Command Mode OpenFlow Configuration User Guidelines This command configures the switch to select an IP address from a particular type of interface. The selected IP address is used as the local end-point of the IP connections to the OpenFlow controllers. The administrator can allow the switch to automatically assign an IP address to the OpenFlow feature or to specifically select which address should be used. The administrator can also direct the OpenFlow feature to always use the out-of-band interface. When in auto mode, the switch selects an IP address from an interface in this order: 1 The loopback interfaces. 2 The routing interfaces. 3 The out-of-band interface. Once the IP address is selected, it is used until the interface goes down or the OpenFlow feature is disabled or, in case of automatic address selection, a more preferred interface becomes available. Only IPv4 addresses are supported for OpenFlow controllers. Changing the mode causes the connections to controllers to be dropped, and if properly configured, re-established. If the switch is configured in static mode, OpenFlow will remain operationally disabled until a static IPv4 address is configured, the IPv4 address matches exactly an IPv4 address on a VLAN interface, and the VLAN interface is operationally enabled. If the OOB interface is manually selected as the OpenFlow IP address then the Open Flow feature becomes enabled immediately, even if there is no IP address assigned to the service port. If the OOB interface is used to connect to the OpenFlow controllers, the controllers should be on the same subnet as the OOB interface. Data Center Technology Commands 1263
