If you are just creating from the command line and want cisco router
like subinterfaces, the following works (I have the vlan module built
into my kernel might need to load it otherwise.)
root@crab
(19:22:09 <~>) 0 # ifconfig bge0.1
ifconfig: interface bge0.1 does not exist
root@crab
(19:22:13 <~>) 0 # ifconfig bge0.1 create
root@crab
(19:22:15 <~>) 0 # ifconfig bge0.1
bge0.1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=3<RXCSUM,TXCSUM>
ether 00:e0:81:2d:a3:16
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
vlan: 1 parent interface: bge0
root@crab
(19:22:17 <~>) 0 # ifconfig bge0.1 destroy
Not certain how thats represented in rc.conf, Will have a look.
