ElanBridgeManager

@Inject
public ElanBridgeManager(ElanConfig elanConfig,
                                 org.opendaylight.genius.interfacemanager.interfaces.IInterfaceManager interfaceManager,

                                 org.opendaylight.controller.md.sal.binding.api.DataBroker dataBroker)

Construct a new ElanBridgeManager.

Parameters:

elanConfig - the elan configuration

interfaceManager - InterfaceManager

southboundUtils - southboutUtils

dataBroker - DataBroker

Method Detail

isUserSpaceEnabled

public boolean isUserSpaceEnabled()

Is OVS running in userspace mode?

Returns:

true if the ovsdb.userspace.enabled variable is set to true

isOvsdbNode

public boolean isOvsdbNode(org.opendaylight.yang.gen.v1.urn.tbd.params.xml.ns.yang.network.topology.rev131021.network.topology.topology.Node node)

Is the Node object an OVSDB node.

Parameters:

node - unidentified node object

Returns:

true if the Node is an OVSDB node

isIntegrationBridge

public boolean isIntegrationBridge(org.opendaylight.yang.gen.v1.urn.tbd.params.xml.ns.yang.network.topology.rev131021.network.topology.topology.Node node)

Is this Node the integration bridge (br-int).

Parameters:

node - unidentified noe object

Returns:

true if the Node is a bridge and it is the integration bridge

isBridgeNode

public boolean isBridgeNode(org.opendaylight.yang.gen.v1.urn.tbd.params.xml.ns.yang.network.topology.rev131021.network.topology.topology.Node node)

Is this node a bridge.

Parameters:

node - unidentified node object

Returns:

true if this node is a bridge

processNodePrep

public void processNodePrep(org.opendaylight.yang.gen.v1.urn.tbd.params.xml.ns.yang.network.topology.rev131021.network.topology.topology.Node node,
                            boolean generateIntBridgeMac)

Advance the "preperation" of the OVSDB node. This re-entrant method advances the state of an OVSDB node towards the prepared state where all bridges and patch ports are created and active. This method should be invoked for the OVSDB node and the integration bridge node BUT IT IS SAFE TO INVOKE IT ON ANY NODE.

Parameters:

node - A node

generateIntBridgeMac - whether or not the int bridge's mac should be set to a random value
