Configuring VC Weighting
Configuring VC Weighting on a Range of PVCs
To configure VC weighting on a range of PVCs, enter the following commands beginning in global
configuration mode:
Configuration Example for Configuring VC Weighting on a Range of PVCs
Example 15-8 shows how to configure a weight of 255 on the PVCs in the range of 1/32 to 1/00.
Example 15-8 Configuring VC Weighting on a PVC Range
Router(config)# interface atm 1/0/0.1 multipoint
Router(config-subif)# range pvc 1/32 1/00
Router(config-if-atm-range)# weight 255
Command Purpose
Step 1
Router(config)# interface atm
slot/subslot/port.subinterface
Selects an ATM subinterface. Enters subinterface
configuration mode.
Step 2
Router(config-subif)# range pvc start_vpi/vci
end_vpi/vci
Specifies an ATM PVC range.
start_vpi/vci specifies the first virtual path identifier/virtual
channel identifier pair in the PVC range.
end_vpi/vci specifies the last virtual path identifier/virtual
channel identifier pair in the PVC range.
Step 3
Router(config-if-atm-range)# 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).
