Shaping Traffic
Configuration Example for Traffic Shaping at the VC-Level and the VP-Level
Example 9-1
example, shaping is enabled on PVC 1/36 on ATM interface 5/0/0.
Example 9-1
Router(config)# interface atm 5/0/0
Router(config-if)# atm over-subscription-factor 50
Router(config-if)# atm pvp 1 1000 cdvt 600
Router(config-if)# pvc 1/36
Router(config-atm-vc)# vbr-nrt 1000 512
Router(config-atm-vc)# encapsulation aal5mux ppp Virtual-Template1
Router(config-atm-vc)# queue-depth 288 256
Router(config-atm-vc)# exit
Verifying Traffic Shaping
To verify the configuration of traffic shaping, enter any of the following commands in privileged EXEC
mode:
Command
Router# show atm vp [vpi]
Router# show atm vc [vcd] [interface
interface-number]
Router# show controllers atm slot/module/port
Router# show policy-map
Router# show policy-map interface

configures hierarchical shaping and shapes traffic at the VC-level and the VP-level. In the
Configuring Traffic Shaping at the VC-Level and the VP-Level
Purpose
Displays the statistics for all virtual paths (VPs) on an interface
or for a specific VP.
(Optional) vpi is the ATM network virtual path identifier (VPI)
for the permanent virtual path (PVP). Valid values are from 0 to
255. The VPI is an 8-bit field in the header of the ATM cell.
Displays all ATM permanent virtual circuits (PVCs) and traffic
information.
(Optional) vcd specifies a virtual circuit. When you specify vcd,
information about only the specified virtual circuit displays.
(Optional) interface interface-number is the interface number or
subinterface number of the PVC. When you specify interface
interface-number, information about all of the PVCs on the
specified interface or subinterface displays.
Displays ATM controller status.
Use this command to ensure that packets are not being discarded
due to internal buffer exhaustion.
slot/module/port is the interface number.
Displays the configuration of all policy maps configured on the
router.
Displays the configuration of all of the classes configured in all
of the policy maps that are attached to all of the router interfaces.
