisco EtherChannel for example. I believe there's a manual configuration on the switch to say that these two ports are participating in an etherchannel linkage. SunTrunking is an 802.11ad protocol. If they haven't done that, then the switch is just assuming the two ports are normal and have separate hosts behind them.
If instead of SunTrunking you were using Solaris 10 Link Aggregation, then you'd ask the networking guys to turn on LACP, which sets up a communication so the devices can describe their trunk/network setup. SunTrunking doesn't let you do that.
What interfaces do you have on the Solaris box?
