Talk:VLAN

Hello,

Using the following configuration Alpine 3.19.0 kernel 6.6.13-0-lts does not seem to work depsite the vlan package being present.

auto vlan8
iface vlan8
	address 192.168.0.2/24
	gateway 192.168.0.1
	vlan-raw-device eth0

Has anyone tested this recently ?

Hi there, looks like the very old examples in the article are using the wrong syntax for busybox's ifup... (the vlan package doesn't use ifupdown-ng)... The address and netmask lines cannot be combined. Also good practice to explicitly specify if the interface is DHCP or static... See if something like this will work for you:

auto vlan8
iface vlan8 inet static
	address 192.168.0.2
	netmask 255.255.255.0
	gateway 192.168.0.1
	vlan-raw-device eth0

My testing only consisted of seeing if the networking service could be bought up successfully, I have no idea if the VLAN tagging is working or not.

BTW, for clarity's sake, I set preformatting on for the config in your post to make it easier to see the differences, hope you don't mind!

Hey, I just tested this on 3.21, looks good

I'll try pinging soon and update if it were really broken.

I havent done larger changes to pags on the wiki in a decade but maybe we (the ominous 'someone' we should change the vlan page to primarily cover the current case and only reference a different page for the old setup with the vlan package)
