By defining separate virtual circuits for different types of traffic and
specifying queuing and an outbound traffic rate for each virtual circuit,
you can provide guaranteed bandwidth for each type of traffic. By
specifying different traffic rates for different virtual circuits over the
same line, you can perform virtual time division multiplexing. By
throttling outbound traffic from high-speed lines in central offices to
lower-speed lines in remote locations, you can ease congestion and
data loss in the network; enhanced queuing also prevents congestion-
caused data loss.
Traffic shaping applies to both PVCs and SVCs.
To configure Frame Relay traffic shaping, perform these tasks:
z Enable Frame Relay Traffic Shaping on the Interface
z Specify a Traffic-Shaping Map Class for the Interfac
z Define a Map Class with Queuing and Traffic Shaping Parameters
z Define Access Lists
z Define Priority Queue Lists for the Map Class
z Define Custom Queue Lists for the Map Class
Enable Frame Relay Traffic Shaping on the Interface
In interface configuration mode, enable Frame Relay traffic shaping
on an interface to enable both traffic shaping and per-virtual circuit
queuing on all the interface's PVCs and SVCs:
frame-relay traffic-shaping
Specify a Traffic-Shaping Map Class for the Interface
If you specify a Frame Relay map class for a main interface, all the vir-
tual circuits on its subinterfaces inherit all the traffic shaping parame
ters defined for the class.
In interface configuration mode, specify a map class for the specified
interface:
frame-relay class map-class-name
You can override the default for a specific DLCI on a specific sub-
interface by using the
class virtual circuit configuration
command to assign the DLCI explicitly to a different class.
