QoS on a Cat 6513 native IOS - voice/SAP/WWW/Mail

I am installing a campus network with 2 cat 4006 (sup III) and 2 cat 6513 with native IOS. I will be configuring L3 between the switches and will be running VoIP - I need to configure QoS , prioritise Voice , Mail and SAP. Is there a basic config that I can use to implement on the switches. All the links between the switches will be 2 gigabits. I will be sending 60 calls , 729 , 12k per call

Please advise - currently setup in a LAB , with the switches and Phillips PBX

Have you seen the AVVID qos Design guide

Basic concept for cat4k sup3/4 is

-> trust on the ingress port and mark the packets with DSCP of 46

--> Configure high priority queue (queue 3)

--> for non-voip traffic make sure it maps to Q2 and you can configure a share value for it so that you get a min-gaurantee

on the cat6k, trust dscp

--> default mapping would map the dscp to strict priority queue.

With gig links, you don't have to worry about reserving bandwidth. you should be fine.

let me know if you have any specific questions
