第20章 交换机限速配置

1.SW1配置VLAN

[SW1]vlan batch 10 20
[SW1]interface GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1]port link-type trunk 
[SW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10  
[SW1]interface GigabitEthernet 0/0/2
[SW1-GigabitEthernet0/0/2]port link-type trunk
[SW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
[SW1]interface GigabitEthernet 0/0/3
[SW2-GigabitEthernet0/0/3]port link-type trunk
[SW2-GigabitEthernet0/0/3]port trunk allow-pass vlan all

2.SW1配置ACL

[SW1]acl number 2001
[SW1-acl-basic-2001]rule permit source 192.168.10.0 0.0.0.255
[SW1]acl number 2002 
[SW1-acl-basic-2002]rule permit source 192.168.20.0 0.0.0.255

3.SW1配置流分类

[SW1]traffic classifier vlan10
[SW1-classifier-vlan10]if-match acl 2001
[SW1]traffic classifier vlan20
[SW1-classifier-vlan20]if-match acl 2002

4.SW1配置流行为

[SW1]traffic behavior vlan10
[SW1-behavior-vlan10]car cir 2000 cbs 376000 pbs 626000 green pass yellow pass red discard
//对VLAN10限速2M
[SW1]traffic behavior vlan20 
[SW1-behavior-vlan20]car cir 4096 
//对VLAN10限速4M

5.SW1配置流策略

[SW1]traffic policy vlan1020
[SW1-trafficpolicy-vlan1020]classifier vlan10 behavior vlan10
[SW1-trafficpolicy-vlan1020]classifier vlan20 behavior vlan20

6.接口应用策略

[SW1]interface GigabitEthernet 0/0/3
[SW1-GigabitEthernet0/0/3]traffic-policy vlan1020 inbound      
[SW1-GigabitEthernet0/0/1]traffic-policy vlan1020 outbound

7.SW2配置

[SW2]interface GigabitEthernet 0/0/1
[SW2-GigabitEthernet0/0/1]port link-type trunk 
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[SW2]interface GigabitEthernet 0/0/2
[SW2-GigabitEthernet0/0/2]port link-type access
[SW2-GigabitEthernet0/0/2]port default vlan 10

8.SW3配置

[SW3]interface GigabitEthernet 0/0/1
[SW3-GigabitEthernet0/0/1]port link-type access 
[SW3-GigabitEthernet0/0/1]port default vlan 20
[SW3]interface GigabitEthernet 0/0/2
[SW3-GigabitEthernet0/0/2]port link-type trunk 
[SW3-GigabitEthernet0/0/2]port trunk allow-pass vlan all
