Dell Networking OpenFlow Hybrid Overview
The following acronyms are used in this chapter.
The Dell Networking OpenFlow Hybrid feature implements a true OpenFlow
hybrid model as opposed to a 'ships-in-the-night' model. Packets may be
forwarded normally via bridging or routing for interfaces that do not have
flows installed. On interfaces with flows installed, packet forwarding proceeds
normally (except as noted herein) for non-matching flows. Dell Networking
OpenFlow Hybrid enables the switch to be managed by a centralized
OpenFlow Controller using the OpenFlow protocol. Dell Networking
OpenFlow Hybrid is not supported in stacking deployments. Remove all stack
members prior to enabling Dell Networking OpenFlow Hybrid.
Dell Networking partially supports the OpenFlow 1.0 and OpenFlow 1.3
standards. The Dell Networking OpenFlow Hybrid switch contains
OpenFlow agent version 2.3.0 from the Open vSwitch (OVS) project. The
Open vSwitch code is licensed under the Apache 2 license. The OpenFlow
agent has been validated with the Helium release of OpenDaylight (ODL).
