crossbow discuss - Jan 2009 - dladm delete-vnic (last one) breaks physical link

(reposting to crossbow, sorry if you got duplicates)

I am not sure if this is reported, cause I am not sure how to search  
for this. I am hoping that someone here will know what I mean by this.

We just installed nvx105 and I was playing with vnic''s.

iml-v40z-4# dladm create-vnic -l bge0 vnic0

.. here you can plumb/up/dhcp/etc have fun, down/unplumb..

iml-v40z-4# dladm delete-vnic vnic0
Once I delete the vnic, my bge0 connection stops working. From what I  
can tell, its no longer "listening" to arp replies. I can see the arp
response in snoop, but it keeps asking (who is x.x.x.x).

If I create another vnic, it starts working again, delete it, it stops  
working.

I can get around it by re-plumbing bge0.

Is this a known issue?

Thanks in advance,
