The pw-classkeyword binds the xconnect statement to a specific pseudowire class. Thepseudowire class then serves as the template configuration for allattachment circuits bound to it.NoteThe L2TPv3 session can also be provisioned manually. See the section“Manually Configuring L2TPv3 Session Parameters” for informationabout manually configuring the L2TPv3 session parameters.Configuring ATM AAL5 SDU Mode over L2TPv3 in VC Class Configuration ModeRestrictionsSUMMARY STEPSYou can create a VC class that specifies AAL5 encapsulation and then attach the VC class to an interface,subinterface, or PVC. Perform this task to create a VC class configured for AAL5 encapsulation andattach the VC class to an interface.This task requires Cisco IOS Release 12.0(30)S or a later release.1. enable2. configure terminal3. vc-class atm vc-class-name4. encapsulation aal55. end6. interface type slot/port7. class-int vc-class-name8. pvc [name] vpi/vci l2transport9. xconnect peer-router-id vcid encapsulation l2tpv376
