Builds a Flow to be programmed in a DPN's DMAC table. This method must be used when the MAC is located in an External Device (TOR). The flow matches on the specified MAC and 1) sends the packet over the CSS-TOR tunnel if SHFlag is not set, or 2) drops it if SHFlag is set (what means the packet came from an external tunnel)

Parameters:

dpId - DPN whose DMAC table is going to be modified

extDeviceNodeId - Hwvtep node where the mac is attached to

elanTag - ElanId to which the MAC is being added to

vni - the vni

dstMacAddress - The mac address to be programmed

displayName - the display name

Returns:

the flow

Installs a Flow in the specified DPN's DMAC table. The flow is for a MAC that is connected remotely in an External Device (TOR) and that is accessible through an external tunnel. It also installs the flow for dropping the packet if it came over an ITM tunnel (that is, if the Split-Horizon flag is set)

Parameters:

dpnId - Id of the DPN where the flow must be installed

extDeviceNodeId - the ext device node id

elanTag - the elan tag

vni - the vni

macAddress - the mac address

displayName - the display name

interfaceName - the interface name

Returns:

the dmac flows

Throws:

ElanException - in case of issues creating the flow objects

                                       throws ElanException

Installs or removes flows in DMAC table for MACs that are/were located in an external Elan Device.

Parameters:

dpId - Id of the DPN where the DMAC table is going to be modified

extNodeId - Id of the External Device where the MAC is located

elanTag - Id of the ELAN

vni - VNI of the LogicalSwitch to which the MAC belongs to, and that is associated with the ELAN

macAddress - the mac address

elanInstanceName - the elan instance name

addOrRemove - Indicates if flows must be installed or removed.

interfaceName - the interface name

Throws:

ElanException - in case of issues creating the flow objects
