Cisco Switching/Routing :: 2900 - Nexus 7010 Layer 2 VLan 11 Active But Interface Shutdown

I understand the vlans on the catalyst side of the house on 2900 to 6500 Catalyst switches.
 
This 7010  running nx-os 5.1(3) I did not setup, but have to manage it.  Hasn't really been a proble till now.
 
My nexus 7010 has a Layer 2 only vlan 11. It is "Active" but the interface is "shutdown".  Yet, it is passing traffic across the directly connected  ports on the nexus 7010 and to other switches in my network.  Vlan 11 is being set out via VTP to all my switches and things are running fine.
 
I need to create another L2 only Vlan.  I can't seem to find any docs  that indicate that a Layer2 vlan Interface on nx-os should be in  "shutdown" mode as part of the setup. I do see in the docs where it has  to be set "Active" as part of the process.
 
Is this the correct way to seutp a L2 only vlan on nex-os? Leave the interface in "shutdown" but make it "Active"?
 
Mystery Vlan 4 and 6
The mystery deepens.  I have other L2 vlans ,Vlan4&6 that are NOT defined as "Interface Vlan4" in the nexus config, yet it is applied to GigE ports on the nexus and these Vlans 4/6is also being sent out VTP to all switches.  Even weirder is that these vlans have names associated with the numbers.  These are valid Vlans that were configured on the old 6509 before the Nexus was installed.
 
I have checked all switches, NONE are running in Server mode for VTP, all are in CLIENT. The nexus 7010 is the only device running in VTP Server mode.
