Types

type Interface added in v1.4.0

type Interface struct {
	// contains filtered or unexported fields
}

func New added in v1.4.0

func New(execer exec.Interface, bridge string, minVersion string) (*Interface, error)

New returns a new ovs.Interface

func (*Interface) AddBridge added in v1.4.0

func (ovsif *Interface) AddBridge(properties ...string) error

AddBridge creates the bridge associated with the interface, optionally setting properties on it (as with "ovs-vsctl set Bridge ..."). If the bridge already existed, it will be destroyed and recreated.

func (*Interface) AddPort added in v1.4.0

func (ovsif *Interface) AddPort(port string, ofportRequest int, properties ...string) (int, error)

AddPort adds an interface to the bridge, requesting the indicated port number, and optionally setting properties on it (as with "ovs-vsctl set Interface ..."). Returns the allocated port number (or an error).

func (*Interface) DeleteBridge added in v1.4.0

func (ovsif *Interface) DeleteBridge() error

DeleteBridge deletes the bridge associated with the interface. (It is an error if the bridge does not exist.)

func (*Interface) DeletePort added in v1.4.0

func (ovsif *Interface) DeletePort(port string) error

DeletePort removes an interface from the bridge. (It is not an error if the interface is not currently a bridge port.)

func (*Interface) DumpFlows added in v1.4.0

func (ovsif *Interface) DumpFlows() ([]string, error)

DumpFlows dumps the flow table for the bridge and returns it as an array of strings, one per flow.

func (*Interface) GetOFPort added in v1.5.0

func (ovsif *Interface) GetOFPort(port string) (int, error)

GetOFPort returns the OpenFlow port number of a given network interface attached to a bridge.

func (*Interface) NewTransaction added in v1.4.0

func (ovsif *Interface) NewTransaction() *Transaction

NewTransaction begins a new OVS transaction. If an error occurs at any step in the transaction, it will be recorded until EndTransaction(), and any further calls on the transaction will be ignored.

func (*Interface) SetFrags

func (ovsif *Interface) SetFrags(mode string) error

type Transaction

type Transaction struct {
	// contains filtered or unexported fields
}

func (*Transaction) AddFlow

func (tx *Transaction) AddFlow(flow string, args ...interface{})

AddFlow adds a flow to the bridge. The arguments are passed to fmt.Sprintf().

func (*Transaction) DeleteFlows

func (tx *Transaction) DeleteFlows(flow string, args ...interface{})

DeleteFlows deletes all matching flows from the bridge. The arguments are passed to fmt.Sprintf().

func (*Transaction) EndTransaction

func (tx *Transaction) EndTransaction() error

EndTransaction ends an OVS transaction and returns any error that occurred during the transaction. You should not use the transaction again after calling this function.
