Traffic-shape on 1711 Router

[abaghir]

Hello,

i'm having a problem with limiting my customer's bandwidth using 1711 router, beforw we used provide 1710 & 1720 router which was working fine, since these models are discontinued, now we are using 1711 but the problem is that when the traffic-shape is configured on the router the customer still can exceed the purchased bandwidth,

please note that we have tried more than three routers.

below is the command that configured on the router

interface FastEthernet0

traffic-shapre rate 128000

interface Vlan1

traffic-shapre rate 128000

Your help is highly appreciated...

Here is a note fix I saw on Cisco site. Hope this helps

•CSCef60411

Hardware flowcontrol failure in 1711->WIC-1AM transmit path.

When large bursts of data are transmitted by a 1711 router to a WIC-1AM line, packets may be dropped due to data overruns between the router async line and the modem's control processor. As a result, data throughput may be reduced and applications may fail.

Workaround: Configure generic traffic shaping on the async interface to throttle down the rate at which IOS transmits data to the modem. Note that this will impair the modem's transmission rate.

Example:

interface async 1

fair-queue

traffic-shape rate 16000 8000

Thnanks for your reply...

The mentioned note for the async interface, but i'm using ethernet and Vlan interfaces.

Are you using UBR, on your router, or R U using VBR on thr router with VBP you can adjust the peask traffic being sent out an interface with a CIR of #a certain number" , and the BR which should also be configured, hopefully this will help
