Did you want to have 802.1q (Ethertype 0x8100) for both inner and outer tags? From the ifconfig output it looks like you're using 802.1ad (Ethertype 0x88a8) for the outer tag: > vlan: 330 vlanproto: 802.1ad vlanpcp: 0 parent interface: mlxen0 This will *not* work with a switch configured for 802.1q, which this certainly looks like: > switchport mode trunk FreeBSD is absolutely capable of using the 802.1q Ethertype for both tags.
