ubr [ pcr ]
Command introduced in JUNOSe Release 7.1.0.
ATM VC Class Configuration mode added in JUNOSe Release 7.3.0.
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.
