Different Port QoS on C6.5K VS-S720-10G Module with VSL

Hello,

I've got a question regarding different QoS policies on a VS-S720-10G Module which also hosts a VSL.

Setup: - 2 x Catalyst WS-C6509-E (IOS 12.2(17r)SX7) with a VS-S720-10G Supervisor Engine and a VS-F6K-PFC3C submodule as VSS - The Te2 interface is used as a Virtual Switch Link (the other is located on a WS-X6708-10GE module), Te3 is used as a L3 interface. - Gi1 is used for Fast Hello Dual-Active Detection in the VSS - Gi2 and Gi3 are not in use.

I would like to use Gi2 as a L3 interface with a set of QoS rules (WRR). From my understanding a special QoS is needed for the VSL ("no mls qos channel-consistency") and the cisco documentation states, that "Port-based queue types are determined by the ASICs that control the ports"[1]. The only thing I could find out is that "The Supervisor Engine 720 features the PFC3, which is equipped with a high-performance ASIC complex"[2].

I'd like to know if the Gi2 interface is served by another ASIC and therefore can be configured with different Qos rules from the VSL interface Te1.

One more thing I found: "12.2(33)SXHI will allow diverse QOS configuration on the unused 10G port of Sup720-10G".[3] So would maybe upgrading to 12.2.(33) help? Or does this only affect the 10G ports?

Thanks for any advice!

Sam
