The default number of ATM cells to be packed is the MTU of theinterface divided by 52.• mcpt-timer timer—(Optional) Specifies which timer to use. The mcpttimers are set using the mcpt-timers command. The default value is 1.Binds an attachment circuit to a Layer 2 pseudowire and enters xconnectconfiguration mode.Example:Router(config-if-atm-vc)#xconnect 10.0.3.201 888encapsulation l2tpv3Configuring the Xconnect Attachment Circuit for ATM AAL5 SDU Mode overL2TPv3The ATM AAL5 SDU Mode feature maps the AAL5 payload of an AAL5 PVC to a single L2TPv3session. This service will transport OAM and RM cells, but does not attempt to maintain the relativeorder of these cells with respect to the cells that comprise the AAL5 CPCS-PDU. OAM cells that arriveduring the reassembly of a single AAL5 CPCS-PDU are sent immediately over the pseudowire, followedby the AAL5 SDU payload.Beginning in Cisco IOS Release 12.0(30)S, you may choose to configure the ATM AAL5 SDU Modefeature in ATM VC configuration mode or in VC class configuration mode.To enable the ATM AAL5 SDU Mode feature, perform one of the following tasks:• Configuring ATM AAL5 SDU Mode over L2TPv3 in ATM VC Configuration Mode, page 75• Configuring ATM AAL5 SDU Mode over L2TPv3 in VC Class Configuration Mode, page 7674
