The frame-relay traffic-shaping command enables traffic shaping for all VCs defined on the
interface. The frame-relay class map-class-name command specifies the map class that is
applied to the interface or subinterface. If this command is applied to a main interface, all the
VCs on the interface's subinterfaces inherit the map class's properties. The actual properties for
the FRTS are defined with the map-class frame-relay map-class-name command and all the
map class subcommands. In Table 5-3, the traffic rate is specified with average and peak values.
Other possible traffic shaping commands that are configured under map-class frame-relay are
described in Table 5-3.

FRTS Traffic Shaping Commands Table 5-3

Command Description

frame-relay traffic-rate average [ peak ] Defines the traffic rate for the VC.

frame-relay adaptive-shaping { becn | foresight }}}} Enables dynamic traffic shaping based on

received BECNs or ForeSight. ForeSight is a
Cisco proprietary traffic control mechanism.
This command replaces frame-relay becn-
response-enable .

frame-relay custom-queue-list list - number Defines a custom queue list number to apply

to the VC.

frame-relay priority-group list-number Defines a priority group number to apply to

the VC to enable priority queuing. It applies
the priority list that was defined at the global
configuration level.
