Chapter 14 Simultaneous Policy Maps
Configuring Simultaneous Policy Maps
Configuration Example for Attaching a Policy to an ATM VC with PPPoE Sessions
The following example shows how to attach a simultaneous policy map to an ATM VC over which
PPPoE sessions traverse the network. The policy map named pppoe_sess_output_policy is attached to
Virtual-Template1, which is applied to the BBA group named VRF_1. The BBA group is attached to the
PVC range 81/801 to 81/810 on subinterface ATM 2/0/0.81801.

Command Purpose
Step 1
Router(config)# interface atm number
[point-to-point | multipoint]
Creates or modifies a subinterface. Enters subinterface
configuration mode.
number is the slot, module, port, subinterface number of the
interface (for example, 4/0/1.10).
point-to-point indicates that the subinterface connects directly
to one endpoint.
multipoint indicates that the subinterface connects to multiple
endpoints.
Step 2
Router(config-subif)# range pvc
start-vpi/end-vpi start-vci/end-vci
Defines a range of ATM permanent virtual circuits (PVCs).
(Optional) start-vpi/ is the beginning value for a range of virtual
path identifiers (VPIs). In the absence of the "/" and a VPI value,
the VPI value defaults to 0. Valid values are from 0 to 255.
(Optional) end-vpi is the end value for a range of virtual path
identifiers (VPIs). In the absence of an end-VPI value, the
end-VPI value defaults to the start-VPI value. Valid values are
from 0 to 255.
start-vci/ is the beginning value for a range of virtual channel
identifiers (VCIs). Valid values are from 32 to 65535. You must
specify the slash mark (/).
end-vci is the end value for a range of virtual channel identifiers
(VCIs). Valid values are from 32 to 65535.
Step 3
Router(config-subif-atm-vc)# vbr-nrt
output-pcr output-scr output-mbs
Configures the variable bit rate-nonreal time (VBR-NRT)
quality of service (QoS).
output-pcr is the output peak cell rate (PCR), in kbps.
output-scr is the output sustained cell rate (SCR), in kbps.
output-mbs is the output maximum burst cell size, expressed in
number of cells.
Step 4
Router(config-subif-atm-vc)# encapsulation
aal5snap
Configures the ATM adaptation layer (AAL) and encapsulation
type for the PVC range.
Step 5
Router(config-subif-atm-vc)# protocol
pppoe
Specifies the tunneling protocol that a virtual private dialup
network (VPDN) subgroup is to use, in this case PPPoE.
