The default is 500 μs.DescriptionUse the service cbr command to specify the service type on the current PVC as constant bit rate (CBR).Use the undo service command to restore the default.The default service type of a PVC is UBR.You can use this command to set the service type and rate parameters for a PVC. The new configurationwill overwrite the old configuration.Setting of the argument cdvt-value does not take effect on the router.Related commands: service vbr-nrt, service vbr-rt, and service ubr.Examples# Create a PVC named aa, with the VPI/VCI of 1/101. system-view[Sysname] interface Atm 3/1/1[Sysname-Atm3/1/1] pvc aa 1/101# Specify the service type of the PVC as CBR, and set the PCR to 50000 kbps.[Sysname-atm-pvc-Atm3/1/1-1/101-aa] service cbr 50000
