Who When What Removed Added
Hynek Mlnarik 2016-09-01 14:14:14 UTC Link ID OpenStack gerrit 355315
Doc Text Cause:
Fail mode on OVS physical bridges was not set, defaulting to standalone. This however means that when the ofctl_interface is set to native and the interface becomes unavailable (due to heavy load, ovs agent shutdown, network disruption), the flows on physical bridges can be cleared.

Consequence:
The physical bridge traffic is disrupted

Fix:
Set OVS physical bridge fail mode to secure

Result:
Flows are retained on physical bridges.

Fix:

Result:
Flows are retained on physical bridges.
Prior to this update, the `Fail` mode on OVS physical bridges was not set, defaulting to `standalone`. However, this meant that when `ofctl_interface` was set to `native`, and the interface became unavailable (due to heavy load, OVS agent shutdown, network disruption), the flows on physical bridges could be cleared.
Consequently, the physical bridge traffic was disrupted. With this update, the OVS physical bridge fail mode has been set to `secure`. As a result, flows are retained on physical bridges.
