Cisco best practices state that no more than 30% of interface bandwidth
be dedicated for the priority queue.
Thanks,
Steve

Why would you want to give 90% of a serial link to voice and 10% to
data, that is weird from my own view. That's about 1389.6kbps for voice
and 46kbps for each customer's data traffic .... (Assuming the serial
interface is 1544kbps)
There are so many ways to achieve this, this is one of them ...
!
class-map match-any VOICE
match dscp ef
match dscp af31
match protocol rtp audio
class-map match-all CLIENT1
match access-group name CLIENT1
match not dscp ef
match not dscp af31
match not protocol rtp audio
class-map match-all CLIENT2
match access-group name CLIENT2
match not dscp ef
match not dscp af31
match not protocol rtp audio
class-map match-all CLIENT3
match access-group name CLIENT3
match not dscp ef
match not dscp af31
match not protocol rtp audio
!
policy-map PRIORITY
class VOICE
priority percent 90
class CLIENT1
bandwidth percent 3
class CLIENT2
bandwidth percent 3
class CLIENT3
bandwidth percent 3
!
Int s0/0/0
max-reserved-bandwidth 100
!
Then configure ip extended access-lists CLIENT1, CLIENT2 and CLIENT3 to
respectively match any traffic destined for your individual clients
Many Thanks

I don't understand.
In my point of view, use PQ for voice traffic only, then exclude voice
traffic fron ACL 101 102 103 and use a normal service policy without
hierarchical MQC like this:
service policy qos
class voip
priority 90 ! Because max-reservable you set is 90%
class client1
bwd 33
class client1
bwd 33
class client1
bwd 33
Also, note that in your configuration below, you applied the qos only to
voice traffic and no qos is garanted for class-default!

Subject: qos problem
I have the following scenerio that I need some help . I have a link on
a serial interface that passes voice and data traffic to three clients.
My qos requirement is to give strict priority to all voice traffic
regardless to which client it is destined. I then have to give each
client one third of
any bandwidth that is still available. The following is my proposed
configuration.
class-map match-all rtptraffic
match protocol rtp voice
class-map match-all client1
match access-group 101
class-map match-all client2
match access-group 102
class-map match-all client3
match access-group 103
policy-map othertraffic
class client1
bandwidth percent 33
class client2
bandwidth percent 33
class client3
bandwidth percent 33
policy-map voice
class rtptraffic
priority percent 100
service-policy othertraffic
interface serial 1/0
max-reserved-bandwidth 90
service-policy output voice
