Name

traffic-shape fecn-adapt — interface

Synopsis

traffic-shape fecn-adapt
no traffic-shape fecn-adapt

Configures

Traffic shaping on a frame relay subinterface

Default

Disabled

Description

This command enables the interface to reflect FECN bits as BECN bits, which notifies the sending DTE that it is transmitting at a rate too fast to handle.

Example

This configuration sets up traffic shaping with an upper limit of 128 Kbps and a lower limit of 64 Kbps. With the fecn-adapt command, our router reflects FECN packets as BECN packets.
