### Q: What versions of OpenFlow does Open vSwitch support?
A: The following table lists the versions of OpenFlow supported by
each version of Open vSwitch:
Open vSwitch OF1.0 OF1.1 OF1.2 OF1.3 OF1.4 OF1.5
###============ ===== ===== ===== ===== ===== =====
1.9 and earlier yes --- --- --- --- ---
1.10 yes --- [*] [*] --- ---
1.11 yes --- [*] [*] --- ---
2.0 yes [*] [*] [*] --- ---
2.1 yes [*] [*] [*] --- ---
2.2 yes [*] [*] [*] [%] [*]
2.3 yes yes yes yes [*] [*]
[*] Supported, with one or more missing features.
[%] Experimental, unsafe implementation.
Open vSwitch 2.3 enables OpenFlow 1.0, 1.1, 1.2, and 1.3 by default
in ovs-vswitchd. In Open vSwitch 1.10 through 2.2, OpenFlow 1.1,
1.2, and 1.3 must be enabled manually in ovs-vswitchd. OpenFlow
1.4 and 1.5 are also supported, with missing features, in Open
vSwitch 2.3 and later, but not enabled by default. In any case,
the user may override the default:
- To enable OpenFlow 1.0, 1.1, 1.2, and 1.3 on bridge br0:
ovs-vsctl set bridge br0
protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13
- To enable OpenFlow 1.0, 1.1, 1.2, 1.3, 1.4, and 1.5 on bridge br0:
ovs-vsctl set bridge br0
protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13,OpenFlow14,OpenFlow15
- To enable only OpenFlow 1.0 on bridge br0:
ovs-vsctl set bridge br0 protocols=OpenFlow10
All current versions of ovs-ofctl enable only OpenFlow 1.0 by
default. Use the -O option to enable support for later versions of
OpenFlow in ovs-ofctl. For example:
ovs-ofctl -O OpenFlow13 dump-flows br0
(Open vSwitch 2.2 had an experimental implementation of OpenFlow
1.4 that could cause crashes. We don't recommend enabling it.)
[OPENFLOW-1.1+.md] in the Open vSwitch source tree tracks support for
OpenFlow 1.1 and later features. When support for OpenFlow 1.4 and
1.5 is solidly implemented, Open vSwitch will enable those version
by default. Also, the OpenFlow 1.5 specification is still under
development and thus subject to change.
