Hi,

What you have tried is unsupported feature; only marking is supported on SVI, no queuing service-policy is supported on SVI.

HTH,

Hi Nikita,

I think the OP was trying to apply qos under SVI on software based router not hardware based platform. The link you provided is configuration guide for 3750; I am afraid that might not help here.

yes lei tan is right.

i was actually talking about a cisco 2800 ISR.

i really need your help here guys

Hi,

What's your objective? Can you apply qos on physical interface?

it would work on the physical interface but i'm restricted to one physical interface which is being used by the service provider equipment.

the other interface is faulty. there is a lot of unwanted traffic coming from within the LAN and i want to cap it.

Hi,

It sounds you want police the unwanted traffic; have you tried police instead of shape? Since policer does not queue the packet, I think you might be able to use policer under SVI.

thanks Lei.

i cannot seem to find sample configurations for the policer

all i can find still points to the same class based policing which involves the use of a "service-policy" command on the interface which of course cannot be applied to a SVI.

please can you post relevant sources of sample configs for the policer.

thanks
