programVpnToScfPipeline

public void programVpnToScfPipeline(String vpnName,
                                    short tableId,
                                    long scfTag,

                                    int addOrRemove)

Programs the necessary flows in LFIB and LPortDispatcher table so that the packets coming from a given VPN are delivered to a given ServiceChain Pipeline.

Parameters:

vpnName - Name of the VPN. Typically the UUID

tableId - Table to which the LPortDispatcher table sends the packet to (Uplink or Downlink Subsc table)

scfTag - Scf tag to the SCF to which the Vpn is linked to.

lportTag - VpnPseudo Port lportTag

addOrRemove - States if the VPN2SCF Pipeline must be installed or removed
