Verifying the Traffic Parameter Configuration
Use the show atm vc command to verify the configuration of the traffic parameters for a PVC:
Router# show
atm vc

Purpose
Configures unspecified bit rate (UBR) quality of service (QoS) and peak cell rate
(PCR) for the PVC:
• output-pcr —Output PCR in kbps. The valid range is 48 to 149760 (OC-3) or
599040 (OC-12).
Configures the variable bit rate–nonreal time (VBR-nrt) QoS, the peak cell rate
(PCR), sustainable cell rate (SCR), and maximum burst cell size (MBS) for the PVC:
• output-pcr —Output PCR in kbps. The valid range is 48 to 149760 (OC-3) or
599040 (OC-12).
• output-scr —Output SCR in kbps. The valid range is 48 to PCR, and typically
is less than the PCR value.
• output-mbs —Output MBS in number of cells. The valid range is 1 to 65535,
depending on the PCR and SCR values. If the PCR and SCR are configured
to the same value, the only valid value for MBS is 1.
Configures the variable bit rate–real time (VBR-rt) QoS, and the PCR, average cell
rate (ACR), and burst cell size (BCS) for the PVC:
• pcr —PCR in kbps. The valid range is 48 to 149760 (OC-3) or 599040 (OC-12).
• scr —SCR in kbps. The valid range is 48 to PCR, and typically is less than the
PCR value.
• burst —Burst size in number of cells. The valid range is 1 to 65535, depending
on the PCR and SCR values. If the PCR and SCR are configured to the same
value, the only valid value for burst is 1.
Exits PVC configuration mode and returns to privileged EXEC mode.
