  五、WAN Qos配置与远程办公室Qos配置
  
    在路由器上使用模块化QOS命令行(MQC,12.2T),配置分为三部分:
  
  class-map:对流量分类
  policy-map:对每类流量分配queue,PRiority要害字表示使用LLQ。
  server-policy:将policy-map绑定到接口上。
  1、Policy-map配置
  
  class-map match-all VOICE
  
  match ip dscp ef
  
  class-map match-all VIDEO
  
  match ip dscp af41
  
  class-map match-all VOICE-CONTROL
  
  match ip dscp af31
  
  class-map match-any GOLD-DATA
  
  match ip dscp af21
  
  match ip dscp af22
  
  match ip dscp af23
  
  class-map match-any SILVER-DATA
  
  match ip dscp af11
  
  match ip dscp af12
  
  match ip dscp af13
  
  !
  
  policy-map WAN-EDGE
  
  class VOICE
  
  priority percent 17
  
  class VIDEO
  
  priority percent 16 30000
  
  class VOICE-CONTROL
  
  bandwidth percent 2
  
  class GOLD-DATA
  
  bandwidth percent 25
  
  random-detect dscp-based
  
  class SILVER-DATA
  
  bandwidth percent 15
  
  random-detect dscp-based
  
  class class-default
  
  fair-queue
  
  random-detect dscp-based
  
  random-detect dscp-based
  
  random-detect dscp 0 96 128 10
  
  random-detect dscp 2 70 128 10
  
  random-detect dscp 4 58 128 10
  
  random-detect dscp 6 44 128 10
  
  2、PPP配置
  
  interface Multilink 40
  
  bandwidth 4096
  
  ip address 10.200.40.1 255.255.255.252
  
  service-policy output WAN-EDGE
  
  ppp multilink
  
  multilink-group 40
  
  interface Serial1/0
  
  description Link E1-A to BRANCH#40
  
  bandwidth 2048
  
  no ip address
  
  encapsulation ppp
  
  ppp multilink
  
  multilink-group 40
  
  interface Serial1/1
  
  description Link E1-B to BRANCH#40
  
  bandwidth 4096
  
  no ip address
  
  encapsulation ppp
  
  ppp multilink
  
  multilink-group 40
  
  3、FR配置:
  
  interface Serial0/1
  
  description Parent FR Link
  
  no ip address
  
  encapsulation frame-relay
  
  !
  
  interface Serial0/1.50 point-to-point
  
  description FR Link to BRANCH#50
  
  bandwidth 3000
  
  ip address 10.200.50.1 255.255.255.252
  
  frame-relay interface-dlci 211
  
  class REMOTE-BRANCH-3000kbps
  
  map-class frame-relay REMOTE-BRANCH-3000kbps
  
  frame-relay cir 3000000
  
  frame-relay bc 30000
  
  frame-relay be 0
  
  frame-relay mincir 3000000
  
  no frame-relay adaptive-shaping
  
  service-policy output WAN-EDGE
  
  4、ATM配置
  
  interface ATM4/0
  
  bandwidth 3000
  
  no ip address
  
  no atm ilmi-keepalive
  
  !
  
  interface ATM4/0.60 point-to-point
  
  bandwidth 3000
  
  ip address 10.210.60.1 255.255.255.252
