Page 7: Configuring Openflow
Configuring OpenFlow Software-Defined Networking (SDN) was developed to meet the growing requirements of virtualization technologies and data networks. SDN uses software to separate controlling functions from data forwarding, and provides simple, flexible device operations and high extensibility. OpenFlow is the communication interface between a controller and network devices to implement SDN. With OpenFlow, you can perform centralized data forwarding management for physical and virtual devices. -

The table-miss flow entry wildcards all match fields (all fields omitted) and has the lowest priority 0. The table-miss flow entry behaves in most ways like any other flow entry. Group table The ability for a flow entry to point to a group enables OpenFlow to represent additional methods of forwarding. -
Page 11: Openflow Instance
OpenFlow instance You can configure one or more OpenFlow instances on the same device. A controller considers each OpenFlow instance as a separate OpenFlow switch and deploys forwarding instructions to it. In this chapter, an OpenFlow switch is the same as an OpenFlow instance, unless otherwise specified. Associated VLAN When an OpenFlow instance is associated with VLANs, the flow tables take effect on packets only within those VLANs. -
Page 12: Openflow Configuration Task List
To use LLDP together with OpenFlow, you must enable LLDP globally on OpenFlow switches. To prevent LLDP from affecting topology discovery of OpenFlow controllers, H3C recommends that you disable LLDP on ports of OpenFlow instances. For more information about LLDP, see Layer 2—LAN Switching Configuration Guide. -
Page 13: Creating Flow Tables For An Openflow Instance
To ensure correct traffic processing, assign an Ethernet interface to only one OpenFlow instance. • • When you activate an OpenFlow instance that is associated with non-existent VLANs, the system automatically creates the VLANs. Do not delete any of these VLANs after the OpenFlow instance is activated. -
