Hi. Regarding "automatic vlan creation"

[Sebastian Hyrwall-2]

Hi

Now that FreeBSD has support for writing  , cloned_interfaces="em0.100"
instead of having to create for example a vlan0 and then specify vlandev
etc in ifconfig. What is the correct ifconfig-line in rc.conf for this?

ifconfig_em0.100="" or ifconfig_em0_100="" does not work.

Sincerely,
Sebastian H

You probably forgot to put if_vlan_load="YES" in /boot/loader.conf
ifconfig_em0_100="..." should work.

Hi.

Ah ok. Well I did add that but maybe there was a typo somewhere else.
Unfortuently I can't reach the server anymore (i wonder why heh ;) so I
gave this email a try before going to the datacenter to fix it.

Thanks for the input.

It should be ifconfig_em0_100.

btw, wouldn't it be nice not to bother with loader.conf when using
<device>.<vlan> syntax?
This patch will load if_vlan automatically in this case:

Sorry but my reation is: eww.  There's no way I'd commit that.  You'd be
randomly loading the vlan code for any interface that had a dot in it.

The real change we should make it to add device vlan to GENERIC.  It's
long past time for it to be in by default.

You are right, forgot about 'ifconfig rename'.

It's even better, what's need to be done to move it to GENERIC?
