　　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

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

3、FR配置：

interface Serial0/1

description Parent FR Link
