Configuring the Xconnect Attachment Circuit for ATM Single Cell Relay VCMode over L2TPv3SUMMARY STEPSDETAILED STEPSThe ATM Single Cell Relay VC Mode over L2TPv3 feature maps one VCC to a single L2TPv3 session.All ATM cells arriving at an ATM interface with the specified VPI and VCI are encapsulated into a singleL2TP packet.The ATM Single Cell Relay VC mode feature can be used to carry any type of AAL traffic over thepseudowire. It will not distinguish OAM cells from User data cells. In this mode, PM and Security OAMcells are also transported over the pseudowire.Perform this task to enable the ATM Single Cell Relay VC Mode over L2TPv3 feature.1. enable2. configure terminal3. interface type slot/port4. pvc [name] vpi/vci l2transport5. encapsulation aal06. xconnect peer-ip-address vcid pw-class pw-class-nameStep 1Step 2Command or ActionenableExample:Router> enableconfigure terminalPurposeEnables privileged EXEC mode.• Enter your password if prompted.Enters global configuration mode.Step 3Step 4Example:Router# configure terminalinterface type slot/portExample:Router(config)# interface ATM4/1pvc [name] vpi/vci l2transportExample:Router(config-if)# pvc 5/500l2transportSpecifies the interface by type, slot, and port number, and enters interfaceconfiguration mode.Creates or assigns a name to an ATM PVC, specifies the encapsulation type onan ATM PVC, and enters ATM VC configuration mode.• The l2transport keyword indicates that the PVC is for Layer 2 switchedconnections.
