https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207701 Bug ID: 207701 Summary: vlan interface over failover lagg has empty/00:00:00:00:00:00 mac/ether address Product: Base System Version: 10.3-BETA2 Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: freebsd-bugs@virtualtec.ch CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Created attachment 167713 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D167713&action= =3Dedit comparison between 10.2-release and 10.3-prerelease dmesg We configure some servers with two interfaces as follows: - failover lagg0 on em0 and em1 - several vlans on lagg0 after upgrading our systems due to the openssl bug, they came up without networking. The reason was the vlan interfaces on the lagg got configured with empty mac addresses: vlan10: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1= 496 ether 00:00:00:00:00:00 inet 10.0.1.11 netmask 0xffffff00 broadcast 10.0.1.255=20 nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: active vlan: 10 parent interface: lagg0 where as with RELEASE-10.2, this looked as follows: vlan10: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1= 496 ether 00:30:48:7f:29:74 inet 10.0.1.11 netmask 0xffffff00 broadcast 10.0.1.255=20 nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: active vlan: 10 parent interface: lagg0 The lagg0 looks the same in both releases: lagg0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 15= 00 =20=20=20=20=20=20=20 options=3D4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_= MAGIC,VLAN_HWTSO> ether 00:30:48:7f:29:74 nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: active laggproto failover lagghash l2,l3,l4 laggport: em0 flags=3D5<MASTER,ACTIVE> laggport: em1 flags=3D0<> We're normally using a stripped own kernel config, but for this purpose I deliberately booted with 10.2-RELEASE and created a 10.3-PRERELEASE@r2963= 82 GENERIC kernel to have a verifiable configuration. Our rc.conf snippet to configure the interfaces looks as follows (there are more vlans configured than this): cloned_interfaces=3D"vlan10 lagg0" ifconfig_em0=3D"vlanhwtag up" ifconfig_em1=3D"vlanhwtag up" ifconfig_lagg0=3D"laggproto failover laggport em0 laggport em1 up" ifconfig_vlan10=3D"inet 10.0.1.11/24 vlan 10 vlandev lagg0 up" --=20 You are receiving this mail because: You are the assignee for the bug.=
