Traffic Shaping on a pair of 1700

[Fuzznuts]

I have a pair of 1721 at either end of a 2mb p2p line we use an avaya ip phone system for or telecomms. I am trying to implement traffic shaping so that the phones dont go all mental when some one downloads a large file off the internet or sends a large file between sites. the internet one isnt too much of a problem as i throttle it at the firewall.

currently my conf look like this

!
version 12.2
service config
service timestamps debug datetime msec
service timestamps log uptime
no service password-encryption

basically i am trying to limit all traffic other than that from 10.0.0.29 to 200k/s 10.0.0.29 is the avaya unit this will leave around 25/ks for the phones which is more than enough.

As you can see i am just fiddling with speeds of the shaping but it seems to shape all traffic if i put the access-list 105 first and shapes none if i place the access-list 104 first or if am going about this enitrely the wrong way then plase point me in the right direction.

I have read the cisco docs but they are very dry and tbh a bit over my head.

any help much appreciated.

Cheers

What you really want to use is LLQ (Low Latency Queing), that way the voice will always get priority over the regular traffic, the internet traffic will be serviced on best effect when there is voice.

Check it on Cisco website.....

BTW..what values did you want for the voice and the rest of the traffic, you numbers don't quite seem to match up.
