Creating a vnic on top of an aggregation (lacp) results in connectivity lost

Hi,

I have a strange behaviour creating a vnic over an aggragation on a M3000 with bge interfaces:

my network configuration is setup as an aggregation over two bge nics with LACP enabled.

Everything works fine, but creating a vnic on that aggregation (no ip address assigned, just creating) as

     dladm create-vnic -l aggr0 vn1

the host is unreachable. After deleting the vnic everything works fine again!

This happens only on bge interfaces and started with SRU 11.3.9.4.0

(it works with SRU 11.3.8.7.0 for every interface type and thers're no problems with the latest SRU on e1000g interfaces)

Has anybody some ideas?
