Cisco QOS using Access Lists for Citrix and VOIP
Hello,
I am in need of some help developing a QoS policy for my MPLS utilizing access lists to map to specfic qos values. I need to prioritize my Avaya IP Office phone system which i believe uses dscp 46 for the call and dscp 34 for signaling.
Along with that I am looking for help in prioritizing my Citrix Xenapp traffic, I have Xenapp5 and Xenapp6 servers. Should this be done via port / protocol or via IP any suggestions?
The values my MPLS provider is said to support are:
EF-46 (Real Time)
AF-31(Critical)
AF-11(Priority)
Thank you.

They provide me with the class matching, I need to use access lists to classify the other traffic. Citrix, Avaya IPOffice VOIP, SQL Servers,
Attached is the class match, the provider has given me.
Attached is the class match, the provider has given me.
Class-map: DSCP-EF-CLASS (match-all)
dscp af41
Class-map: DSCP-AF31-CLASS (match-all)
dscp af42
Class-map: DSCP-AF11-CLASS (match-all)
dscp af43
Class-map: class-default (match-any)
dscp default
A typical scheme (the default scheme):
• Real Time QoS – Always prioritize over all other traffic; has a minimum guarantee of 100% bandwidth
• Critical QoS – Always yield to Real Time traffic; has a minimum guarantee of 50% of the excess bandwidth unused by Real Time traffic
• Priority QoS – Always yield to Real Time traffic; has a minimum guarantee of 30% of the excess bandwidth unused by Real Time traffic
• Standard QoS – Always yield to Real Time traffic; has a minimum guarantee of 20% of the excess bandwidth unused by Real Time traffic
