How to Configure ATM Class of Service
Configuring Unspecified Bit Rate Plus
Complete the following steps to configure Unspecified Bit Rate Plus (UBR+) QoS class for an ATM
permanent virtual circuit () and to specify the bandwidth on the Cisco ASR 901 series router.
SUMMARY STEPS

DETAILED STEPS
Step 4
pvc
VPI/VCI
l2transport
Example:
Router(config-if)# pvc 100/12
l2transport
Specifies the VPI and VCI of the PVC and configures the PVC in
layer 2 transport mode.
• l2transport is an optional field.
Step 5
ubr
rate
Example:
Router(config-if-atm-vc)# ubr 16000
Configures the UBR QoS class for an ATM permanent virtual circuit
(PVC) and specifies the bandwidth. By default a value is set to UBR
ATM class of service with the rate equal to the bandwidth of the
IMA interface, which in turn is a product of the number of active
IMA links and the bandwidth of each link.
• rate—Peak cell rate in Kbps.
