ubr

Description: 

In ATM VC Configuration mode, configures the unspecified bit rate (UBR) service category on an ATM PVC. Optionally, you can specify a peak cell rate (PCR). The ubr command is valid only for data PVCs; you cannot use this command for control (ILMI or signaling) PVCs. The no version restores the default service category, UBR without a PCR.

In ATM VC Class Configuration mode, configures the UBR service category as part of a VC class definition that you assign to an ATM data PVC. The no version restores the default service category, UBR without a PCR, in the VC class.
