| This section shows the
different ways to define a map class for traffic shaping.
Traffic Shaping through Rate
Enforcement
Define the average and peak rates if
the data is being sent faster than the speed at which the
destination is receiving. If you define the average and peak rates
(in bits per second) that are allowed on VCs associated
with the map class, use the frame-relay traffic-rate average
[peak] command. .
Router(config-map-class)#frame-relay
traffic-rate average [ peak]
Traffic Shaping through Dynamic
Enforcement
Specify that the router dynamically
fluctuates the rate at which it sends packets, depending on the BECNs
that it receives if you want the sending router to adjust its
transmission rate based on the BECNs received. To select BECN as the
mechanism to which traffic shaping will adapt, use the frame-relay
adaptive-shaping becn command.
Note: The frame-relay
adaptive-shaping command replaces the frame-relay becn-response-enable
command.
Traffic Shaping through Queuing
Specify either a custom queue list or
a priority queue group to use on VCs associated with the map class
if you want to use Cisco queuing mechanisms to control traffic flow.
To specify a custom queue list, use
the frame-relay
custom-queue-list number command.
To specify a priority queue list, use
the frame-relay
priority-group number
command. The number is a required number assigned to the custom or
priority queue list. The command syntax for both of these commands
is described in Table .
