Can't rate-limit or apply policy-map to SVI (VLAN interface)

Unanswered Question
Dec 22nd, 2007

We just upgraded our network core to a Cat 6506 w/SUP720-3B. We're running hybrid mode. We need to rate-limit our clients, each of which is setup on a separate VLAN. We can apply a rate-limit to the VLAN virtual interface, but the traffic isnt' actually rate limited. It's my understanding that this happens because after the first packets, everything is hardware switched, thus bypassing the rate-limits. We also tried setting up a policy-map to rate limit the interface. When we try to apply it, we get this:

TS-CORE1-L3(config-if)#service-policy input 512_input

MQC features are not supported for this interface

So, how do we rate-limit these clients?

I have this problem too.

I think we can configure rate limiting on SVI but we can't configure fancy L3 QOS (CBWFQ, LLQ, MQC) and Rate limiting on routed ports so verify your configuration.

The rate limit can be applied to the interface, but it doesn't actually work. A "show int vlan X rate-limit" doesn't show packets going through the interface. And, when running a speed test, the bandwidth isn't capped.
