frame-relay adaptive-shaping





frame-relay adaptive-shaping {becn  | foresight }

no frame-relay adaptive-shaping


Syntax Description:


Enables rate adjustment in response to BECN.


Enables rate adjustment in response to ForeSight messages.

Command Description:

Use the frame-relay adaptive-shaping map-class subcommand to select the type of backward notification you want to use. Use the no form of the command to disable backward notification.

This command replaces the frame-relay becn-response-enable command, which will be removed in a future Cisco IOS release. If you use the frame-relay becn-response-enable command in scripts, you should replace it with the frame-relay adaptive-shaping command.

The frame-relay adaptive-shaping command configures a router to respond to either BECN or ForeSight backward congestion notification messages.

Include this command in a map-class definition and apply the map class to either the main interface or to a subinterface.


This example shows the map-class definition for a router configured with traffic shaping and Router ForeSight enabled.
