[c-nsp] Q regarding QoS on 6500

I have a simple question regarding QoS on 6500.

My question is: how do I know what type of cards/interfaces I'm using
(Flex WAN, OCM-WAN, LAN), and what type of QoS they support.
I want to be able to determine just by looking at the card specs, like
thats done in hardware and you can only use mls type QoS etc.
Now its like I thiink thats that type of port that only supports x,
and I thiink thats a WAN port that supports y.

I found this article:

The 6500 does QoS in three places:

    * Software-based in the MSFC
    * Hardware-based (multi-layer switching-based) in the PFC
    * Software-based on some line cards


In the article there is a table listing what QoS features are
supported on what type of Interfaces etc.

I also found this:

For hardware-switched traffic, PFC QoS does not support the bandwidth,
priority, queue-limit, or random-detect policy map class commands. You
can configure these commands because they can be used for
software-switched traffic.
