Hi, I have a 1,6 Mbit/sec link and wish dedicate 50kbit for specific host. The another hosts in the network can use 160kbit. Look the configuration that I did:

hostname(config)# priority-queue outside
hostname(config-priority-queue)# queue-limit 122
hostname(config-priority-queue)# tx-ring-limit 2

hostname(config)# access-list shilova permit tcp any eq 80
hostname(config)# access-list shilova permit tcp any eq 443
hostname(config)# class-map shilova
hostname(config-cmap)# match access-list shilova

hostname(config)# policy-map QoS_policy
hostname(config-pmap)# class shilova
hostname(config-pmap-c)# police input 50000 9000
hostname(config-pmap-c)# priority

hostname(config-pmap-c)# class class-default
hostname(config-pmap-c)# police input 160000 28000

hostname(config)# service-policy QoS_policy interface outside

The configuration is ok?

Follow this:

In the following example, non-voice traffic is policed to 256 kbps, whatever is left of the bandwidth is then left for voice traffic.

class-map voice_non_marked
description Match non-Marked VoIP (RTP) packets
match rtp 16384 16383
class-map inspection_default
match default-inspection-traffic
class-map voice_marked
description match Marked VoIP (RTP) packets
match dscp ef
class-map non_voice
  match any
policy-map VoIP
  description Send VoIP packets to Priority Queue
  class voice_non_marked
  class voice_marked
  class non_voice
   police 256000
