Chapter 19 Configuring Quality of Service for PVC Bundles
ATM PVC Selection
• The Cisco 10000 router does not support automapping of PVCs or variable bit rate-real-time
(VBR-rt) for PVCs.
• The Cisco 10000 router supports aal5snap and aal5mux encapsulation types for PVCs and
multipoint and point-to-point subinterfaces.
VC Selection
• You can map one or multiple precedence or MPLS EXP levels to a single PVC; however, you cannot
map multiple PVCs to one precedence or MPLS EXP level.
• A PVC bundle does not come up until you configure all of the precedence or MPLS EXP levels in
the bundle.
• If you attach a VC class with bundle attributes to a PVC that is not configured as a member of a
PVC
bundle, the Cisco 10000 router ignores the bundle attributes.
ATM Inverse ARP
• You can enable or disable inverse ARP for the PVC bundle but not for individual PVCs in the bundle.
• ATM inverse ARP for IP uses the PVC configured with precedence level 6.
• Inverse ARP for protocols other than IP (for example, IPX) is disabled by default unless you
explicitly configure it in the PVC bundle.
Packet Forwarding
• The Cisco 10000 router does not support fast switching of IP packets.
Configuring ATM Bundles
You can configure ATM bundles either directly or by associating a VC class with the bundle.
To configure ATM bundles, perform the following configuration tasks:
• Creating an ATM Bundle Directly, page 19-18
• Creating an ATM Bundle Using a VC Class, page 19-20
• Adding an ATM PVC to a PVC Bundle, page 19-23
Creating an ATM Bundle Directly
The router applies the parameters you configure in ATM bundle configuration mode to the PVC bundle
and to all of the bundle members. These parameters supersede the parameters that you apply by
associating a VC class with the bundle. Parameters that you apply to an individual PVC supersede the
parameters that you apply to the bundle.
To create a PVC bundle directly, enter the following commands beginning in global configuration mode:
Command Purpose
Step 1
Router(config)# interface atm
slot/module/port[.subinterface]
Creates or modifies an interface or subinterface. Enters interface
or subinterface configuration mode.
Step 2
Router(config-subif)# mpls ip
(Optional) Enables MPLS forwarding of IPv4 packets along
normally routed paths. You must configure this command if you
configure MPLS EXP-based PVC selection.
