Interaction with OpenFlow Controllers
Dell EMC Networking OpenFlow Hybrid implements a subset of the
OpenFlow 1.0 protocol and a subset of the OpenFlow 1.3 protocol. Dell EMC
Networking OpenFlow Hybrid also implements certain enhancements to the
OpenFlow protocol to optimize it for the Data Center environment and to
make it compatible with Open vSwitch. Dell EMC Networking OpenFlow
Hybrid interacts with any OpenFlow controller that supports OpenFlow 1.0
or the OpenFlow 1.3 standards.

Dell EMC Networking OpenFlow Hybrid Principles of Operation
The Dell EMC Networking OpenFlow Hybrid OpenFlow implementation is
targeted for the data center market as opposed to the education market. As a
consequence of this design decision, some aspects of the OpenFlow 1.0/1.3
specifications are not supported, while extra features are added to enhance
the data center networking environment.
Key limitations are:
A single bridge instance.
A limited subset of supported flow actions.
The Dell EMC Networking OpenFlow Hybrid implements the following
behaviors:
1
The switch behaves as an OpenFlow-Enabled Hybrid switch. This means
that the switch can forward OpenFlow and normal Layer-2 and Layer-3
traffic on the same ports and the same VLANs at the same time. When the
controller adds flows, the ports mentioned in the match criteria or egress
