Example 15-7 Configuring VC Weighting Using a VC Class Map
Router(config)# vc-class atm Business
Router(config-atm-vcc)# weight 20
Router(config-atm-vcc)# exit
Router(config)# interface atm 1/0/0.1

Router(config-if-atm-vc)# class-vc Business
Command Purpose
Step 1
Router(config)# vc-class atm name
Defines a VC class.
name is the name of the VC class.
Step 2
Router(config-atm-vcc)# weight weight-value
Specifies the weight value.
weight_value is the number of cells that a VC can send to
the VP tunnel before the SAR mechanism moves on to the
next VC. A high value has a higher VC priority in the VP
scheduler. Valid values are from 1 to 255 and 1 to 1000
(PRE3).
Note We recommend that you do not configure the
weight_value below 10 (PRE2).
Step 3
Router(config-atm-vcc)# exit
Exits ATM VC class configuration mode.
Step 4
Router(config)# interface atm
slot/subslot/port.subinterface point-to-point
Selects an ATM subinterface. Enters subinterface
configuration mode.
Step 5
Router(config-subif)# pvc vpi/vci
Selects an ATM PVC.
vpi/ is the virtual path identifier. If you do not specify a VPI
value and the slash character (/), the VPI value defaults to 0.
vci is the virtual channel identifier.
Step 6
Router(config-if-atm-vc)# class-vc vc-classname
Applies a VC class to the PVC.
