VLAN实验报告

ii1，将PC设置成用DHCP获取IP地址

2，创建vlan

[LSW1]vlan batch 2 to 6
[LSW2]vlan batch 2 to 6
[LSW3]vlan batch 2 to 6

3，进入接口加入vlan

LSW1

[LSW1]int g 0/0/1	
[LSW1-GigabitEthernet0/0/1]port link-type access 
[LSW1-GigabitEthernet0/0/1]port default vlan 2

[LSW1]int g 0/0/2	
[LSW1-GigabitEthernet0/0/2]port hybrid pvid vlan 3
[LSW1-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 6

[LSW1-GigabitEthernet0/0/2]int g 0/0/3
[LSW1-GigabitEthernet0/0/3]port link-type trunk
[LSW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 to 6

[LSW1-GigabitEthernet0/0/3]int g 0/0/4
[LSW1-GigabitEthernet0/0/4]port hybrid untagged vlan 3 to 6
[LSW1-GigabitEthernet0/0/4]port hybrid tagged vlan 2


LSW2

[LSW2]interface g 0/0/1
[LSW2-GigabitEthernet0/0/1]port link-type access 
[LSW2-GigabitEthernet0/0/1]port default vlan 2
[LSW2-GigabitEthernet0/0/1]int g 0/0/2

[LSW2-GigabitEthernet0/0/2]port hybrid pvid vlan 4
[LSW2-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 6

[LSW2-GigabitEthernet0/0/2]int g 0/0/3
[LSW2-GigabitEthernet0/0/3]port link-type trunk
[LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 to 6

[LSW2-GigabitEthernet0/0/3]int g 0/0/4
[LSW2-GigabitEthernet0/0/4]port link-type trunk
[LSW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 to 6

LSW3
[LSW3]int g 0/0/1
[LSW3-GigabitEthernet0/0/1]port hybrid pvid vlan 5
[LSW3-GigabitEthernet0/0/1]port hybrid untagged vlan 3 4 5

[LSW3-GigabitEthernet0/0/1]int g 0/0/2	
[LSW3-GigabitEthernet0/0/2]port hybrid pvid vlan 6
[LSW3-GigabitEthernet0/0/2]port hybrid untagged vlan 3 4 6

[LSW3-GigabitEthernet0/0/2]int g 0/0/3
[LSW3-GigabitEthernet0/0/3]port link-type trunk 
[LSW3-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 to 6

4，R1上：

子接口——vlan2

物理口——vlan3,4,5,6

[R1]int g 0/0/0
[R1-GigabitEthernet0/0/0]ip add	
[R1-GigabitEthernet0/0/0]ip address 192.168.1.1 24

[R1-GigabitEthernet0/0/0]int g 0/0/0.1	
[R1-GigabitEthernet0/0/0.1]ip address 192.168.2.1 24
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 2 //接口开启802.1q帧识别
[R1-GigabitEthernet0/0/0.1]arp broadcast enable //开启arp广播协议

5，配置地址池

[R1]dhcp enable 
[R1]ip pool aa
[R1-ip-pool-aa]network 192.168.2.0 mask 24	
[R1-ip-pool-aa]gateway-list 192.168.2.1
[R1-ip-pool-aa]dns-list 8.8.8.8
[R1]int g 0/0/0.1
[R1-GigabitEthernet0/0/0.1]dhcp select global 

[R1]dhcp enable 
[R1]ip pool bb
[R1-ip-pool-bb]network 192.168.1.0 mask 24
[R1-ip-pool-bb]gateway-list 192.168.1.1
[R1-GigabitEthernet0/0/0]dhcp select global 

PC1：192.168.2.254
PC2：192.168.1.252
PC3：192.168.2.253
PC4：192.168.1.253
PC5：192.168.1.254
PC6：192.168.1.251

PC2 访问PC4/5/6

PC4 访问PC6：

PC5 不能访问PC6
