Cisco 10000 Series Router Quality of Service Configuration Guide
12-6
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.
