Method Detail

triggerProbe

void triggerProbe(DeviceId deviceId)

Triggers an asynchronous probe of the specified device, intended to determine whether the device is present or not. An indirect result of this should be invocation of DeviceProviderService.deviceConnected(org.onosproject.net.DeviceId, org.onosproject.net.device.DeviceDescription) )} or DeviceProviderService.deviceDisconnected(org.onosproject.net.DeviceId) at some later point in time.

Parameters:

deviceId - ID of device to be probed

roleChanged

void roleChanged(DeviceId deviceId,
                 MastershipRole newRole)

Notifies the provider of a mastership role change for the specified device as decided by the core.

Parameters:

deviceId - device identifier

newRole - newly determined mastership role

isReachable

boolean isReachable(DeviceId deviceId)

Checks the reachability (connectivity) of a device from this provider. Reachability, unlike availability, denotes whether THIS particular node can send messages and receive replies from the specified device.

Parameters:

deviceId - device identifier

Returns:

true if reachable, false otherwise

changePortState

void changePortState(DeviceId deviceId,
                     PortNumber portNumber,
                     boolean enable)

Administratively enables or disables a port.

Parameters:

deviceId - device identifier

portNumber - port number

enable - true if port is to be enabled, false to disable
