Hi I am having an issue with a new FreeBSD 10.2-RELEASE system when using LAGG= s. Everything works fine until I try to do a reboot of the system. With thi= s issue the system does a shutdown but reports an error with the interfaces= that belong to the LAGG (which also have VLANs define) and then halts=2C i= t will not reboot=3B a power cycle is required. root@Pine:~ # uname -a FreeBSD Pine.local 10.2-RELEASE FreeBSD 10.2-RELEASE #0 r286666: Wed Aug 12= 15:26:37 UTC 2015 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GE= NERIC amd64 /etc/rc.conf: if_vlan_load=3D"YES" # HP V1910-24G Switch Trunk ifconfig_igb1=3D"up mtu 1500" ifconfig_igb4=3D"up mtu 1500" ifconfig_igb7=3D"up mtu 1500" ifconfig_igb8=3D"up mtu 1500" # Setup new Virtual Interfaces cloned_interfaces=3D"lagg1 vlan101 vlan102 vlan103" # LAGG Configuration ifconfig_lagg1=3D"laggproto lacp laggport igb1 laggport igb4 laggport igb7 = laggport igb8" # Setup VLANs ifconfig_vlan101=3D"inet 192.168.1.208/24 vlan 101 vlandev lagg1" ifconfig_vlan102=3D"inet 192.168.2.208/24 vlan 102 vlandev lagg1" ifconfig_vlan103=3D"inet 192.168.3.208/24 vlan 103 vlandev lagg1" # Setup extra IPs for Layer 3 Load Balancing ifconfig_vlan101_aliases=3D"inet 192.168.1.209/32" ifconfig_vlan102_aliases=3D"inet 192.168.2.209/32" ifconfig_vlan103_aliases=3D"inet 192.168.3.209/32" =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= Errors on shutdown -r now =0A= =0A= ...=20 =0A= =0A= Uptime: 3d20h44m15sigb8: Interface stopped DISTRIBUTING=2C=0A= possible flapping=0A= =0A= igb1: Interface stopped DISTRIBUTING=2C=0A= possible flapping=0A= =0A= igb7: Interface stopped DISTRIBUTING=2C=0A= possible flapping=0A= =0A= igb4: Interface stopped DISTRIBUTING=2C=0A= possible flapping=0A= =0A= =0A= =0A= =0A= =0A= Has anyone else run into this behavior with LAGGs and VLANs?
