Description Use the service vbr-rtcommand to set the service type of PVC to Variable Bit Rate - Real Time (VBR-RT) and specify the related rate parameters in the PVC view.

By default, the service type is UBR after creating a PVC.

You can use this command as well as the service ubr, service cbr and service vbr-nrtcommands to set the service type and rate-related parameters of a PVC. A newly configured PVC service type overwrites the existing one. This command is not applicable to ATM E1 interfaces.

Related command: service vbr-nrt,service ubr, and service cbr.

Example # Create a PVC named “aa” with the VPI/VCI value of 1/101.

<Sysname> system-view

[Sysname] interface atm 1/0

[Sysname-Atm1/0] pvc aa 1/101

#Specify the service type of the PVC as VBR-RT and set the peak cell rate of ATM to 100,000 kbps, the sustainable cell rate to 50,000 kbps, and the maximum burst size to 320 cells.
