Hi, 

# uname -a
FreeBSD rsv-filer 12.0-ALPHA5 FreeBSD 12.0-ALPHA5 #0 r338557: Mon Sep 10

Problem "seems" to have changed from pass no traffic to do not detect link on
parent interface (I have this behavior on lagg on 11.2) :

ix1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=e53fbb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,WOL_UCAST,WOL_MCAST,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:f4:34:a1
        media: Ethernet autoselect
        status: no carrier
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
vlan3402: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=600703<RXCSUM,TXCSUM,TSO4,TSO6,LRO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:f4:34:a1
        inet 10.194.101.101 netmask 0xffffff00 broadcast 10.194.101.255 
        groups: vlan 
        vlan: 3402 vlanpcp: 0 parent interface: ix1
        media: Ethernet autoselect
        status: no carrier
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

Configuration is done using rc.conf :

ifconfig_ix1="up"
vlans_ix1="vlan3402"
create_args_vlan3402="vlan 3402"
ifconfig_vlan3402="10.194.101.101/24"

This machine is connected to a Cisco 6800 thru a Twinax cable, so the media
should be : media: Ethernet autoselect (10Gbase-Twinax
<full-duplex,rxpause,txpause>)

On the switch the configuration is pretty simple :
interface TenGigabitEthernet3/5
 description Server: rsv-filer
 switchport
 switchport trunk native vlan 3402
 switchport mode trunk
 switchport trunk allowed vlan 3401-3403
 switchport nonegotiate
 mtu 9216
 logging event link-status
 flowcontrol send on
 spanning-tree portfast edge trunk
 spanning-tree bpduguard enable
!
On the switch side the port is not shut because any security stuff...

Regards
