Overview of the Cisco 3825 Mobile Wireless Edge Router
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.
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.
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.
PVC Mapping
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:
