Configuring Interface Service Category Support

You can configure which service categories connection admission control (CAC) allows on an interface.
You can configure interface service category support only on physical interfaces and shaped and
hierarchical logical virtual path (VP) tunnel interfaces.
Note For information on how to configure your physical and logical VP tunnel interfaces, see
"Configuring Virtual Connections."
The underlying service category for shaped and hierarchical VP tunnels is CBR. For VP shaped tunnels,
interface service category support can be used to configure a service category other than CBR for VCs
within the tunnel. For physical interfaces and hierarchical VP tunnels, all service category VCs (by
default) can migrate across the interface. However, you can use the interface service category support
feature to explicitly allow or prevent VCs of specified service categories to migrate across the interface.

configure for transported VCs, and a suggested transit VP service category for the tunnel.

occurs at the shaped tunnel, not in the transit VP.
This configuration is allowed on physical interfaces and shaped and hierarchical VP tunnel logical
interfaces.
On shaped VP tunnel logical interfaces, only one service category is permitted at a time. To replace
CBR with another service category on these interfaces, you must first deny the CBR service
category, then permit the chosen service category. To deny a service category, you must delete all
user VCs of that service category on the interface.
For ABR and UBR, only zero MCR is supported on VCs on a shaped VP tunnel.
