The OpenFlow 1.0 standard supports a single-table data forwarding path. Dell Networking switches support Open Vswitch proprietary extensions to enable the OpenFlow controller access to multiple forwarding tables. The OpenFlow 1.3 standard enables a multi-table data forwarding path. Dell Networking switches, however, support a single-table OpenFlow 1.3 data forwarding path. The Dell Networking OpenFlow feature has the following major functions: 1 Enabling Dell Networking OpenFlow Hybrid. 2 Deploying OpenFlow Configuration. 3 Interacting with the OpenFlow Controllers. 4 Deploying OpenFlow Controller Flows. 5 Collecting Port and Queue Status and Statistics. 6 Supporting OpenFlow Controller Group tables Enable Dell Networking OpenFlow Hybrid The OpenFlow feature can be enabled and disabled by the network administrator. Although Dell Networking OpenFlow Hybrid may be administratively enabled, it is not operational until the switch has an IP address. The OpenFlow feature can be administratively disabled at any time. After administratively disabling the feature, the network administrator must wait until the OpenFlow Feature is operationally disabled before re-enabling the feature. The administrator can allow the switch to automatically assign an IP address to OpenFlow or to specifically select which address should be used. The administrator can also direct the OpenFlow feature to always use the out-ofband interface. If the address is assigned automatically and the interface with the assigned address goes down, the switch selects another active interface if one is available. Dell Networking OpenFlow Hybrid becomes operationally disabled and re-enabled when a new IP address is selected. If the address is assigned statically, the OpenFlow feature comes up only when a switch interface with the matching IP address becomes active. 1644 OpenFlow
