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.

• IPv4 and IPv6 flows cannot both be supported with iSCSI enabled on the

N4000. Disable iSCSI to support IPv4 and IPv6 flows simultaneously on

the N4000.

• The IPv6 destination address field is not supported on the N4000.

However, the IPv6 flow label is supported.
