Frame Relay QoS Inheritance

On Frame Relay interfaces, you can attach a service policy to the physical interface, an individual PVC,
or to both the physical interface and one or more PVCs. The following describes how Frame Relay traffic
inherits QoS policies:

map-class frame-relay Command

To attach a QoS service policy to a Frame Relay interface, PVC on a subinterface, DLCI, or map class,
use the map-class frame-relay command in global configuration mode. To remove a map class, use the
no form of the command. This command has no default behavior.

Description
The attachment of Frame Relay QoS service policies
feature was introduced on the router.
This feature was integrated into Cisco IOS
Release 12.0(25)S.
If you attach a service policy only to the physical interface, the aggregate of all PVCs is subject to
the physical interface's service policy.
If you attach a service policy only to individual PVCs and not to the physical interface, only the
individual PVC is subject to its attached service policy.
If you attach service policies to both the physical interface and individual PVCs, the aggregate of
all PVCs that do not have a service policy is subject to the physical interface's service policy. All
PVCs that do have a service policy are individually subject to their attached service policies.
If you attach a service policy to a Frame Relay point-to-point subinterface (either directly or using
a map class), the router applies the QoS service policy to the aggregate of all of the DLCIs
configured on the subinterface.
If you attach a service policy to an individual DLCI (either directly or using a map class), the router
only applies the QoS service policy to the individual DLCI.
The name of the map class. The map-class-name can be a maximum of
40 alphanumeric characters.
