[SOLVED] VLANs and parent interface

Pkuutn · 07-29-2015, 12:13 PM

Hello everybody!
Is there a way in Linux to filter out tagged packets on parent interface completely?
I.e. I have eth0, eth0.7 and eth0.8 up and running, eth0.7 and eth0.8 do get their tagged packets all right, and eth0 got _all_ of them - tagged and untagged. I'd like to have just untagged packets on eth0, if that's possible.
Thank you.

Alias interfaces receive untagged packet.

macvlan virtual interface works for me!

in /etc/network/interfaces I have smth like:

Code:

iface eth0 manual
pre-up ifconfig $IFACE up
post-down ifconfig $IFACE down

auto peth0
iface peth0 inet static
        address 192.168.0.1
        netmask 255.255.255.0
        pre-up ip link add peth0 link eth0 type macvlan

no more tagged/untagged frames mess!
