from what I have read on the cisco site you can.

here is my proposed config.

Ip access-list extended custom_app (whatever the app is)

Permit tcp any any range 3001 3002 (depends on his port numbers)

Class-Map ?myownapp ?

Match access_group custom_app

Match access-group 100

Class-Map all-traffic

Match protocol IP -

Policy-map myapp

Class myownapp

Priority 400 (bandwidth)

Class all-traffic

Priority 3600 (rest of bandwidth)

Class class-defualt

Fair queue

Ip cef (I think this is already turned on)

Interface ? ntl outside interface ?

Service-policy myapp input

Access-list 100 permit ip (source)x.x.x.x (destination)x.x.x.x precedence critical

Mick,

Your CBWFQ with LLQ policy could only be applied outbound. Priority queueing is generally only used for voice and video. In your config all traffic is being priority queued which ends up being FIFO, or no QOS.

http://www.cisco.com/en/US/tech/tk543/tk545/technologies_q_and_a_item09186a00800cdfab.shtml

Queueing generally happens on outbound interfaces only. A router queues packets that are going out an interface. You can police inbound traffic, but usually you cannot queue inbound

Please rate helpful posts.

Hi,

Sorry Guys I probably should have made this clear.

I propose to put this policy on the internet facing router on the network which is managed by us and apply the policy for all traffic coming in to the network.

So will it work for me to do this config on the serial interface?

thanks for help here

Your policy will be ineffectual for inbound Internet traffic on your side of the Internet connection. Reason being, you're past the congestion point.

You need it on the ISP outbound (outbound to you) interface.

What I suggested was creating an artificial congestion point where you can manage the bandwidth. I also suggested placing it outbound on your LAN side, but it would also work inbound on your Internet side. It won't be as effective as your policy would be if that policy was placed on the ISP's router.

Hi All,

appologies for not replying sooner.

as it turns out this customer I am implementing this for already has QoS setup(on his internet facing router)

he has 2 serial interfaces configured in a mulitlink group.

so the want http traffic to get 10% of bandwith so if by adding a new class to the policy with bandwidth 10% that should do the trick yeah?
