VLAN

vlan

1.在全局配置模式下建立虛拟區域網路

Switch#configure terminal

Switch(config)#vlan 2              建立vlan2

Switch(config-vlan)#name ff       給vlan2命名

Switch(config-vlan)#vlan 3

Switch(config-vlan)#name jj

Switch(config)#interface f0/1      分别将f0/1,f0/2加入到vlan2中

Switch(config-if)#switchport access vlan 2

Switch(config-if)#exit

Switch(config)#interface f0/2

Switch(config)#interface range f0/3-4    一次性将f0/3,f0/4加入到vlan3中

Switch(config-if-range)#switchport access vlan 3

Switch#show vlan

VLAN Name                             Status    Ports

---- -------------------------------- --------- -------------------------------

1    default                          active    Fa0/5, Fa0/6, Fa0/7, Fa0/8

                                                Fa0/9, Fa0/10, Fa0/11, Fa0/12

                                                Fa0/13, Fa0/14, Fa0/15, Fa0/16

                                                Fa0/17, Fa0/18, Fa0/19, Fa0/20

                                                Fa0/21, Fa0/22, Fa0/23, Fa0/24

2    ff                              active    Fa0/1, Fa0/2

3    jj                              active    Fa0/3, Fa0/4

測試連通性，得出實驗結果

2.在特權模式下建立虛拟區域網路

Switch>enable

Switch#vlan database    進入虛拟區域網路資料庫

Switch(vlan)#vlan 2 name ff    在庫中建立vlan2,3

Switch(vlan)#vlan 3 name jj

1    default                          active    Fa0/1, Fa0/2, Fa0/3, Fa0/4

                                                Fa0/5, Fa0/6, Fa0/7, Fa0/8

2    ff                              active   

3    jj                              active   

Switch#conf t

Switch(config)#interface range f0/1-2    一次性将f0/1,f0/2加入到vlan2中

Switch(config-if-range)#switchport access vlan 2

Switch(config-if-range)#exit

3.從虛拟區域網路中删除某個接口

Switch(config)#int f0/1

Switch(config-if)#no switchport access vlan 2

Switch(config-if)#end

1    default                          active    Fa0/1, Fa0/5, Fa0/6, Fa0/7

                                                Fa0/8, Fa0/9, Fa0/10, Fa0/11

                                                Fa0/12, Fa0/13, Fa0/14, Fa0/15

                                                Fa0/16, Fa0/17, Fa0/18, Fa0/19

                                                Fa0/20, Fa0/21, Fa0/22, Fa0/23

                                                Fa0/24

2    ff                              active    Fa0/2

4.删除空vlan

Switch(config)#no vlan 3

如果虛拟區域網路中有接口，是不能直接删除目前的vlan的。

5.将多個接口同時加入一個虛拟區域網路中

Switch(config)#interface range f0/5-7,f0/9,f0/11-15

1    default                          active    Fa0/1, Fa0/8, Fa0/10, Fa0/16

2    ff                              active    Fa0/2, Fa0/5, Fa0/6, Fa0/7

                                                Fa0/9, Fa0/11, Fa0/12, Fa0/13

                                                Fa0/14, Fa0/15
