PurposeCommand or Action
Step 4
Configures unspecified bit rate (UBR) quality of service (QoS) and peak cell rate
(PCR) for the PVC:
Router(config-if-atm-vc)# ubr
output-pcr
Step 5
• 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:
Router(config-if-atm-vc)# vbr-nrt
output-pcr output-scr output-mbs
Step 6
• 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.
Step 7
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:
Router(config-if-atm-vc)# vbr-rt
pcr scr burst
Step 8
• 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.
Repeat Step 2 through Step 3 for
each PVC to be configured.
Step 9
Exits PVC configuration mode and returns to privileged EXEC mode.Router(config-if-atm-vc)# end
Step 10
Verifying the Traffic Parameter Configuration
Use the show atm vc command to verify the configuration of the traffic parameters for a PVC:
Router# show
