Is there a way to make hierarchical traffic shaping work on VLAN interface on Cat6500 with SUP720? I understand that traffic shaping is not supported by PFC, so we issued "no mls switching" command and from "show policy-map interface" I see that packets are passing through. However, it seems that no shaping is done, as the policy is passing 2 mbps of traffic even though I have set "shape average 512000" on it.

Shaping is not supported on VLAN interfaces. Configure a policer instead

I'm afraid policing is not an option. :(
We need to shape the traffic and then do LLQ inside.
Is there any way to force traffic to be shaped in software by MSFC?

No. It cannot be. LLQ is only supported on WAN interfaces. For ethernet/VLAN interfaces, you will need to use PFC based QoS.
