Cisco 10000 Series Router Quality of Service Configuration Guide

Virtual template interfaces and VAIs do not apply to routed bridge encapsulation (RBE) over ATM.

Both the virtual template and virtual connection must exist before a remote user initiates a session

to the router.

Cisco IOS Release 12.2(25)SX does not support the configuration of broadband aggregation (BBA)

groups using RADIUS. You must configure BBA groups manually.

You can only apply a QoS policy with queuing-related actions to a VC. Do not apply service policies

with class-based weighted fair queuing (CBWFQ) actions to a VAI using a virtual template. The

router supports queuing only when you apply the QoS policy to a VC.

You can apply a QoS policy without queuing-related actions to either a VC or a VAI, but not to both

at the same time.

You cannot use RADIUS to configure a QoS policy on the VC.

If you configure a QoS policy on a VC, the show policy interface vai command does not display

information to indicate that the VAI is subject to the VC service policy. However, if you apply a

policy directly to a VAI, the show policy interface vai command displays information about the

policy on the VAI.

The port must be in atm pxf queuing mode.

You cannot configure a service policy on a VC and on a session at the same time.
