VLAN experiment

One 、 The experimental requirements

Two 、 The topology

3、 ... and 、 Experimental configuration

1. To configure sw1

It can be seen from the picture that pc1,pc3 stay vlan2 And the interface mode is access Interface

take sw1 Upper 0/0/2 The interface is divided into vlan2

[sw1]vlan batch 2
[sw1]int e 0/0/2	
[sw1-Ethernet0/0/2]port link-type access 
[sw1-Ethernet0/0/2]port default vlan 2

because pc2/4/5/6 In the same segment , And pc2 Access to 456,4 and 5 Cannot access 6,0/0/3 The interface is divided into vlan3, allow vlan3/4/5 Get into

[sw1] vlan batch 3 to 5
[sw1-Ethernet0/0/4]int e 0/0/3		
[sw1-Ethernet0/0/3]port hybrid pvid vlan 3
[sw1-Ethernet0/0/3]port hybrid untagged vlan 3 to 5

because pc1/3 And 2/4/5/6 Not in the same network segment , And all pc All equipment must pass dhcp obtain ip, therefore 0/0/4 The interface to vlan2 Put a label on it ,vlan3/4/5 Without a label

[sw1]int e 0/0/4
[sw1-Ethernet0/0/4]port hybrid tagged vlan 2
[sw1-Ethernet0/0/4]port hybrid untagged vlan 3 to 5

e0/0/5 Interface for trunk Plank road

[sw1-Ethernet0/0/3]int e 0/0/5
[sw1-Ethernet0/0/5]port link-type trunk 
[sw1-Ethernet0/0/5]port trunk allow-pass vlan 2 to 5

2. To configure sw2

e0/0/1 by trhunk Plank road , Use hybrid mode

[sw2]vlan batch 3 to 5
[sw2]int e 0/0/1
[sw2-Ethernet0/0/1]port hybrid tagged vlan 2 to 5

e0/0/3 Interface for access The interface is divided into vlan2, because pc2 Access to pc456, So allow vlan3/4/5 Get into

[sw2]vlan 2	
[sw2-vlan2]int e 0/0/3
[sw2-Ethernet0/0/3]port link-type access 
[sw2]vlan batch 3 to 5

e0/0/4 into vlan4, because pc4 and pc5 Cannot access 6, therefore pc4 and pc5 into vlan4, And allow vlan3/4 Get into , Don't allow vlan5 Get into

[sw2-Ethernet0/0/1]int e 0/0/4	
[sw2-Ethernet0/0/4]port hybrid pvid vlan 4
[sw2-Ethernet0/0/4]port hybrid untagged vlan 3 to 4

e0/0/2 by trunk Plank road

[sw2-Ethernet0/0/4]int e 0/0/2
[sw2-Ethernet0/0/2]port link-type trunk 	
[sw2-Ethernet0/0/2]port trunk allow-pass vlan 2 to 5

3. To configure sw3

e0/0/1 For hybrid mode ,trunk Plank road

[sw3] vlan batch 2 to 5
[sw3]int e 0/0/1
[sw3-Ethernet0/0/1]port hybrid tagged vlan 2 to 5

e0/0/2 into vlan4, allow vlan3/4 Get into , Don't allow vlan5 Get into

[sw3-Ethernet0/0/1]int e 0/0/2
[sw3-Ethernet0/0/2]port hybrid pvid vlan 4
[sw3-Ethernet0/0/2]port hybrid untagged  vlan 3 to 4

because pc4pc5 Cannot access pc6, therefore e0/0/3 into vlan5, allow vlan3/5 Get into

[sw3-Ethernet0/0/2]int e 0/0/3	
[sw3-Ethernet0/0/3]port hybrid pvid vlan 5	
[sw3-Ethernet0/0/3]port hybrid untagged vlan 3 5

4. Configure router

because vlan3/4/5 No label , So the vlan3/4/5 Transfer in g0/0/0 Physical interface , hold vlan2 Transfer in g0/0/0.1 A subinterface

To configure g0/0/0 Interface ip

[Huawei]int g 0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 192.168.1.254 24

Transfer in sub interface

[Huawei]int g 0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 2
[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable 

Turn on dhcp Division of services dhcpIP pond

[Huawei]dhcp enable 
[Huawei]ip pool vlan2

[Huawei]ip pool vlan345	
[Huawei-ip-pool-vlan345]network 192.168.2.0 mask 24
[Huawei-ip-pool-vlan345]gateway-list 192.168.2.254 
[Huawei-ip-pool-vlan345]dns-list 114.114.114.114

take vlan2dhcp Ponds are used in g0/0/0.1 Interface

[Huawei-GigabitEthernet0/0/0]int g 0/0/0.1	
[Huawei-GigabitEthernet0/0/0.1]dhcp select global

take vlan345 Apply to g0/0/0 Interface

[Huawei-ip-pool-vlan345]int g 0/0/0
[Huawei-GigabitEthernet0/0/0]dhcp select global
