Qos实验初体验

1.分类和标记

2.管制和整形

3.拥塞管理

4.拥塞避免

实验拓扑：

1.配置管制：(超过额定带宽，处理方式丢包)

R2：

//抓取地址，调用ACL，配置Police-map

access-list 101 permit ip 10.1.1.0 0.0.0.255 any

class-map match-all 101

 match access-group 101

policy-map 101

 class 10

 police cir 8000 bc 2000

//接口调用police-map

interface Ethernet0/0

 ip address 12.1.1.2 255.255.255.0

 service-policy output 101

 

效果：

R1#ping 10.1.1.1 size 2000 repeat 1000

Type escape sequence to abort.

Sending 1000, 2000-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:

!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.

!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.!.

Success rate is 50 percent (70/140), round-trip min/avg/max = 1/4/92 ms

R1#ping 20.1.1.1 size 2000 repeat 1000

Type escape sequence to abort.

Sending 1000, 2000-byte ICMP Echos to 20.1.1.1, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Success rate is 100 percent (873/873), round-trip min/avg/max = 1/3/12 ms

2.配置整形(超过额定带宽，将流量缓存到内存中，等待传输。不丢包)

R2:

access-list 102 permit ip 10.1.1.0 0.0.0.255 any

class-map match-all shape102

 match access-group 102

policy-map shape102

 class shape102

 shape average 8000 2000

interface Ethernet0/0

 ip address 12.1.1.2 255.255.255.0

 service-policy output shape102

效果 ：

R1#ping 10.1.1.1 size 2000 repeat 100 

Type escape sequence to abort.

Sending 100, 2000-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!.

Success rate is 98 percent (84/85), round-trip min/avg/max = 24/1496/1552 ms

R1#ping 20.1.1.1 size 2000 repeat 100

Type escape sequence to abort.

Sending 100, 2000-byte ICMP Echos to 20.1.1.1, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Success rate is 100 percent (100/100), round-trip min/avg/max = 1/3/16 ms
