OK, thanks everyone whom replayed. E.g. NONE. The problem seems to be related to LACP trunking. Disabling LACP and configuring trunk in =91loadbalance=92 mode puts all = in desired state (even after reboot). lagg0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> = metric 0 mtu 9000 = options=3D8407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCS= UM,TSO4,TSO6,LRO,VLAN_HWTSO> ether 00:25:90:e3:71:f2 inet 172.16.0.234 netmask 0xfffff800 broadcast 172.16.7.255 inet6 fe80::225:90ff:fee3:71f2%lagg0 prefixlen 64 scopeid 0x5 inet 172.16.0.231 netmask 0xfffff800 broadcast 172.16.7.255 vhid = 201 inet 172.16.0.233 netmask 0xfffff800 broadcast 172.16.7.255 vhid = 202 nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: active carp: MASTER vhid 201 advbase 1 advskew 1 carp: BACKUP vhid 202 advbase 5 advskew 100 laggproto loadbalance lagghash l2,l3,l4 laggport: ix1 flags=3D4<ACTIVE> laggport: ix0 flags=3D4<ACTIVE> vlan2: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> = metric 0 mtu 9000 options=3D303<RXCSUM,TXCSUM,TSO4,TSO6> ether 00:25:90:e3:71:f2 inet 10.11.11.201 netmask 0xffffff00 broadcast 10.11.11.255 inet6 fe80::225:90ff:fee3:71f2%vlan2 prefixlen 64 scopeid 0x6 inet 10.11.12.203 netmask 0xffffff00 broadcast 10.11.12.255 vhid = 12 nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: active vlan: 2 parent interface: lagg0 carp: BACKUP vhid 12 advbase 1 advskew 100 //mxb =20 On 2 apr 2014, at 09:35, mxb <mxb@alumni.chalmers.se> wrote: >=20 > Moving this to freebsd-pf. >=20 > On 31 mar 2014, at 22:21, mxb <mxb@alumni.chalmers.se> wrote: >=20 >>=20 >> Manually setting net.inet.carp.demotion brought BOTH VHIDs in desired = state. >> pfsync bulk update seems to not put everything back as it should. >>=20 >> lagg0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> = metric 0 mtu 9000 >> = options=3D8407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCS= UM,TSO4,TSO6,LRO,VLAN_HWTSO> >> ether 00:25:90:e3:71:f2 >> inet 172.16.0.234 netmask 0xfffff800 broadcast 172.16.7.255 >> inet6 fe80::225:90ff:fee3:71f2%lagg0 prefixlen 64 scopeid 0x5 >> inet 172.16.0.231 netmask 0xfffff800 broadcast 172.16.7.255 vhid = 201 >> inet 172.16.0.233 netmask 0xfffff800 broadcast 172.16.7.255 vhid = 202 >> nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> >> media: Ethernet autoselect >> status: active >> carp: MASTER vhid 201 advbase 1 advskew 1 >> carp: BACKUP vhid 202 advbase 5 advskew 100 >> laggproto lacp lagghash l2,l3,l4 >> laggport: ix1 flags=3D1c<ACTIVE,COLLECTING,DISTRIBUTING> >> laggport: ix0 flags=3D1c<ACTIVE,COLLECTING,DISTRIBUTING> >>=20 >>=20 >> On 31 mar 2014, at 20:42, mxb <mxb@alumni.chalmers.se> wrote: >>=20 >>>=20 >>> Hi list, >>>=20 >>> hopefully this is the right place to have my question regarding CARP = on 10-STABLE. >>>=20 >>> I have two nodes with following setup(node1): >>>=20 >>> lagg0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> = metric 0 mtu 9000 >>> = options=3D8407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCS= UM,TSO4,TSO6,LRO,VLAN_HWTSO> >>> ether 00:25:90:e3:71:f2 >>> inet 172.16.0.234 netmask 0xfffff800 broadcast 172.16.7.255 >>> inet6 fe80::225:90ff:fee3:71f2%lagg0 prefixlen 64 scopeid 0x5 >>> inet 172.16.0.231 netmask 0xfffff800 broadcast 172.16.7.255 vhid = 201 >>> inet 172.16.0.233 netmask 0xfffff800 broadcast 172.16.7.255 vhid = 202 >>> nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> >>> media: Ethernet autoselect >>> status: active >>> carp: BACKUP vhid 201 advbase 1 advskew 1 >>> carp: BACKUP vhid 202 advbase 5 advskew 100 >>> laggproto lacp lagghash l2,l3,l4 >>> laggport: ix1 flags=3D1c<ACTIVE,COLLECTING,DISTRIBUTING> >>> laggport: ix0 flags=3D1c<ACTIVE,COLLECTING,DISTRIBUTING> >>>=20 >>> net.inet.carp.preempt=3D1 on both nodes. as well as PSYNC as this: >>>=20 >>> pfsync0: flags=3D41<UP,RUNNING> metric 0 mtu 1500 >>> pfsync: syncdev: vlan22 syncpeer: 10.22.22.2 maxupd: 128 defer: = off >>>=20 >>> The problem is (if it is not clear from the ifconfig-output for the = lagg0) the state of VHID 201. >>> Node2 with advskew of 100 is currently MASTER, but it SHOULD NOT as = of setup. >>>=20 >>> Am I hitting a bug or doing something wrong? >>>=20 >>> I also have noted that after the pfsync bulk update the demotion = counter never setts to 0, but stays on 480, >>> thus preventing node1 become a MASTER 201(?).
