Hi

Outbound on the Spoke serial interface would guarantee 20kbps of traffic to Hub. To guarantee the return traffic you should apply it outbound at the HUB to each spoke site as well.

Yes.

Outbound on your CPE router, and make sure that the service provider does the same on their PE router.

Actually you can do classification input on your Eth inteface.

Hi,

You can bound the policy-map to the interface under the interface config mode using service-policy input/output

Hope it helps,

Re: Where to apply QOS ?

Hi Kerek,

Thanks for the reply, but my question is how to decide whether to apply the policy inbound or outbound on a interface.

If you take a Hub and Spoke environment with each spoke connected to the HUB using a 64 kbps leased line, and i want guarantee an bw of 20kbps for http traffic per branch , where should i applcy the policy ???

class-map match-any HTTP

match protocol http

policy-map HTTP

class HTTP

bandwidth 20

where should i apply this policy ???

HUB Serial inbound or outbound

SPOKE Serial inbound or outbound

I hope you got my question..

Hi Jon,

So I need to apply the policy both on Spoke Serial and Hub Serial in Outbound directions, Is that what you meant ?
