Frame-Relay Traffic shaping

I am investigating using the following config;

map-class frame-relay 256K_CIR_PVC

frame-relay traffic-rate 256000 512000

frame-relay adaptive-shaping interface-congestion 0

frame-relay fair-queue

And then this config on the main interface;

frame-relay traffic-shaping

frame-relay class 256K_CIR_PVC

My question is, will this cause a conflict between the rate-limit and the adaptive-shaping statements, or will the adaptive shaping use the rate limit as a reference.

Everyone I have talked to in the past steered me away from Adaptive-shaping.

Re: Frame-Relay Traffic shaping

Hello,

Greetings!

When you are using "rate-limit" command, you are using GTS (generic traffic shaping).

GTS is not recommened when you have Frame Relay application. Because GTS consumes CPU resources. And you apply them on the subinterface rather than using the map-class for unique DLCI.

GTS provides a mechanism to control the flow of outbound traffic on a particular interface while FRTS provides parameters that are useful for managing network traffic congestion.

Check this for configuration FRTS.
