Re: [discuss] how to configure vnic over vlan?

Maybe I'm missing something and maybe it's different in Illumos, but what about:


dladm create-vnic -l net0 -v 2 nge1.vlan2

(note: that's assuming that net0 is in fact your nge1 interface).
I.e. create a vnic not a vlan.

I'm also not sure if the dot is allowed in the vnic name, I suspect that it may not be.

I tend to call mine <zonename><vlan>, e.g. gaspra7

For zones, I've always create vnics over a physical interface. To date, the physical port did not have VLAN tagging. Given my server only has two physical ports and I want to bring in another network, I decided to try to configure VLAN tagging...
I shutdown all my zones and deleted all my existing vnics. Then I created two vlans over the physical interface:
  # dladm create-vlan -l nge1 -v 2 nge1.vlan2
  # dladm create-vlan -l nge1 -v 4 nge1.vlan4
Usually the physical interface I create vnics over is both "plumbed" and "up", so...
  # ifconfig nge1.vlan2 plumb up
  # ifconfig nge1.vlan4 plumb up
But now when I try to create a vnic, passing in the vlan interface, I get this error:
  # dladm create-vnic -l nge1.vlan2 vnic0
  dladm: vnic creation over nge1.vlan2 failed: invalid argument



I've also tried to create the zone using the vlan instead of a vnic:

  # cat test-zone.cfg
  create -b
  set zonepath=/zones/test
  set brand=ipkg
  set autoboot=false
  set ip-type=exclusive
  add net
  set physical=nge1.vlan4
  end
  # zonecfg -z test-zone -f test-zone.cfg
  # zoneadm -z test-zone install
WARNING: skipping network interface 'nge1.vlan4' which is used in the global zone.
It goes on to install the zone, but when I try to boot it, I get:

  # zoneadm -z test-zone boot
WARNING: skipping network interface 'nge1.vlan4' which is used in the global zone. zone 'test-zone': WARNING: skipping network interface 'nge1.vlan4' which is used in the global zone
  zone 'test-zone': failed to add network device: Error 0
  zoneadm: zone 'test-zone': call to zoneadmd failed
I've tried bringing the interface down and unplumbing it, but still nothing works...
I notice that Solaris 11 has a "modify-vlan" subcommand that is missing in illumos - is this needing to make this work? - is there any other way to have zones over vlans?
Any ideas?

Thanks,
Kent
