Frame-relay trafficshaping

Unanswered Question
Nov 14th, 2007


Just need a little clarification on the doubt that I have with FRTS.

1. Do we enable " frame-relay traffic shaping )under the FR interface only with legacy FRTS config.

2. With MQC FRTS we dont need the "frame-relay traffic shaping command" under the FR interface.

I think the answer is correct for both the questions, just need suggestion on that.

Thanks Guys.. Got the answer for that. Yes, its true for both the questions.

" Configuring traffic shaping using MQC and configuring traffic shaping using traditional FRTS commands are mutually exclusive. Traffic shaping cannot be configured on the same interface using both methods."

Hi Amit :)

1. Here is the output I get if I try to enable frame-relay traffic shaping under a serial interface with MQC configured.

Rack1R2(config-if)#frame traffic-shaping

Generic traffic shaping commands must be removed before enabling frame-relay

traffic shaping.

2. Correct, the following output from an interface configured with MQC FRTS

Rack1R2#sh policy-map interface

Serial1/0: DLCI 203 -

Service-policy output: FRTS

Class-map: class-default (match-any)

0 packets, 0 bytes
