           Summary: [LAGG] Problem with second laggport
           Product: Base System
           Version: 11.1-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

Hello,

I had Freebsd 11.0-Release with configured lagg interface like this:

# LACP
ifconfig_lagg0="laggproto lacp laggport ix0 laggport ix1 192.168.202.254
netmask 255.255.255.0"

after upgrade to:
FreeBSD Gagarin 11.1-STABLE FreeBSD 11.1-STABLE #0 r321860

I have problem with second laggport:
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=e400bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:bd:65:58
        inet 192.168.202.254 netmask 0xffffff00 broadcast 192.168.202.255 
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: active
        groups: lagg 
        laggproto lacp lagghash l2,l3,l4
        laggport: ix0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
        laggport: ix1 flags=0<>

flags=0, 


rc.conf is the same like as for Freebsd 11.0-Release

ifconfig shows no carrier but connectivity is done correctly

ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=e400bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:bd:65:58
        hwaddr 0c:c4:7a:bd:65:58
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (10Gbase-LR <full-duplex,rxpause,txpause>)
        status: active
ix1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=e400bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:bd:65:58
        hwaddr 0c:c4:7a:bd:65:59
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: no carrier


When I removed laggport ix1 from rc.conf and reboot machine, ix1 works normaly

ix1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=e400bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:bd:65:59
        hwaddr 0c:c4:7a:bd:65:59
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (10Gbase-LR <full-duplex,rxpause,txpause>)
        status: active

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=e400bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:bd:65:58
        inet 192.168.202.254 netmask 0xffffff00 broadcast 192.168.202.255 
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: active
        groups: lagg 
        laggproto lacp lagghash l2,l3,l4
        laggport: ix0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>


and I can add ix1 to lagg0:
# ifconfig lagg0 laggport ix1

and all laggports works:

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
       
options=e400bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 0c:c4:7a:bd:65:58
        inet 192.168.202.254 netmask 0xffffff00 broadcast 192.168.202.255 
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: active
        groups: lagg 
        laggproto lacp lagghash l2,l3,l4
        laggport: ix0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
        laggport: ix1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
