Chapter 1 Overview of the Cisco 3825 Mobile Wireless Edge Router New Features in Cisco IOS Release 12.4(16)MR1 atm mcpt-timers 1000 2000 3000 no atm ilmi-keepalive pvc 0/101 l2transport encapsulation aal0 cell-packing 28 mcpt-timer 3 xconnect 99.99.99.99 1101 pw-class l2tp ! 2. When more than one PVC needs to be mapped to a PW, configure the xconnect command under the subinterface mode to configure a N:1 VCC cell relay mode PW. All PVCs configured under this subinterface are mapped to the PW. A sample configuration is written as follows: interface ATM0/0/1.1 multipoint no snmp trap link-status atm cell-packing 28 mcpt-timer 3 xconnect 99.99.99.99 1200 pw-class l2tp pvc 1/35 l2transport encapsulation aal0 pw-pvc 2/135 ! pvc 1/36 l2transport encapsulation aal0 pw-pvc 2/136 ! pvc 1/37 l2transport encapsulation aal0 pw-pvc 2/137 ! ! ATM AAL5-SDU Mode ATM AAL5-SDU mode maps one AAL5 type PVC to a PW. Use the xconnect command under an AAL5 encapsulation type PVC to configure a AAL5-SDU mode PW. A sample configuration is written as follows: interface ATM0/0/1 no ip address load-interval 30 scrambling-payload atm mcpt-timers 1000 2000 3000 no atm ilmi-keepalive pvc 0/100 l2transport encapsulation aal5 xconnect 99.99.99.99 1100 pw-class l2tp ! Cell Packing Cell packing or concatenation supports Port, N:1 VCC cell, or 1:1 VCC cell mode. Cell packing can be configured with a parameter of a maximum number of cells and a parameter of cell packing timer. "atm mcpt-timers [timer1] [timer2] [timer3]" can be used under the interface mode to configure three cell packing timer values. Timer values are in microseconds, and the granularity is 1,000 microseconds, namely 1 millisecond. The timer value is referenced by the "atm cell-packing ..." and "cell-packing ..." commands.
