QoS CAR 和GTS实验

 实验目的：   熟悉CAR 流量监管和GTS流量整形

              理解QOS是如何工作的

 

实验拓扑

 

 

 

 

实验思路

 

    在R2的S0/6/0上作CAR

 

    在R1的S0/6/0上作GTS

 

实验配置

测试：

 

1、用R1 R3 的loop back 口ping R2的loopback 口

 

在R2上查看如下信息

 

<R2>dis qos car interface 

Interface: Serial0/6/0

Direction: Inbound

  Rule(s): If-match acl 3001

  CIR 8000 (kbps),  CBS 15000 (byte),  EBS 0 (byte)

  Green Action: pass

  Red Action : discard

  Green : 16294(Packets) 20801400(Bytes)  

  Yellow: 0(Packets) 0(Bytes)  

  Red   : 0(Packets) 0(Bytes) 

  Rule(s): If-match acl 3000

  CIR 8000 (kbps),  CBS 15000 (byte),  EBS 0 (byte)

  Green Action: pass

  Red Action : discard

  Green : 12022(Packets) 16286384(Bytes)  

  Yellow: 0(Packets) 0(Bytes)  

  Red   : 0(Packets) 0(Bytes)

在R1上配置完成GTS后作测试

 CIR 8000 (kbps), CBS 15000 (byte), EBS 0 (byte)

 Passed   : 0(Packets) 0(Bytes)  

 Discarded: 0(Packets) 0(Bytes)
