Description Timothy Redaelli 2018-03-29 09:28:14 UTC
+++ This bug was initially created as a clone of Bug #1553627 +++

Description of problem:

Hi there,
I would like to ask to backport to all our supported OVS versions the following upstream commit.
https://github.com/openvswitch/ovs/commit/6f50056c4fe7e1ae2eb3baa9086796686dc6e0e7

https://patchwork.ozlabs.org/patch/845107/

As described in the commit comment, if a switch member of the lag goes down (for a reboot, maintenance etc) LACP goes down as well.

Version-Release number of selected component (if applicable):
This issue applies to any OVS with the exception of 2.9 and master.
This issue definitely impacts kernel datapath. I'm not sure about netdev.

How reproducible:
Setup a plain OVS, create an LACP bond, shutdown/reboot a physical switch.

Actual results:
OVS LACP goes down and it stops forwarding any data until the original member is back to normal.

Expected results:
LACP is designed for not going down.
