# vbr-nrt

#### Syntax

vbr-nrt pcr scr mbs

no vbr-nrt

#### Release Information

Command introduced in JunosE Release 7.1.0.
ATM VC Class Configuration mode added in JunosE Release 7.3.0.

#### Description

In ATM VC Configuration mode, configures the variable bit rate, nonreal time (VBR-NRT) service category on an ATM PVC. You must specify the peak cell rate (PCR), sustained cell rate (SCR), and maximum burst size (MBS). The vbr-nrt 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, unspecified bit rate (UBR) without a PCR.

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

#### Options

- pcr—Peak cell rate, in Kbps, in the range 0–149760 (for OC3 ATM modules) or 0–599040 (for OC12 ATM modules)
- scr—Sustained cell rate, in Kbps, in the range 0–149760 (for OC3 ATM modules) or 0–599040 (for OC12 ATM modules)
- mbs—Maximum burst size, in cells, in the range 0–16777215

#### Mode

ATM VC Configuration, ATM VC Class Configuration
