vbr-nrt

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.

Syntax: 

vbr-nrt pcr scr mbs
