Chapter 1 Overview of the Cisco 3825 Mobile Wireless Edge Router New Features in Cisco IOS Release 12.4(16)MR1 Cell Packing PVC Mapping 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. The sample below configures cell packing for ATM port modes. It specifies a maximum number of cells as 28 and a cell packing timer as 3,000 microseconds. interface ATM0/0/0 no ip address scrambling-payload atm mcpt-timers 1000 2000 3000 no atm ilmi-keepalive atm cell-packing 28 mcpt-timer 3 xconnect 99.99.99.99 100 encapsulation mpls sequencing both pvc 1/35 l2transport encapsulation aal0 ! pvc 1/36 l2transport encapsulation aal0 ! pvc 1/37 l2transport encapsulation aal0 ! The sample below configures cell packing for the N:1 VCC cell relay mode PW. It specifies a maximum number of cells as 20 and a cell packing timer as 4,000 microseconds. interface ATM0/0/1 no ip address load-interval 30 scrambling-payload atm mcpt-timers 2000 3000 4000 no atm ilmi-keepalive pvc 0/101 l2transport encapsulation aal0 cell-packing 20 mcpt-timer 3 xconnect 99.99.99.99 1101 encapsulation mpls sequencing both The pw-pvc command configures PVC mapping or rewrites for PW-configured PVCs. It specifies the PW-side vpi/vci value used in sending and receiving PW packets for specified PVCs. The following example illustrates the use of the pw-pvc command: pvc 0/40 l2transport encapsulation aal0 pw-pvc 1/40 xconnect 1.1.1.1 40 encapsulation mpls OL-15667-03 Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide 1-19
