6509-E Sup2T
Anyone have experience with the Sup2T 12.2SY/15.1 and QoS? I'd like to pick your brain a bit if possible.
Trying to plan for QoS, but seems the syntax has changed a bit.

So I was able to create a queuing policy after reading everything I could find on the Sup2t, but unfortunately my hardware doesn't support class maps matching DSCP on Gig interfaces.
Can someone enlighten me as to the best practices when using CoS vs DSCP? I'm thinking I may just need to classifiy via CoS everywhere and DSCP only across Serial links.
Forgive my ignorance... -

Well, I haven't received any feedback so I can only assume that the Sup2T is just too new. See the lack of documentation on Cisco's site, I kind of expected that.
Anyway, I was able to get a working config between the 6509 and some 3750s. Saturated the links and trickled some VoIP and Video traffic across it without a single "interesting traffic" drop. I have attached the topology of my lab and the configs of the switches I was able to get working (after many many head scratching moments). I still have to lab up the other portions of my topology, but its a start.
Oh, and does anyone know if there is a command equivalent to "show mls qos interface <interface> stat" for the Sup2T? The closest I could find was "show queueing interface <interface> details" but it just doesn't give was the other command does. I want to be able to see CoS/DSCP ingressing and egressing the ports...

Kind of curious. What did you pay for the SUP-2T? It is a sweet piece of hardware but I can't imagine too many private companies would have a need for that class of hardware. Are you using 10G switch modules at all? Anything else? 40G? I just outfitted a pair of 6509-E with dual Sup-720-3bxl and it should be more than I need for quite a while. -

Price, couldn't disclose that information without getting myself in trouble. 10G, yes and lots of it. 40/100G, not yet but probably soon.
Setting ourselves up for the future... -

It sucks that Cisco didn't make them capable of holding more routes than the 720-3BXL. The IPv4 routing table size is going to be huge soon.
