Cristiano,

Tenho um exemplo de configuracao aqui:

1) Listas de acesso para MATCH de trafego:

no ip access-list extended MPLS_ACL_MULTIMIDIA
ip access-list extended MPLS_ACL_MULTIMIDIA
  permit ip any 10.180.201.0 0.0.0.255
  permit ip any 10.180.204.0 0.0.0.255
  permit ip any 10.180.205.0 0.0.0.255
  permit ip any 10.180.206.0 0.0.0.255
  permit ip any 10.180.207.0 0.0.0.255
  permit ip any 10.180.208.0 0.0.0.255
  permit ip any 10.180.209.0 0.0.0.255
  permit ip any 10.180.210.0 0.0.0.255
  permit ip any 10.180.211.0 0.0.0.255
  permit ip any 10.180.212.0 0.0.0.255
  permit ip any 10.180.213.0 0.0.0.255
  permit ip any 10.180.214.0 0.0.0.255
  permit ip any 10.180.216.0 0.0.0.255
!
!
no ip access-list extended MPLS_ACL_OURO
ip access-list extended MPLS_ACL_OURO
  permit ip host 172.16.8.8 any
  permit ip any host 172.16.8.8
  permit ip 192.168.20.0 0.0.0.255 any
  permit ip any 192.168.20.0 0.0.0.255
  permit ip 192.168.249.0 0.0.0.255 any
  permit ip any 192.168.249.0 0.0.0.255
  permit ip 10.180.43.0 0.0.0.255 any
  permit ip any 10.180.43.0 0.0.0.255
  permit ip host 10.180.22.203 any
  permit ip host 10.180.22.204 any
  permit ip host 10.180.34.201 any
  permit ip host 10.180.41.66 any
  permit ip host 10.180.36.201 any
  permit ip host 10.180.28.201 any
  permit ip host 10.180.30.201 any
  permit ip host 10.180.32.201 any
  permit ip host 10.180.38.201 any
  permit ip host 10.180.24.201 any
  permit ip host 10.180.26.201 any
!
!
no ip access-list extended MPLS_ACL_PRATA
ip access-list extended MPLS_ACL_PRATA
  permit ip host 10.250.62.10 any
  permit ip any host 10.250.62.10
!
!
no ip access-list extended MPLS_ACL_SUPORTE
ip access-list extended MPLS_ACL_SUPORTE
  permit icmp any any
  permit tcp any any eq telnet
  permit tcp any any eq 22
  permit udp any any eq snmp



2) Classes de Servico

class-map match-all MULTIMIDIA
   match access-group name MPLS_ACL_MULTIMIDIA
!
!
class-map match-all OURO
   match access-group name MPLS_ACL_OURO
!
!
class-map match-all PRATA
   match access-group name MPLS_ACL_PRATA
!
!
class-map match-all SUPORTE
   match access-group name MPLS_ACL_SUPORTE
!

3) POLICY
!
policy-map QOS-MPLS-OUT
   class MULTIMIDIA
    priority 73 ---> priorizacao de trafego
    set ip dscp ef
   class OURO
    bandwidth 48 ---> banda alocada
    set ip dscp af31
   class PRATA
    bandwidth 85 --> banda alocada
    set ip dscp af12
   class SUPORTE
    bandwidth 16 ---> banda alocada
    set ip dscp af21
   class class-default
    fair-queue --------------> aloca conforme o que estiver disponivel
    random-detect dscp-based

4) Aplica o policy na interface de saida: FE, GE, FR, PPP, etc.

Cada interface tem seu meio de aplicar ... no caso de FR com 512 kbps:

map-class frame-relay CLASS_QOS
  frame-relay cir 512000
  frame-relay bc 5120
  frame-relay be 0
  frame-relay mincir 512000
  service-policy output QOS-MPLS-OUT
  frame-relay fragment 640 ----------> opcional pois o roteador do outro 
lado do circuito ou rede IP tem que fazer identico !!!

!
!
interface Serial0/0.1 point-to-point
  frame-relay class CLASS_QOS
