Is it possible to use this method through rc or must I stick with creating
vlan1, vlan2, vlan3, etc and setting the vlanid and vlandev since my attmpts
have yielded no success.

Eg.
rc.conf:
ifconfig_em0="up vlanhwtag vlanmtu"
ifconfig_em0.100="inet 10.1.2.3/24"

goliath# /etc/rc.d/netif start
/etc/rc.conf: ifconfig_em0.100=inet 10.1.2.3/24: not found
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
....

and the interface is never created, with or without:
cloned_interfaces="em0.100"

Any suggestions?
