vr0 interface and VLAN tagging

Hi list,
I've made some progress.. my rc.conf looks like this:
cloned_interfaces="vlan100 vlan200 vlan254"
ifconfig_vr0="up"
ifconfig_vlan100="inet 192.168.100.1 netmask 255.255.255.0 vlan 100 vlandev vr0"
ifconfig_vlan200="inet 192.168.200.1 netmask 255.255.255.0 vlan 200 vlandev vr0"
ifconfig_vlan254="inet 10.254.254.252 netmask 255.255.255.0 vlan 254
vlandev vr0"
defaultrouter="10.254.254.254"
Switch config has stayed the same, what I want to do now is do a
one-liner on the vr0 interface so I can bring it up and set the speed
duplex to 100/full. When I do:
ifconfig_vr0="up media 100baseTX mediaopt full-duplex"
It doesnt seem to work, any ideas what I'm doing wrong?
Cheers,
Will
