使用Modular QoS CLI（MQC）基于FR的DLCI号对包进行分类

 

实验要求
在 R2上基于PVC来分配带宽，PVC201可以分得20％的带宽，PVC203分得55％的带宽

R1
conf t
int s2/0
ip ad 10.1.1.1 255.255.255.0
encap f
no arp f
no frame inver
frame map ip 10.1.1.2 102 b
frame map ip 10.1.1.3 102 b
no shut
end

 

 

R2
conf t
int s 2/0
ip ad 10.1.1.2 255.255.255.0
encap f
no arp f
no frame inver
frame map ip 10.1.1.1 201 b
frame map ip 10.1.1.3 203 b
no shut
exit
class-map match-all PVC201                     步骤1   建立一个class map来表示网络流量
match fr-dlci 201                                                          指定DLCI号作为匹配标准
class-map match-all PVC203
match fr-dlci 203
exit
policy-map PVC                                              步骤2  创建一个policy map
class PVC201                                                              应用class map到policy map中
bandwidth percent 20                                               设定带宽的百分比
class PVC203
bandwidth percent 55
int s2/0
service-policy output PVC                           步骤3  把policy map绑定到接口的出方向
end

 

 

R3
conf t
int s 2/0
ip ad 10.1.1.3 255.255.255.0
encap f
no arp f
no frame inver
frame map ip 10.1.1.1 302 b
frame map ip 10.1.1.2 302 b
no shut
end

 

 

校验
R2#ping 10.1.1.1        

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/39/108 ms

R2#ping 10.1.1.3

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/51/176 ms
