Chapter 9 Shaping Traffic
Verifying Traffic Shaping
Configuration Example for Traffic Shaping at the VC-Level and the VP-Level
Example 9-1 configures hierarchical shaping and shapes traffic at the VC-level and the VP-level. In the
example, shaping is enabled on PVC 1/36 on ATM interface 5/0/0.
Example 9-1 Configuring Traffic Shaping at the VC-Level and the VP-Level
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 Purpose
Router# show atm vp [vpi]
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.
Router# show atm vc [vcd] [interface
interface-number]
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.
Router# show controllers atm slot/module/port
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.
Router# show policy-map
Displays the configuration of all policy maps configured on the
router.
Router# show policy-map interface
Displays the configuration of all of the classes configured in all
of the policy maps that are attached to all of the router interfaces.
