OpenFlow Configuration

G8264 Command Reference for ENOS 8.4
OpenFlow is an open interface used to control the forwarding plane in compatible
switches and routers remotely, from an external controller. The RackSwitch G8264
can function as either a Hybrid or OpenFlow‐only switch:
 In Hybrid mode (default), an OpenFlow pipeline can be set up to run in parallel
to the normal Ethernet switching pipeline. The two pipelines are completely
separate, each with its own dedicated ports and confined packet flows.
In OpenFlow‐only mode, the normal Ethernet switching capabilities are

disabled, and the RackSwitch G8264 behaves as a pure OpenFlow switch.
The following table describes the OpenFlow configuration options.
