Types

type Bridge

NewOVSBridge creates and returns a new OVSBridge struct.

func (*OVSBridge) AddOVSOtherConfig 

func (br *OVSBridge) AddOVSOtherConfig(configs map[string]interface{}) Error

AddOVSOtherConfig adds the given configs to the "other_config" column of the single record of the "Open_vSwitch" table. For each config, it will only be added if its key doesn't already exist. No error is returned if configs already exist.

func (*OVSBridge) Create 

func (br *OVSBridge) Create() Error

Create looks up or creates the bridge. If the bridge with name bridgeName does not exist, it will be created. Openflow protocol version 1.0 and 1.3 will be enabled for the bridge.

func (*OVSBridge) CreateInternalPort 

func (br *OVSBridge) CreateInternalPort(name string, ofPortRequest int32, externalIDs map[string]interface{}) (string, Error)

CreateInternalPort creates an internal port with the specified name on the bridge. If externalIDs is not empty, the map key/value pairs will be set to the port's external_ids. If ofPortRequest is not zero, it will be passed to the OVS port creation.

func (*OVSBridge) CreatePort 

func (br *OVSBridge) CreatePort(name, ifDev string, externalIDs map[string]interface{}) (string, Error)

CreatePort creates a port with the specified name on the bridge, and connects the interface specified by ifDev to the port. If externalIDs is not empty, the map key/value pairs will be set to the port's external_ids.

func (*OVSBridge) CreateTunnelPort 

func (br *OVSBridge) CreateTunnelPort(name string, tunnelType TunnelType, ofPortRequest int32) (string, Error)

CreateTunnelPort creates a tunnel port with the specified name and type on the bridge. If ofPortRequest is not zero, it will be passed to the OVS port creation.

func (*OVSBridge) CreateTunnelPortExt 

func (br *OVSBridge) CreateTunnelPortExt(

	localIP string,
	remoteIP string,
	psk string,
	externalIDs map[string]interface{}) (string, Error)

CreateTunnelPortExt creates a tunnel port with the specified name and type on the bridge. If ofPortRequest is not zero, it will be passed to the OVS port creation. If remoteIP is not empty, it will be set to the tunnel port interface options; otherwise flow based tunneling will be configured. psk is for the pre-shared key of IPSec ESP tunnel. If it is not empty, it will be set to the tunnel port interface options. Flow based IPSec tunnel is not supported, so remoteIP must be provided too when psk is not empty. If externalIDs is not nill, the IDs in it will be added to the port's external_ids.

func (*OVSBridge) CreateUplinkPort 

func (br *OVSBridge) CreateUplinkPort(name string, ofPortRequest int32, externalIDs map[string]interface{}) (string, Error)

CreateUplinkPort creates uplink port.

func (br *OVSBridge) DeleteOVSOtherConfig(configs map[string]interface{}) Error

DeleteOVSOtherConfig deletes the given configs from the "other_config" column of the single record of the "Open_vSwitch" table. For each config, it will only be deleted if its key exists and its value matches the stored one. No error is returned if configs don't exist or don't match.

func (*OVSBridge) DeletePort 

func (br *OVSBridge) DeletePort(portUUID string) Error

DeletePort deletes the port with the provided portUUID. If the port does not exist no change will be done.

func (*OVSBridge) GetOFPort 

func (br *OVSBridge) GetOFPort(ifName string) (int32, Error)

GetOFPort retrieves the ofport value of an interface given the interface name. The function will invoke OVSDB "wait" operation with 5 seconds timeout to wait the ofport is set on the interface, and so could be blocked for 5 seconds. If the "wait" operation times out or the interface is not found, or the ofport is invalid, value 0 and an error will be returned.

GetPortData retrieves port data given the OVS port UUID and interface name. nil is returned, if the port or interface could not be found, or the interface is not attached to the port. The port's OFPort will be set to 0, if its ofport is not assigned by OVS yet.

func (*OVSBridge) GetPortList 

func (br *OVSBridge) GetPortList() ([]OVSPortData, Error)

GetPortList returns all ports on the bridge. A port's OFPort will be set to 0, if its ofport is not assigned by OVS yet.
