1 Mục tiêu:

Đánh dấu packet bằng DSCP

Cấu hình class-based TCP Header Compression

Cấu hình class-based traffic shaping and policing

Create and apply nested service policies

2 Cấu hình:

Step 1: Cấu hình địa chỉ IP như hình vẽ:

R1(config)# interface fastethernet 0/0

R1(config-if)# ip address 172.16.10.1 255.255.255.0

R1(config-if)# no shutdown

R1(config-if)# interface fastethernet 0/1

R2(config)# interface serial 0/0/1

R2(config-if)# bandwidth 800

R2(config-if)# clockrate 800000

R3(config-if)# interface serial 0/1/0

R4(config-if)# interface serial 0/0/0

TrafGen# tgn start

Step 2: Cấu hình định tuyến bằng OSPF :

R1(config)# router ospf 1

R1(config-router)# network 172.16.0.0 0.0.255.255 area 0

Step 3: Đánh dấu packet bằng DSCP:

R1(config)# class-map match-any critical

R1(config-cmap)# match protocol ospf

R1(config-cmap)# match protocol ntp

R1(config-cmap)# class-map match-any interactive

R1(config-cmap)# match protocol telnet

R1(config-cmap)# match protocol ssh

R1(config-cmap)# match protocol xwindows

R1(config-cmap)# class-map match-any web

R1(config-cmap)# match protocol http

R1(config-cmap)# match protocol pop3

R1(config-cmap)# match protocol smtp

R1(config)# policy-map markingpolicy

R1(config-pmap)# class critical

R1(config-pmap-c)# set dscp ef

R1(config-pmap-c)# class interactive

R1(config-pmap-c)# set dscp af41

R1(config-pmap-c)# class web

R1(config-pmap-c)# set dscp af32

R1(config-pmap-c)# class class-default

R1(config-pmap-c)# set dscp default

R1(config-pmap-c)# interface fastethernet0/1

Step 4: Caáu hình Class-based Shapping:

R4(config)# policy-map shapingpolicy

R4(config-pmap)# class class-default

R4(config-pmap-c)# shape peak 400000

R4(config-pmap-c)# interface serial0/0/0

R4(config-if)# service-policy output shapingpolicy

Trang 4

Step 5: Caáu hình Nested Service Policies:

R4(config)# class-map ef

R4(config-cmap)# match dscp ef

R4(config-cmap)# class-map af41

R4(config-cmap)# match dscp af41

R4(config-cmap)# class-map af32

R4(config-cmap)# match dscp af32

R4(config-cmap)# policy-map innerpolicy

R4(config-pmap)# class ef

R4(config-pmap-c)# class af41

R4(config-pmap-c)# class af32

R4(config-pmap-c)# policy-map shapingpolicy

R4(config-pmap-c)# service-policy innerpolicy

Trang 5

Step 6: Caáu hình Traffic Policing:

R3(config)# policy-map policingpolicy

R3(config-pmap-c)# police rate 400000 bps

R3(config-pmap-c-police)# interface serial0/0/1

R3(config-if)# service-policy output policingpolicy

Trang 6

Step 7: Caáu hình Class-based TCP Header Compression

R4(config)# policy-map innerpolicy

R4(config-pmap)# class af32

R4(config-pmap-c)# compression header ip tcp
