Cloning VLAN interfaces

[jammin2night]

Thanks for you reply!  All goes well until:

(root at charon) ~# ngctl name re0-hub: downstream re0-vlan
ngctl: usage: name <path> <name>
(root at charon) ~#


(root at charon) ~# ngctl list
There are 6 total nodes:
   Name: <unnamed>       Type: vlan            ID: 0000001c   Num hooks: 
1
   Name: em0             Type: ether           ID: 00000002   Num hooks: 
0
   Name: re0             Type: ether           ID: 00000001   Num hooks: 
2
   Name: vlan10          Type: ether           ID: 00000003   Num hooks: 
0
   Name: ngctl4248       Type: socket          ID: 00000027   Num hooks:

   Name: re0-hub         Type: hub             ID: 00000017   Num hooks:
