OpenFlow 1.0 Support

OpenFlow (OF) 1.0 [STD-1] is supported on the S4810, S4820T, S6000, and MXL switches.

NOTE: When of-instance is enabled with version 1.3, the OpenFlow 1.0 functionality is also supported.

Match Parameters and Supported Values

Using OpenFlow, you can transmit the switch’s ports and forwarding tables to the controller, allowing the controller to configure

forwarding entries on the switch. OpenFlow also allows the controller to insert control packets through the switch and to redirect any

missed flow packets from the switch to the controller.

The flows in OpenFlow allow the switch to match based on the following parameters and values. The software forwards the match results

out of one or more network ports, with the option to modify the packet headers.
