Configuration Example for Configuring the Weight of Multiple VCs
Example 15-12
same sustained cell rate (SCR), but has different weights configured. The PVCs with the higher weights
get higher priority in the VP scheduler. Therefore, the PVCs in the range of 1/40 to 1/60 with a weight
of 40 have higher priority than the other configured PVCs:

Example 15-12 Configuring the Weight of Multiple VCs
Router(config)# interface atm 1/0/0.1 point-to-point
Router(config-subif)# pvc 1/32
Router(config-if-atm-vc)# vbr-nrt 1024 512
Router(config-if-atm-vc)# weight 10
Router(config-if-atm-vc)# exit
Router(config-subif)# interface atm 1/0/0.2 point-to-point
Router(config-subif)# pvc 1/33
Router(config-if-atm-vc)# vbr-nrt 1024 512
Router(config-if-atm-vc)# weight 20
Router(config-if-atm-vc)# exit
Router(config-subif)# interface atm 1/0/0.3 point-to-point
Router(config-subif)# pvc 1/34
Router(config-if-atm-vc)# vbr-nrt 1024 512
Router(config-if-atm-vc)# weight 30
Router(config-if-atm-vc)# exit
Router(config-subif)# interface atm 1/0/0.10 point-to-point
Router(config-subif)# range pvc 1/40 1/60
Router(config-if-atm-range)# vbr-nrt 1024 512
Router(config-if-atm-range)# weight 40
Configuration Example for Configuring VC Weight Using a Bandwidth
Remaining Ratio
Example 15-13
the bandwidth remaining ratio command is configured in an hierarchical policy to assign a weight of
100 to the VC.

shows how to configure the weight for multiple PVCs. In the example, each PVC has the
PVC 1/34 with a weight of 30
PVC 1/33 with a weight of 20
PVC 1/32 with a weight of 10
shows how to configure VC weight using a bandwidth remaining ratio. In the example,
