https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207701 Pushkar Kothavade <pushkarbk@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pushkarbk@gmail.com --- Comment #2 from Pushkar Kothavade <pushkarbk@gmail.com> --- Hi Team, After going through the issue specified here, I investigated this issue on FreeBSD 10 stable, Freebsd 10.2 release and FreeBSD HOL platforms by creating lagg and vlan interfaces. After investigation, problem statement is as follows: ************************* *** Problem Statement *** ************************* After machine boots up, when we create a vlan on Lagg interface, vlan interface takes the same MAC address as that of lagg interface. This works fine as expected. Now going further, when we add/delete members of lagg bundle, MAC address of the lagg bundle changes as expected. It is expected that vlan MAC should also get changed, when MAC of lagg interface changes, but it is not happening. This issue is present in only 10 stable. It is not present in HOL and 10.2 release. ************************* ******** Fix ************ ************************* https://reviews.freebsd.org/differential/diff/14418/ ************************* ***** Test Plan ********* ************************* #################### #### Before Fix #### #################### [Step-0] uname -a ** Output ** FreeBSD Host-XXX 10.3-PRERELEASE FreeBSD 10.3-PRERELEASE #2 r294978M: Thu Jan 28 16:46:33 IST 2016 amd64 [Step-1] ifconfig lagg1 create [Step-2] ifconfig lagg1 laggproto failover laggport le1 laggport le2 [Step-3] ifconfig vlan1 create [Step-4] ifconfig vlan1 vlan 1 vlandev lagg1 [Step-5] ifconfig ** Output ** lagg1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:0c:29:5b:6a:04 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier laggproto failover lagghash l2,l3,l4 laggport: le1 flags=1<MASTER> laggport: le2 flags=0<> vlan1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:0c:29:5b:6a:04 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier vlan: 1 parent interface: lagg1 [Step-6] ifconfig lagg1 -laggport le1 [Step-7] ifconfig ** Output ** lagg1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:0c:29:5b:6a:0e nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier laggproto failover lagghash l2,l3,l4 laggport: le2 flags=1<MASTER> vlan1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:0c:29:5b:6a:04 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier vlan: 1 parent interface: lagg1 ** Conclusion ** vlan1 MAC does not change, when Lagg1 MAC changes. ################### #### After Fix #### ################### [Step-0] uname -a ** Output ** FreeBSD Host-XXX 10.3-PRERELEASE FreeBSD 10.3-PRERELEASE #6 r296988: Fri Mar 18 08:30:25 IST 2016 amd64 [Step-1] ifconfig lagg1 create [Step-2] ifconfig lagg1 laggproto failover laggport le1 laggport le2 [Step-3] ifconfig vlan1 create [Step-4] ifconfig vlan1 vlan 1 vlandev lagg1 [Step-5] ifconfig ** Output ** lagg1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:0c:29:5b:6a:04 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier laggproto failover lagghash l2,l3,l4 laggport: le1 flags=1<MASTER> laggport: le2 flags=0<> vlan1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:0c:29:5b:6a:04 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier vlan: 1 parent interface: lagg1 [Step-6] ifconfig lagg1 -laggport le1 [Step-7] ifconfig ** Output ** lagg1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:0c:29:5b:6a:0e nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier laggproto failover lagghash l2,l3,l4 laggport: le2 flags=1<MASTER> vlan1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:0c:29:5b:6a:0e nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet autoselect status: no carrier vlan: 1 parent interface: lagg1 ** Conclusion ** vlan1 MAC changes, when Lagg1 MAC changes.
