This is my first attempt in configuring the QoS, would appreciate if some one could help me with this
Issue:
IP-phone -->2960S ----> 6506E ----> 2811 --- > provider MPLS cloud ----->2811 --->C3548---->2960S-->ip phone

You could do something like the following:
class-map VOIP
match dscp ef
policy-map VOIP
class VOIP
priority percent 10
int fa0/0
description To WAN
service-policy output VOIP
HTH,

Thank you very much John,
can you please tell me, is the priority percent 10 means 10% of the bandwidth will be allocated for the voice
so for example 5mbps link the voice will have 0.5mbps , is my understanding correct
many thanks
cheers..

Yes and no. It's 10 percent of what the policy believes is the available bandwidth which may differ from actual available bandwidth.
Also the percentage, for LLQ is both guarantee and a possible bandwidth policer. This (LLQ) class's traffic is guaranteed to be dequeued first if its traffic is 10 % or less. For any of this (LLQ) class's traffic that exceeds 10% (also assuming there's queuing), the excess % traffic will be dropped.

Thank you Joseph,
So to be safe I should increase the percentage since my real time voice traffic is going to be on higher side, in otherwords if my voice traffic exceeds the 10% the calls would not be clean and clear
thanks again
cheers..
