fail_mode: optional string, either secure or standalone
When a controller is configured, it is, ordinarily,
responsible
for setting up all flows on the switch. Thus, if the
connection
to the controller fails, no new network connections can be
set
up. If the connection to the controller stays down long
enough,
no packets can pass through the switch at all. This
setting
determines the switch=E2=80=99s response to such a situation.=
It may
be
set to one of the following:
standalone
If no message is received from the controller for
three
times the inactivity probe interval (see
inactiv=E2=80=90
ity_probe), then Open vSwitch will take over
responsibil=E2=80=90
ity for setting up flows. In this mode, Open
vSwitch
causes the bridge to act like an ordinary
MAC-learning
switch. Open vSwitch will continue to retry
connecting
to the controller in the background and, when the
connec=E2=80=90
tion succeeds, it will discontinue its standalone
behav=E2=80=90
ior.
secure Open vSwitch will not set up flows on its own when
the
controller connection fails or when no controllers
are
defined. The bridge will continue to retry connecting
to
any defined controllers forever

Hi all,<br>
<br>
Two questions:<br>
1. Even without a controller the default OVS acts like L2 learning switch. =
Is this correct? Or I've miss configured something that it processes un=
matched packets.<br>
2. How can I switch off the default OVSd activity? I would like just to use=
ovs-ofctl.<br>
<br>
Thanks and Regards,<br>
Alexander.<br>
