Attaching Frame Relay QoS Service Policies
Feature History for Frame Relay QoS
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:
•
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.
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.
