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
