Shaping traffic to lower speed sites

I am trying to shape traffic from hub site to slower spokes sites. I want to stop the hub site trying to send at a greater rate than the spoke can accept. An example would be copying a 10m file from hub to spoke.

I have two examples below; example 1 gives a blanket shaping to all sites (no good).

example 2 or 3 is what I think I need? I am looking forward to your suggestions.

all sites Cisco 877s 12.4(24)T3

site a 1m

site b 512k

site c 768

example 1

class-map match-any VOICE

match  dscp ef

match  dscp cs3

match  dscp af41

match access-group name VOICE

match access-group name VOICE-CONTROL

class-map match-any RemoteSupport

match access-group name RDP

!

policy-map VOICEWAN

class VOICE

    priority 250

class RemoteSupport

    bandwidth 300

class class-default

    fair-queue

policy-map SHAPING_OUTBOUND

class class-default

    shape average 776000

  service-policy VOICEWAN

example 2

class-map match-all to-b

match access-group 122

class-map match-all to-c

match access-group 120

class-map match-any VOICE

match  dscp ef

match  dscp cs3

match  dscp af41

match access-group name VOICE

match access-group name VOICE-CONTROL

class-map match-any RemoteSupport

match access-group name RDP

class to-c

    shape average 768000

class class-default

    fair-queue

example 3

Re: Shaping traffic to lower speed sites

Couple of pointers if it helps:-

Example 1 is also good to go provided you give the spoke 2 more queues, ie inside the child policy.

It is always recommended to give EF a seperate LLQ.

Give a small queue for the Voice Control and another one for the Video it its there.

A mixture of examples 1 and 2 may be the ideal choice that you are looking forward to.

Hi, Can you give me an example? I am not sure how to give more queues.

Thanks
