Good day
I'm trying to traffic shape a circuit I have currently it is set up to take the full T1 1536K what I wanted to do is shape that to only take 1M how or can someone point me to a doc that tells me how to do this? Thank you in advance!!!

You can do Frame-Relay Traffic Shaping (FRTS) or Generic Traffic Shaping (GTS) with Modular QoS CLI (MQC).
With FRTS, you have the ability to shape per PVC while with GTS, it treats the interface as a single interface. In other words, you can designated traffic to DLCI 101 without affecting DLCI 102.
Due to this limitation, it's often recommended to shape using FRTS vs GTS.
Can you provide your config and network topology ?

Sure basically I have a point to point connection. Here is the config on both ends:
Far end:
interface Serial0/0/0
bandwidth 1536
ip address 172.19.90.126 255.255.255.252
encapsulation frame-relay
no ip mroute-cache
no fair-queue
service-module t1 timeslots 1-24
frame-relay traffic-shaping
frame-relay map ip 172.19.90.125 121 broadcast
frame-relay lmi-type cisco
end
Near end(my end)
interface Serial0/0/0.138 point-to-point
description PVC to sfscitrt2
bandwidth 256000
ip address 172.19.90.125 255.255.255.252
no ip mroute-cache
no cdp enable
frame-relay class cit-fr-cmap
frame-relay interface-dlci 138
end
map-class frame-relay cit-fr-cmap
frame-relay cir 256000
frame-relay bc 32000
frame-relay be 160000
frame-relay mincir 128000
frame-relay adaptive-shaping becn
service-policy output cit-pmap-egress
I didn't see a map class on the far end
My goal is to stop this connection from taking
over the whole Frame T1. Whenever this connection burst up to the Full T1 I lose connectivity to 2 sites
Also to add I have a Frame T1 with 10 other connections on it not sure why we have a connection on a Frame T1 that can burst up to T1 speed but we do everthing else is 128k the second biggest connection is 512k

On this router, you implemented FRTS - which is great !
It's configured for 256kbps and mincir 128kbps, can we see the config from the router you want to change ?
Please, also indicate how much traffic you want allocated per DLCI.
01-17-2008 06:53 AM
On a public forum I'm not allowed to do so but
if you have a email address I can send it to you. I noticed that FRTS is only configured on my router(near end) but the remote end
I don't see anything configured.
01-17-2008 07:20 AM
Just mask the ip addresses and DLCI information. I just want to have a general idea of how the config looks like.
You need to configure FRTS on the hub and spokes. You've only posted the config from one of the spokes.

I don't see any subinterfaces and I don't see what circuit you want to allocate the bandwidth.
What I need for you is a breakdown on how you want to divide the T1 per DLCI.
01-17-2008 08:33 AM
Sorry this is the distant end all the subinterfaces are at my end(NEAR End)
The config is a lot longer so it will take a few
01-17-2008 09:58 AM
You have shaping enabled on this router but you have not applied any policy to it. Was that your intention ?

01-17-2008 10:07 AM
Not sure as I didn't configure this router but I think if I enable shaping on both ends and install the correct policy then I think I would be limit this PVC to 1 meg. All I really did was take the existing policy and chaged 1536000 to 1000000:
map-class frame-relay cit-fr-cmap
frame-relay cir 1000000
frame-relay bc 192000
frame-relay mincir 768000
frame-relay adaptive-shaping becn
01-17-2008 10:25 AM
Right, currently the router is shaping to 56kbps.
You can verify with the command show frame pvc [dlci]

Ok I know what I need to do now thanks for knocking off the cob webs I will give it a shot this weekend and we will see what happens. thank you for your help!!!!!
