Chapter 9 Shaping Traffic
Configuring Traffic Shaping
Shaping Traffic at the VC-Level and Virtual Path-Level
To shape traffic at the VC-level and simultaneously shape traffic at the virtual path (VP)-level, enter the
following commands beginning in global configuration mode:
Note These steps configure hierarchical shaping. Use these commands to shape an individual VC and then
shape the aggregate VCs into a VP.
Command Purpose
Step 1
Router(config)# interface atm
slot/module/port
Creates or modifies an ATM interface. Enters interface
configuration mode.
slot/module/port is the interface number.
Step 2
Router(config-if)# atm
over-subscription-factor factor
(Optional) Enables oversubscription on ATM virtual circuits and
specifies the factor by which the sum of the sustained cell rate
(SCR) values of all VCs in a tunnel can oversubscribe the tunnel’s
peak cell rate (PCR).
factor specifies the amount of oversubscription. Valid values are
from 1 to 500. The default value is 1, which indicates no
oversubscription.
Step 3
Router(config-if)# atm pvp vpi
[peak-rate] [cdvt]
Creates a permanent virtual path (PVP) used to multiplex (or
bundle) one or more virtual circuits (VCs).
vpi is the ATM network virtual path identifier (VPI) of the VC.
Valid values are 0 to 255. The vpi value is unique only on a single
link, not throughout the ATM network because it has local
significance only.
Note The number specified for the vpi must not already exist. If
the number specified is already being used by an existing
VC, the router rejects this command.
(Optional) peak-rate is the maximum rate in kbps at which the
PVP can transmit data. Valid values are 84 kbps to line rate. The
default is the line rate.
(Optional) cdvt is the cell delay variation tolerance (CDVT).
Step 4
Router(config-if)# interface atm
slot/module/port.subinterface
[point-to-point | multipoint]
Creates or modifies an ATM subinterface.
slot/module/port.subinterface is the number of the subinterface
that identifies the subinterface.
point-to-point indicates that the subinterface is a point-to-point
subinterface.
multipoint indicates that the subinterface is a point-to-multipoint
subinterface.
Step 5
Router(config-if)# pvc vpi/vci
Creates an ATM permanent virtual circuit (PVC) and enters ATM
virtual circuit configuration mode.
vpi is the virtual path identifier.
vci is the virtual channel identifier.
