Page 8: 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. - Page 9 OpenFlow supports the following types of ports: • Physical port—Corresponds to a hardware interface of a switch, such as an Ethernet interface. A physical port can be either an ingress port or an output port. Logical port—Does not correspond to a hardware interface of a switch and might be defined by •...
- Page 10 Instructions—To modify the action set or pipeline processing. These include the following types: • Meter—Directs the packets to the specified meter to limit the rate of the packets. Apply-Actions—Applies the specified actions in the action list immediately. Clear-Actions—Clears all the actions in the action set immediately. Write-Actions—Modifies all the actions in the action set immediately.
- Page 11 Group table The ability for a flow entry to point to a group enables OpenFlow to represent additional methods of forwarding. A group table contains group entries. Figure 4 Components of a group entry A group entry contains the following fields: Group Identifier—A 32 bit unsigned integer uniquely identifying the group.

Page 12: 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 these VLANs. -
Page 13: 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 14: Configuring Flow Table Ids
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. To associate an OpenFlow instance with VLANs: Step Command Remarks Enter system view. -

Step Command Remarks Enter OpenFlow instance view. openflow instance instance-id controller mode { multiple | By default, the controller mode is Set the controller mode. single } multiple. Setting the maximum number of flow entries You can set the maximum number of flow entries that an extensibility flow table supports. When the maximum number is reached, the OpenFlow instance does not accept new flow entries for that table and sends a deployment failure notification to the controller. -

By default, MAC address learning is Disable MAC address enabled in the VLANs associated with an learning in the VLANs OpenFlow instance. -
Page 17: Configuring Controllers For An Openflow Switch
Configuring controllers for an OpenFlow switch Configuring controllers and main connections An OpenFlow switch supports up to 64 controllers. However, the OpenFlow channel between the OpenFlow switch and each controller can have only one main connection. The main connection processes control messages to complete tasks such as deploying entries, obtaining data, and sending information. -
