[FUG-BR] Netgraph

[Eduardo Schoedler]

Alguém tem idéia de como eu faço para pegar o tráfego específico de uma
interface no Netgraph ?
Estou fazendo:

mkpeer igb0.2000: netflow lower iface0
name igb0.2000:lower netflow0
connect igb0.2000: netflow0: upper out0

Só que ele não reconhece "igb0.2000" como interface:

# ngctl list
There are 9 total nodes:
  Name: <unnamed>       Type: ether           ID: 00000008   Num hooks: 0
  Name: ngctl96579      Type: socket          ID: 00000014   Num hooks: 0
  Name: ipfw            Type: ipfw            ID: 00000001   Num hooks: 0
  Name: bce0            Type: ether           ID: 00000006   Num hooks: 0
  Name: bce1            Type: ether           ID: 00000007   Num hooks: 0
  Name: igb0            Type: ether           ID: 00000002   Num hooks: 0
  Name: igb1            Type: ether           ID: 00000003   Num hooks: 0
  Name: igb2            Type: ether           ID: 00000004   Num hooks: 0
  Name: igb3            Type: ether           ID: 00000005   Num hooks: 0


Porém, quando eu crio no formato "vlanX" (o qual eu não gostaria de usar),
ele reconhece:

# ifconfig vlan create
vlan1

# ngctl list
There are 10 total nodes:
  Name: <unnamed>       Type: ether           ID: 00000008   Num hooks: 0
  Name: ngctl96656      Type: socket          ID: 00000018   Num hooks: 0
  Name: ipfw            Type: ipfw            ID: 00000001   Num hooks: 0
  Name: bce0            Type: ether           ID: 00000006   Num hooks: 0
  Name: bce1            Type: ether           ID: 00000007   Num hooks: 0
  Name: ***vlan1***     Type: ether           ID: 00000017   Num hooks: 0
  Name: igb0            Type: ether           ID: 00000002   Num hooks: 0
  Name: igb1            Type: ether           ID: 00000003   Num hooks: 0
  Name: igb2            Type: ether           ID: 00000004   Num hooks: 0
  Name: igb3            Type: ether           ID: 00000005   Num hooks: 0
