Cat 6500 Sup 2T and 6848 line card QoS question

Hello,

 

I am trying to wrap my head around Cat 6500 QoS with the new Sup 2T and 6848 line card and the new more-MQC-like QoS.

 

I am working with a client that intends to connect some servers and even a few power users to a 6500 with Sup 2T and 6848.

 

I have examined the Smart Business Architecture LAN Configuration docs (6500 in Appendix D):

 

http://www.cisco.com/en/US/docs/solutions/SBA/August2012/Cisco_SBA_BN_LANConfigurationFilesGuide-Aug2012.pdf

 

and examined the 6500 Sup 2T whitepaper:

 

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_paper_c11-652042.html

 

and the 6500 software config guide QoS section:

 

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/15.1SY/config_guide/sup2T/qos_overview.html

 

And I still have a few questions.  The use of MQC-like language for Queuing is fairly understandable as it is similar to Cat 4500 with Sup6/7.  But where I am still a little confused is Ingress classification and marking.

 

For example, if I have a server or an end user directly attached to a 6848 port, and I want to classify inbound traffic using ACLs, class-maps and a policy-map, do I attach both a lan-queuing service policy AND an input service policy?

 

For example:

 

int g1/1

service-policy input qos-ACCESS

service-policy type lan-queuing input p_map_2q8t

service-policy type lan-queuing output p_map_1p3q8t

 

Best,
