Default
The service type of a PVC is UBR. The peak output rate of ATM cells equals to the maximum bandwidth
of the interface to which the PVC belongs.

Parameters
output-pcr: Specifies the peak output rate of ATM cells in kbps. For more information about the value
range, see Table 41.
output
-scr: Specifies the sustainable output rate of ATM cells in kbps. Its value ranges are the same as
those of the output-pcr argument, and its value equals to or is smaller than that of the output-pcr
argument.
output-mbs: Specifies the maximum burst size of ATM cells (maximum number of ATM cells that the output
interface can cache). The value range for this argument is 1 to 512. For ATM E3 interfaces, the value
range for this argument is 1 to 512.
Usage guidelines
You can use this command as well as the service cbr, service ubr, and service vbr-nrt commands to set
the service type and rate of a PVC. A newly configured PVC service type overwrites the existing one.
This command is not applicable to ATM E1 interfaces.
Examples
# Create a PVC named aa on interface ATM 2/4/0, specifying its VPI/VCI value as 1/101, service type
as VBR-RT, peak output cell rate as 100000 kbps, sustainable cell rate as 50000 kbps, and maximum
burst size as 320 cells.
