VLAN test 2021.1.14

vlan Big experiment

One , Build topology

Two , Divide vlan
1, take pc1 pc3 Divide into vlan2,
2, take pc2 Divided into vlan2
3, take pc4,pc5 Divided into vlan4
4, take pc6 Divided into vlan5
3、 ... and , Configure switches vlan
[Huawei-Ethernet0/0/1]port link-type access First, define the interface as the access mode

*

Four , establish trunk main rd

trunk main rd — Trunk road It doesn't belong to any one vlan; Carry all vlan Of traffic forwarding ; With mark （ encapsulation VLANID） And identify （ Read , decapsulation VLANID） The ability of ;
[sw1]interface GigabitEthernet 0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk Define interface as trunk Pattern ;

5、 ... and ,dhcp obtain IP Address .

6, Single arm routing , Create sub interfaces . Multi layer switch （SVI）

7、 ... and , Get address

8、 ... and ,ping, Make the whole network accessible .

Different ports differ

vlan Configure basic commands

①VLAN establish ： In global mode vlan 1

② Change the interface mode ： In interface mode switchport mode + Pattern

③ Add ports to VLAN： In interface mode switchport access VLAN

④ Change the port to Trunk Pattern ： In interface mode switchport mode trunk

⑤ Encapsulate the interface 802.1： In interface mode switchport trunk encapsulation dot1q

⑥ Enable routing function ： In global mode ip routing

⑦ For configuration ip Address ： In interface mode ip address ip Address Subnet mask

⑧ Open port ： In interface mode no shutdown

⑨ Virtual ports ： In global mode interface fastEthernet 0/0._ _ by VLAN Number

⑩ encapsulation 802.1：Router(config-subif)# encapsulation dot1Q VLAN Number
