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关键字表示使用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-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

3、FR配置：
interface Serial0/1
description Parent FR Link

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
